In the world of tomatoes there are different varieties, many of which are protected from crossing due to the structure of their flowers. This is because its flowers have a special structure: the stigma, part of the flower's female reproductive organ, is hidden inside the calyx. This means that cross-pollination is virtually impossible, although in rare cases it can still occur. If tomatoesgrown without any special measures and simply allowed to grow is called“unprevented” cultivation . However, there is a way to prevent cross-pollination: you can, for exampleThe still closed flowers of the plant form a fine network or aspecial bag , such as an organza bag. This process is called “contraception.” Through this protective bag pollination by insects is prevented, and the seeds are thusdefinitely pure , as no crossings can take place. Zurück zur Übersicht

Zurück zu Tomatopedia Zurück zu Bilddiagnose powdery mildew Tomato plants are very popular among gardeners around the world, but they are also susceptible to various diseases. One of the most common and annoying is powdery mildew, which is caused by fungi of the genus Oidium. This disease can severely affect the growth and yield of plants if not detected and treated in time. Causes of Powdery Mildew in Tomato Plants Powdery mildew is a common fungal disease that can affect tomato plants. Here are the most common causes: High humidity The fungus thrives particularly well in high humidity, which promotes the spread of spores. Warm weather Warm temperatures, especially with high humidity, create ideal conditions for the fungus. Poor air circulation The fungus can spread quickly in closely spaced plants or poorly ventilated greenhouses. Infected plant remains Fungal spores can overwinter on infected plant remains and become active again the following year. overhead irrigation If the leaves get wet during watering, this promotes the spread of mildew. Measures to Control Powdery Mildew in Tomatoes To combat powdery mildew, the following measures can be taken: reduce humidity Improve air circulation around plants to reduce humidity. This can be achieved by thinning plants or opening greenhouse windows. adjust water supply Water the plants directly at the ground, making sure the leaves stay dry. Watering in the morning is ideal, as this allows the leaves to dry out during the day. Apply milk-water spray A mixture of one part milk and nine parts water can be sprayed on the affected plants. The lactic acid bacteria help to fight the fungus. Pay attention to floor hygiene Infected plant remains should be removed and disposed of to prevent transmission to the next growing season. monitor temperatures In greenhouses, maintain adequate temperature control to minimize conditions for fungal growth. Regular check-ups Check plants regularly for signs of mildew so that early action can be taken. These measures help reduce or prevent powdery mildew on tomato plants and keep the plants healthy.

Erfahren, warum Tomaten während der Saison aufplatzen und wie dieses häufige Problem vermieden werden kann. Dieser Artikel erklärt die Ursachen für das Aufplatzen von Tomaten, wie ungleichmäßige Bewässerung, Temperaturschwankungen und Sortenunterschiede. Er enthält außerdem praktische Tipps zur Vorbeugung und Pflege der Tomatenpflanzen, um gesunde, unbeschädigte Früchte zu ernten. Zurück zu Tomatopedia Zurück zu Bilddiagnose Warum platzen Tomaten während der Saison auf? Viele Gärtner kennen das Ärgernis: Die Tomaten im Garten oder auf dem Balkon sehen prächtig aus, doch plötzlich beginnen sie aufzuplatzen. Dieses häufige Problem kann den Anbau von Tomaten erschweren und die Freude an der Ernte trüben. Die unschönen Risse in der Tomatenhaut beeinträchtigen nicht nur den Genuss, sondern auch die Lagerfähigkeit der Früchte. Das Aufplatzen von Tomaten hat verschiedene Ursachen und tritt häufiger auf. Ursachen für das Aufplatzen von Tomaten Ungleichmäßige Bewässerung Der Hauptgrund für das Aufplatzen von Tomaten ist ungleichmäßige Bewässerung. Wenn die Pflanze nach einer trockenen Phase plötzlich viel Wasser aufnimmt, dehnen sich die Früchte schneller aus, als ihre Schale wachsen kann. Dies führt zu Rissen in der Haut der Tomaten. Temperaturschwankungen Große Unterschiede zwischen Tages- und Nachttemperaturen können ebenfalls zum Aufplatzen von Tomaten führen. Die schnellen Temperaturwechsel stressen die Pflanze und beeinträchtigen ihre Fähigkeit, Wasser gleichmäßig aufzunehmen und zu verteilen. S ortenunterschiede Einige Tomatensorten sind anfälliger für das Aufplatzen als andere. Sorten mit dünnerer Haut oder größeren Früchten neigen eher dazu, unter diesen Bedingungen zu leiden. Übermäßige Düngung Eine zu hohe Konzentration von Stickstoff im Boden kann zu einem schnellen Wachstum der Pflanze und ihrer Früchte führen, was die Wahrscheinlichkeit von Rissen erhöht. Praktische Tipps zur Vorbeugung Gleichmäßige Bewässerung Achten Sie darauf, Ihre Tomatenpflanzen gleichmäßig zu bewässern. Vermeiden Sie längere Trockenperioden und stellen Sie sicher, dass die Pflanzen regelmäßig und ausreichend Wasser erhalten. Mulchen kann helfen, die Bodenfeuchtigkeit zu regulieren und Schwankungen zu minimieren. Temperatur Wenn möglich, sollte die Pflanzen vor extremen Temperaturschwankungen geschützt werden. Dies kann durch die Verwendung von Schattierungsnetzen oder den Anbau in Gewächshäusern erreicht werden. Wahl der Sorte Es ist ratsam, Tomatensorten zu wählen, die weniger anfällig für das Aufplatzen sind. Es gibt speziell gezüchtete Sorten, die widerstandsfähiger gegen Risse sind. Richtige Düngung Eine übermäßige Düngung mit stickstoffreichem Dünger sollte vermieden werden. Stattdessen empfiehlt es sich, einen ausgewogenen Dünger zu verwenden, der ein gleichmäßiges Wachstum der Pflanze fördert. Erntezeitpunkt Ernten Sie die Tomaten rechtzeitig. Überreife Tomaten neigen eher zum Aufplatzen. Kontrollieren Sie Ihre Pflanzen regelmäßig und pflücken Sie die Früchte, wenn sie reif sind, aber noch fest. Bodenpflege Es sollte sicher gestellt werden, dass der Boden gut drainiert ist und keine Staunässe entsteht. Ein gut belüfteter Boden mit ausreichendem organischem Material fördert ein gesundes Wurzelwachstum und eine gleichmäßige Wasseraufnahme. Weitere Tipps zur Pflege Ihrer Tomatenpflanzen Mulchen Mulchen hilft nicht nur bei der Wasserregulierung, sondern auch dabei, die Bodentemperatur konstant zu halten und Unkrautwachstum zu verhindern. Regelmäßige Kontrolle Die Pflanzen sollten regelmäßig auf Anzeichen von Krankheiten oder Schädlingen überprüft werden, die das Wachstum und die Gesundheit der Tomaten beeinträchtigen könnten. Stützen Es ist ratsam Tomatenkäfige oder Stäbe zu benutzen, um die Pflanzen zu stützen. Dies verhindert, dass die Früchte den Boden berühren, wo sie eher beschädigt werden können. Tomato cracking is a common problem caused by uneven watering, temperature fluctuations and other factors. With the right preventive measures and careful care, it is possible to harvest healthy, undamaged tomatoes. By using consistent watering, choosing resistant varieties and balanced fertilization, the risk of cracking can be minimized and a successful tomato harvest can be achieved.

Why does the taste of a tomato suffer when too many leaves are removed? Removing too many leaves from a tomato plant can negatively impact the flavor and health of the tomato fruit for several reasons: Photosynthesis and nutrient absorption : The leaves of a plant are responsible for photosynthesis, a process in which the plant converts light energy into sugars and absorbs nutrients. Removing too many leaves reduces the plant's ability to absorb sufficient nutrients and produce energy, which can result in smaller and less tasty fruits. fruit ripening : The leaves are also important in regulating fruit ripening. They influence the plant's metabolism and the production of hormones that control fruit development. Removing too many leaves can cause the fruit to remain unripe or slow its ripening. sunburn : The leaves also serve to protect the fruit from direct sunlight. Removing too many leaves can expose the tomatoes to intense sun, which can lead to sunburn. This can lead to discoloration and loss of taste. Moisture regulation : The leaves help regulate moisture in the plant by allowing water to evaporate. If too many leaves are removed, the plant may have difficulty maintaining moisture, which can lead to drought stress and flavor-altering effects. It is important to perform leaf removal from tomato plants with caution and be aware that some degree of leaf removal, particularly of lower leaves, may sometimes be necessary to improve the plant's aeration and reduce the likelihood of disease . However, a balanced approach is crucial to maintaining the health and flavor of the tomatoes. It is important to perform leaf removal from tomato plants with caution and to be aware that some degree of leaf removal, especially of lower leaves, may sometimes be necessary to improve aeration of the plant and reduce the likelihood of disease.

Erfahre, wie man den perfekten Standort für Tomaten wählt: in Bezug auf Sonneneinstrahlung, Bodenbeschaffenheit, Luftzirkulation, Wärme, Wasserversorgung sowie Schutz vor extremen Wetterbedingungen. So gedeihen die Tomatenpflanzen optimal! Zurück zur Übersicht The ideal location for tomatoes: tips for good yields and healthy plants The perfect location for tomatoes depends on several factors to ensure that the plants thrive and produce abundant fruit. Here are the most important points: Solar radiation Tomatoes need a lot of sunlight, ideally at least 6-8 hours of direct sunlight per day. A sunny location is therefore crucial. Soil condition The soil should be well-drained and rich in nutrients. A loamy, sandy soil with a high humus content is ideal. The pH values should be slightly acidic to neutral (between 6.0 and 7.0). Air circulation Good air circulation helps prevent diseases such as mildew. Make sure plants are not too close together and have enough space. warmth Tomatoes love warmth and thrive best at temperatures between 18-25°C. A sheltered location that is protected from strong winds and cold is ideal. Water supply Tomatoes require regular and consistent watering. The soil should be moist but not waterlogged. Mulching helps maintain soil moisture. Protection from heavy rain A location that is protected from heavy rain can help reduce the risk of fungal diseases. A covered area or greenhouse can be beneficial. A sunny, warm location with well-drained, nutrient-rich soil and good air circulation is perfect for growing tomatoes. Regular watering and protection from extreme weather conditions also contribute to optimal growth. Zurück zur Übersicht

Magnesiummangel bei Tomaten zeigt sich durch gelbe Flächen zwischen grünen Blattadern an älteren Blättern. Ursache ist meist ein gestörter Nährstofftransport im Boden. Eine gezielte Blattdüngung mit Magnesium oder Bittersalz schafft schnelle Abhilfe. Zurück zu Tomatopedia Zurück zu Bilddiagnose Magnesiummangel bei Tomaten – wenn die Adern grün bleiben und der Rest gelb wird Wenn sich bei Tomaten die Blattzwischenräume gelb verfärben, während die Blattadern grün bleiben, liegt der Verdacht auf Magnesiummangel nahe. Besonders betroffen sind meist die älteren, unteren Blätter. Mit der Zeit breitet sich die Gelbfärbung aus, und es können erste braune Flecken am Blattrand entstehen. Woran erkenne ich Magnesiummangel? Zwischenaderchlorose: Die Flächen zwischen den Adern werden gelb, die Adern selbst bleiben grün. Standort der Symptome: Betroffen sind vor allem ältere Blätter unten an der Pflanze. Spätere Stadien: Die gelben Bereiche werden größer, es treten Nekrosen (trockene braune Stellen) auf. Verwechslung mit Kaliummangel: Beim Kaliummangel beginnen die Symptome an den Blatträndern – beim Magnesiummangel sitzen sie zwischen den Adern. Magnesiummangel Tomatenblatt mit beginnenden Anzeichen eines Magnesiummangels Magnesiummangel Tomatenblatt mit beginnenden Anzeichen eines Magnesiummangels Magnesiummangel Nahaufnahme Tomatenblatt mit eindeutigem Magnesiummangel Tomatenblatt mit Magnesiummangel Tomatenblatt mit deutlich ausgeprägtem Magnesiummangel. Warum tritt Magnesiummangel auf? Magnesium ist ein sogenannter mobiler Nährstoff – bei Mangel wird es aus älteren Blättern in die neuen umverteilt. Häufige Ursachen: Einseitige Düngung, z. B. mit stickstoff- oder kaliumbetonten Düngern Hoher pH-Wert oder Kalküberschuss im Boden Stark zehrende Pflanzen im Beet ohne Nachdüngung Konkurrenz mit Calcium und Kalium: Diese Nährstoffe können die Magnesiumaufnahme blockieren Was tun? Kurzfristig helfen: 1–2 Blattdüngungen mit Bittersalz (Magnesiumsulfat, 2 % Lösung – 20 g/Liter Wasser). Langfristig vorbeugen: Magnesium über den Boden ausgleichen – z. B. mit kieseritbasierten Düngern. Gießwasser prüfen: Stark kalkhaltiges Wasser kann auf Dauer zu Blockaden führen. Schnelle Alternativen zu Bittersalz (Magnesiumsulfat) 1. Flüssigdünger mit Magnesium Enthält direkt pflanzenverfügbares Magnesium (2–4 % Mg) Schnelle Wirkung, sofort einsetzbar Geeignet zur Gieß- oder Spritzanwendung Beispiele: Bio-Trissol Tomatendünger, Compo Tomaten Liquid 2. Dolomitkalk (kohlensaurer Magnesiumkalk) Kombination aus Calcium und Magnesium Ideal bei saurem Boden (pH unter 6,5) Langsamer, aber nachhaltiger Effekt Granulat direkt auf den Boden streuen 3. Gartenkalk mit Magnesiumanteil Einige Gartenkalke enthalten zusätzlich Magnesium Bodenneutralisierend + Magnesiumversorgung Vorsicht bei kalkempfindlichen Kulturen und hohem pH 4. Volldünger mit Magnesiumanteil In fester oder flüssiger Form erhältlich Für Gieß- oder Blattdüngung geeignet (Etikett prüfen) Nur verwenden, wenn kein Übermaß an Stickstoff zugeführt wird Nicht geeignet als Magnesiumquelle: Kompost, Hornspäne, Brennnesseljauche, Kaffeesatz – enthalten kaum verwertbares Magnesium. Bei akutem Mangel schnellstmöglich einen Mg-haltigen Flüssigdünger einsetzen – sichtbarste Wirkung innerhalb weniger Tage. Magnesiummangel sieht dramatisch aus, ist aber mit richtiger Reaktion gut in den Griff zu bekommen. Wird nicht gegengesteuert, leidet die Pflanze dauerhaft – Blattfläche geht verloren, Photosynthese wird eingeschränkt, Ertrag sinkt. Zurück zu Tomatopedia Zurück zu Bilddiagnose

Die Dürrfleckenkrankheit (Alternaria solani) ist eine schädliche Erkrankung von Tomatenpflanzen, die durch Pilze oder Bakterien verursacht wird und zu trockenen Flecken auf Blättern, Stängeln und Früchten führt. Erfahren Sie, wie Sie diese Krankheit erkennen, welche Ursachen sie hat und welche Maßnahmen zur Bekämpfung und Prävention effektiv sind. Zurück zu Tomatopedia Zurück zu Bilddiagnose dry spot disease Dry spot disease is characterized by the appearance of small, dry spots on the leaves, stems and fruits of tomato plants. These spots can grow and spread over time, causing a significant reduction in plant health and crop yield. Symptoms vary depending on the severity of the infection and the specific pathogen. Causes of Dry Spot Disease The main causes of dry spot disease in tomatoes are fungi and bacteria that occur in the environment or in the soil. The most common pathogens include: Fusarium oxysporum: A soil fungus that causes Fusarium wilt and is often found in tomato plants when they are grown in poorly aerated or heavily stressed soils. Alternaria solani: Also known as Alternaria leaf spot, this fungus causes typical spots on the leaves and can cause severe damage to the plants. Cladosporium spp.: These fungi are also responsible for the appearance of spots on the leaves and fruits. In addition to these fungal pathogens, bacterial infections such as leaf spot disease caused by Xanthomonas campestris can also cause similar symptoms. Symptoms of Dry Spot Disease Symptoms of dry spot often begin with small, watery spots on the leaves that quickly develop into dry, brown or black spots. These spots may have a yellowish edge and become larger and drier over time. Spots may also appear on the stems, often leading to weakening of the plant. Hard, dark spots may form on fruit, damaging the flesh. Measures to Combat Dry Spot Disease choose resistant varieties Some tomato varieties are more resistant to blight. Growing such varieties can significantly reduce the risk of infection. Proper watering Excessive moisture or irregular watering can promote the growth of pathogens. It is important to ensure consistent watering and avoid waterlogging. floor care Good soil aeration and avoiding over-fertilization can help reduce the risk of infections. Maintaining crop rotation and avoiding growing tomatoes in the same spot every year are also useful. cleanliness and hygiene Regularly cleaning gardens and removing diseased plant parts can prevent the spread of the disease. Disinfecting tools and equipment is also important. optimize growth conditions Ensuring that plants receive adequate sunlight, good air circulation and an appropriate temperature can help minimize the risk of infection. Difference between potassium deficiency and dry spot disease Based on the characteristic features in the photo above, it is safe to say that it is Dry Spot Disease (Alternaria solani). The following features support this diagnosis: Circular spots : The brown spots visible in the picture are irregularly shaped and sometimes have concentric circles, which is typical of dry spot disease. Spot distribution : The spots are not only on the edge, but are distributed over the entire leaf. Potassium deficiency is usually indicated by brown edges, while the inside of the leaf often remains green. Progression of the disease : In dry spot disease, the spots enlarge and the surrounding tissue turns yellow, which can also be seen in the picture. A potassium deficiency could show similar symptoms, especially at the edges of the leaves. However, typical symptoms such as discoloration along the leaf veins and the severe marginal necrosis that are more likely to occur with potassium deficiency are missing here. For a definitive diagnosis, it would be ideal to conduct a soil analysis to check nutrient levels or consult a plant laboratory that can test samples for fungal infections.

Why do some tomato seeds have brown spots or are brown? Tomato seeds may occasionally have brown spots, and this can be due to a variety of reasons: Natural variation : Some tomato varieties naturally produce seeds with brown spots or patches of different colors. These spots can be anchored in the plant's DNA and are part of the genetic variation within the species. Diseases : Tomato plants can be affected by various diseases that can affect the seeds. When a plant is diseased, the seeds obtained from that plant may have brown spots or other abnormalities. Unfavorable growing conditions : To obtain high-quality seeds, tomato plants must grow under ideal conditions. If the plants are exposed to unfavorable weather conditions or stressors such as inadequate irrigation, large temperature fluctuations, or nutrient deficiencies, the seeds may exhibit quality problems, including brown spots. Lack of drying or storage : After harvesting, tomato seeds must be thoroughly dried and stored correctly. If not done properly, the seeds can rot or become affected by mold, which can result in brown spots. It is important to note that brown spots on tomato seeds are not necessarily a sign of poor quality. Brown spots on tomato seeds are not necessarily a sign of poor quality. Zurück zur Übersicht

It was an uplifting moment when I harvested the juicy, golden yellow fruit. She was literally beaming on my hand. It was truly remarkable how early this variety ripened. The plant Foliage like from another world The breathtaking foliage of this special tomato variety is noticeable at first glance. The leaves are deep green and their shape is very reminiscent of the leaves of potato plants. But instead of sloping upward, these leaves grow downward, almost like curtains protecting the fruit beneath. This unusual leaf pattern gives the plant a distinctive look and makes it an eye-catcher in the garden. A narrow growth with a big impact The Siberian Yellow Heart is also characterized by its narrow growth. It grows upright and compact, making it an ideal choice for small gardens or growing in pots and containers. When grown as a single shoot, the plant can produce amazing yields. This is a great option for gardeners with limited space who still want to harvest high-quality tomatoes. Stable support for magnificent fruits An important tip for growing this tomato variety is to use a sturdy support structure. The fruits of this plant can be quite heavy and large. Sometimes there are even four fruits on one panicle! To prevent the branches from breaking or the plant from falling over, it is advisable to use a suitable support, cages or even tie them up. This way you can ensure that the tomato plants thrive safely and produce an impressive harvest. Space-saving and productive Due to its narrow growth and the ability to grow as a single shoot, this tomato variety is extremely space-saving. This means that many of these plants can be grown in limited space. It is therefore perfect for balconies, terraces or small vegetable gardens. Despite its compact growth, you can harvest an amazing amount of fruit from this tomato variety. The key to success: simple care and clever fertilization One of the reasons for my success in raising the "Siberian Yellow Heart" was the uncomplicated care. This variety is easy to grow. However, I made sure it received enough nutrients by using sheep's wool and crushed eggshells as natural fertilizer. Later in the season I added organic liquid fertilizer to ensure my plants were getting everything they needed. The fruit and the taste In the fascinating world of tomato varieties, there are some that stand out for their extraordinary appearance and even more impressive taste. One such variety is the "Siberian Yellow Heart". Welcome, Siberian Yellow Heart The Siberian Yellow Heart tomato is undoubtedly one of the most unusual varieties the tomato world has to offer. Its fruits are heart-shaped and shine a bright orange when fully ripe. This color alone makes them an asset to any garden, but it's their flavor that really stands out. A fruity delight The taste of the Siberian Yellow Heart tomato is extremely fruity. With every bite a great aroma unfolds that delights the palate.

Tomato cultivation A short guide from start to finish Growing tomatoes can be a rewarding experience, and there are a few steps to keep in mind to grow healthy tomato plants. Here is a step-by-step guide from sowing to harvesting - also available to download Download PDF guide Tomato Growing Guide 1. Selection of tomato varieties Tomato varieties should be chosen that are suitable for your climate. Please inform yourself beforehand whether you prefer determinate or indeterminate tomatoes (explanation - click here) . The types of tomatoes vary depending on the space available. You can find an overview here: Download overview 2. Sow seeds You can start sowing the seeds about 6-8 weeks before the last expected frost in your region. This is usually around early to mid-March. Sowing earlier does not really give you a head start on the harvest later. Procedure: see step-by-step sowing instructions. Download sowing instructions 3. Care of seedlings When the seedlings have reached a height of about 5 cm, they are carefully transplanted into larger pots or directly into the garden if there is no longer any danger of frost. Make sure there is enough light and keep the soil evenly moist. See also the sowing instructions under point 2. 4. Preparing the garden soil Starting in autumn/spring. Loosen the soil and remove weeds. Mix compost or well-rotted manure into the soil to improve the nutrients in the soil. 5. Planting Only plant the plants in the bed after the last frost. This is usually after the Ice Saints, i.e. after May 15th. Planting distance about 60 cm to 90 cm in rows and about 90 cm to 120 cm between rows. 6. Irrigation Keep the soil evenly moist, but definitely avoid waterlogging. The best times to water are early in the morning or late in the evening. 7. Fertilize More information Plants should be fertilized during the growing season with a balanced fertilizer rich in nitrogen, phosphorus and potassium. You can find detailed information about fertilizer here: 8. Mulch Mulch the soil around the plants with straw or other organic material. This will help retain moisture and suppress weeds, as well as increase soil fertility. Here are some commonly used organic mulching materials: Straw : Straw is a popular mulching material made from dried stems of cereal crops such as wheat, barley or oats. It is lightweight and easy to spread. Leaves : Fall leaves that have fallen from trees can be shredded and used as mulch. It is an inexpensive option and provides good cover. Wood chips : Made from shredded wood, wood chips or bark mulch last longer than some other mulching materials and are especially useful for suppressing weeds. Compost : Mature compost is an excellent way to enrich soil with nutrients. It can be used as mulch to encourage soil life and improve soil structure. Hay : Hay is similar to straw, but often contains seeds from grass plants that can cause weed problems later. Grass clippings : Freshly cut grass clippings can be used as mulch, but are most effective if dried first to prevent heat damage to plants. Coffee grounds : Coffee grounds are rich in nitrogen and make a good mulch for nitrogen-loving plants like tomatoes. Corn cobs : Dried corn cobs can be chopped up and used as mulch. They are especially useful for suppressing weeds. Ground leaves : The leaves can be shredded with a chipper and then used as mulch. Wood chips : Wood chips from thicker branches or pieces of wood can be used as mulch, but they are slower to decompose and should not be incorporated into the soil in large quantities. Paper or cardboard : Shredded newspaper, cardboard or paperboard can be used as a temporary mulch under a layer of other mulching materials to smother weeds. Choosing the best organic mulch material depends on the specific needs and plants in the garden. One can also use a combination of different types of mulch to achieve the desired results. Care should be taken to apply the mulch in a layer thick enough to achieve the desired benefits. 9. Supports There are several ways to support tomato plants to help them grow and produce fruit and to protect the plants from disease. Choosing the best method depends on the tomato variety, available space, climatic conditions and personal preferences. It is important that the chosen method provides sufficient support and enables the plants to be cared for and the fruits to be harvested. Some common methods are listed here: Tomato cages : Tomato cages are cage-shaped metal or wire mesh structures that are placed around the tomato plants. They provide support by surrounding the plants and preventing them from falling or spreading. They are easy to install and ideal for smaller tomato varieties. Rods : Individual poles or stakes are placed next to each tomato plant. The plants are then tied to the poles with string or rubber bands as they grow. This method works well for larger tomato varieties and requires regular care to keep the plants upright. Trellis or trellis: Trellis or trellis is often a latticework of wood or wire that is stretched horizontally across rows of tomato plants. The plants are directed onto the trellis or trellis and allowed to grow along the structure. This method saves space and makes harvesting easier. Tomato strings : In this method, the tomato plants are attached to vertical strings or wires that are attached to a sturdy frame or wall. The plants are then pulled up along the strings, saving space and promoting good air circulation. Hanging baskets : For bush tomatoes or hanging tomato varieties, you can grow tomatoes in hanging baskets. This method is particularly space-saving and can work well in small gardens or on balconies. Natural supports : Some gardeners use natural supports such as twigs, branches or bamboo poles to support their tomato plants. These are simply stuck into the ground and the tomato plants are tied to them. Combined methods : It is also possible to combine the above methods to optimize the stability and growth of tomato plants. 10. Protection against diseases and pests Look for signs of disease and pests and take appropriate control measures, such as removing diseased leaves or using biological agents when necessary. There are various biological agents and methods that can help keep tomato plants healthy such as: B. Crop rotation : Good crop rotation is crucial to prevent the spread of diseases and pests. Tomato plants should not be planted in the same location year after year. You should change the growing area regularly and try to grow other plants in between. Healthy Earth : Healthy soil is the key to healthy plants. Garden soil can be improved by adding compost and other organic materials. This also increases soil fertility. Mulch : Mulching around tomato plants with organic materials such as straw or wood chips helps retain moisture, suppress weeds and protect the soil from extreme temperatures. Water correctly : Tomatoes require regular but not excessive watering. Care should be taken to water the plants at the base and not the leaves to prevent the spread of fungal diseases. Choose disease-resistant varieties : When choosing tomato varieties, preference should be given to those varieties that are resistant to common diseases such as tomato mosaic virus, brown rot and late blight. This is especially important if the tomato plants are planted outdoors without a roof. Encourage natural enemy insects : Certain beneficial insects such as ladybugs and parasitic wasps are natural enemies of pests. Their populations can be encouraged by creating suitable plants and habitats for them in the garden. Handwork : Inspect tomato plants regularly for signs of disease or pests. If problems are identified early, you can react more quickly and minimize damage. Compost tea : Spraying tomato plants with homemade compost tea can help promote plant health and ward off disease.Click HERE and download instructions. Biological pest control : If pests are a problem, resort to biological pesticides such as neem oil or Bacillus thuringiensis (BT). These are less harmful to beneficial insects and the environment compared to chemical pesticides. Copper sprays : Copper sprays can help prevent fungal diseases such as brown rot and late blight. However, they should be used sparingly and according to instructions. It is important to note that a combination of these methods is often most effective. Organic farming practices promote soil health and minimize the need for chemical pesticides and fertilizers, resulting in healthier tomato plants. 11. Harvesting Tomatoes can be harvested 60 to 85 days after sowing, depending on the variety and climatic conditions. Only harvest fully ripe tomatoes. With careful care and attention, tomato plants should produce healthy fruits. It is important to remember that the local Climate and the specific conditions of your own garden can have an influence on success! Therefore, the cultivation methods should be adjusted accordingly.

Willst du wissen, wie oft du Tomaten düngen solltest? Auf dieser Seite erfährst du, welche Düngemethoden am besten für Tomaten geeignet sind und wie oft du sie düngen solltest.

Erfahre, welche Nährstoffe wichtig sind und wie du sie am besten zuführst, um eine reiche Ernte zu erzielen. Zurück zur Übersicht 22. How often should you fertilize tomato plants? The frequency with which tomato plants should be fertilized depends on several factors, including the fertilizer used, the soil in which the tomatoes are growing, and the growth stage of the plants.The fertilization needs of tomato plants can vary from season to season, and it is important to be flexible to respond to specific conditions in the garden. Basic fertilization : Before tomato plants are even planted in the ground, the soil should be well prepared by incorporating organic fertilizer (green waste, horn shavings, manure, algae extracts, etc.) or compost. This ensures a solid basic supply of nutrients. Organic fertilizers also have the advantage of providing slow-release nutrients that are available over a longer period of time. They also promote soil structure and soil life and help preserve the environment as they are generally more environmentally friendly than synthetic fertilizers. Long-term fertilizer : Slow-release fertilizers that release nutrients over a longer period of time can also be used. These may only need to be added once at the start of the season. These include, for example: B. Zeolite (mineral that can store nutrients in the soil and then release them to plants as needed), algae extracts, sheep's wool, sheep's wool pellets, compost or long-term fertilizer sticks. liquid fertilizer : If liquid fertilizer is used, you can start fertilizing the tomatoes about 2 to 4 weeks after planting. Then pay attention to the instructions for use on the packaging. growth phase : The fertilizer needs of tomato plants change throughout their life cycle. During the growth phase, when plants develop many leaves and shoots, they need more nitrogen. During fruit formation, they require more phosphorus and potassium. frequency : As a rule, it is better to fertilize more often with a weaker fertilizer solution rather than fertilize less often with a strong solution. This prevents overfertilization and the risk of nutrient burn. observation : It is important to observe the plants carefully. If any signs of nutrient deficiency are noticed, such as yellow leaves, slow development or poor fruit production, fertilizer may need to be applied more often. Soil testing : It is also helpful to conduct a soil test to determine the exact nutrient needs of tomato plants. This can help with the correct selection and dosage of fertilizers. It's also important to note that too much fertilizer can be harmful, so a conservative approach is often safer. Too much fertilizer can also be harmful, so a conservative approach is often better.

TheLate blight , translated from LatinPhytophthora infestans , is afungal disease , which particularly affects tomato and potato plants. This harmful fungus, which belongs to the egg mushroom species, has proven to be one of the most feared pathogens in agriculture. The term "late blight" describes the effects of the fungal attack on both types of plants: in potatoes, the infection leads to rapid decomposition of the tubers, while in tomatoes the disease affects the herbaceous foliage and fruits. Phytophthora infestans spreads preferentially under damp conditions Conditions and inwarm environments out of. The fungal spores thrive in a high humidity environment and spread quickly, causing devastating damage to plants. The typical signs of infestation are dark, moist spots on the leaves of the plants. This leads to wilting of leaves and decomposition of plant parts. The disease can spread quickly and, in the worst case, lead to the complete destruction of the plants. To minimize the spread of Phytophthora infestans, preventative measures are important. This includes growing resistant varieties, good ventilation, appropriate planting spacing, and early removal and proper disposal of infected plants. Combating this fungal disease is a challenge, but through a combination of various preventive measures and, if necessary, the use of biological preparations, attempts can be made to minimize the effects of late blight and reduce crop losses.

Braune Ränder an Tomatenblättern, die hauptsächlich an den unteren Blättern auftreten, sind ein typisches Anzeichen für Kalium-Mangel. Die Symptome sehen auf den ersten Blick dramatisch aus, sind aber eindeutig zuzuordnen und lassen sich gezielt beheben. Back to Tomatopedia Back to image diagnosis Recognizing and correcting potassium deficiency in tomatoes Brown edges on tomato leaves, mainly appearing on the lower leaves, are a typical sign of potassium deficiency. The symptoms may look dramatic at first glance, but they are clearly identifiable and can be addressed in a targeted way. Typical symptoms of potassium deficiency in tomatoes: Yellowish to brown discoloration along the leaf edges Leaf margins appear scorched or dry Necrosis begins at the edges and gradually moves inward Leaf veins remain green for a long time, while the tissue between them discolors first Symptoms usually appear first on older, lower leaves The deficiency develops gradually. If the underlying causes are not corrected, it can lead to stunted growth, poor fruit development, or fruit cracking. Causes of potassium deficiency Imbalance in nutrient supply, e.g. too much nitrogen and too little potassium Depleted soils or nutrient-poor potting substrate Heavy-feeding varieties or a high fruit load Irregular watering, which disrupts nutrient uptake In container growing: limited root space = faster nutrient depletion Potassium is a mobile nutrient that the plant redistributes from older leaves to younger parts when it is in short supply. This is why symptoms first appear on the lower leaves. Corrective measures for potassium deficiency Remove damaged leaves – they will not recover Apply a potassium-rich liquid fertilizer (e.g. tomato fertilizer with an NPK ratio of 6-3-10 or similar) Alternatively: comfrey liquid manure or wood ash (use sparingly) as natural potassium sources Water regularly and evenly, avoiding waterlogging Avoid excessive nitrogen fertilization – maintain a balanced nutrient ratio Existing damage will remain visible, but plant growth should stabilize. New leaves will then emerge healthy again. Potassium deficiency is not uncommon in tomatoes—especially under heavy fruit load or when grown in containers. The symptoms are clear: brownish leaf edges on older leaves. If addressed in time, the deficiency can be easily corrected without affecting the harvest. Back to Tomatopedia Back to image diagnosis

Wenn Tomatenblüten vor dem Fruchtansatz abfallen, steckt in den meisten Fällen ein vermeidbarer Kulturfehler dahinter. Der Blütenabwurf tritt häufig beim ersten Blütenstand auf und ist ein frühes Warnsignal der Pflanze, dass äußere Bedingungen nicht passen. Back to Tomatopedia Back to image diagnosis Blossom drop in tomatoes When tomato blossoms fall off before fruit set, in most cases this is due to avoidable cultivation errors. Blossom drop often occurs on the first flower cluster and is an early warning signal from the plant that environmental conditions are not suitable. Blossom drop – what exactly happens? Tomato plants produce bisexual flowers that are generally capable of self-pollination. However, if pollination is unsuccessful or the plant is under stress, it actively detaches from the affected flowers—the fruit does not develop. Instead of investing energy into a fruit that is unlikely to succeed, the plant drops the flower cluster. Possible causes of blossom drop Lack of pollination In protected cultivation (e.g. polytunnels, greenhouses), wind movement and insect activity are often missing. Without vibrations, the pollen remains in the anthers and the stigma is not pollinated. Temperature stress Temperatures below 12 °C or above 30 °C cause physiological stress. The plant aborts reproduction—flowers are the first to be sacrificed. Nutrient imbalance An excess of nitrogen promotes vegetative growth but inhibits the generative phase. Instead of fruit formation, the plant mainly produces leaf mass. Unstable water supply Strong fluctuations between drought and excessive moisture disrupt the plant’s water balance. In response to this stress, it drops unpollinated flowers. Variety-specific susceptibility Some varieties are more sensitive to unfavourable conditions, especially when flowering begins too early on still weakly developed plants. Plant overload If the plant has already set many fruits or is under continuous stress, it may no longer be able to supply all developing fruit. In such cases, it selectively aborts new flowers to prioritise existing fruits with nutrients. Practical solutions Gently shake flowers daily, especially in protected cultivation Ensure stable temperatures and good ventilation From the start of flowering, use low-nitrogen but potassium-rich fertilisation Water regularly and appropriately – avoid waterlogging If early flowering occurs on weak plants: consider removing the first flower cluster Blossom drop is not a serious problem, but rather an indication of unbalanced growing conditions. If the causes are identified and corrected in time, the plant will usually continue to develop normally—with successful fruit set on the subsequent flower clusters.

Harte Schalen bei Tomaten entstehen oft durch Hitze, ungleichmäßige Bewässerung, Nährstoffmangel oder Sorteneigenschaften. Regelmäßige Pflege, gezielte Bewässerung, Nährstoffzufuhr und der richtige Hitzeschutz helfen, das Problem zu vermeiden. Erfahre die häufigsten Ursachen und einfache Lösungen, sowie praktische Tipps für eine erfolgreiche Ernte! Zurück zur Übersicht Warum Tomaten manchmal eine harte Schale entwickeln und was man dagegen tun kann Tomaten sind in heimischen Gärten und auf Balkonen besonders beliebt, doch sie stehen manchmal vor Herausforderungen. Eine davon ist die Bildung einer harten Schale, die den Genuss und die Verarbeitung der Früchte erschweren kann. Dieses Phänomen tritt häufiger auf, als man denkt, und kann auf verschiedene Ursachen zurückgeführt werden. Ursachen für harte Tomatenschalen Die Bildung einer harten Schale bei Tomaten hat mehrere mögliche Gründe, die oft miteinander zusammenhängen: Witterungsbedingungen Heiße Temperaturen und eine hohe Sonneneinstrahlung fördern die Verdickung der Fruchtschale. Die Pflanze versucht, sich vor Feuchtigkeitsverlust zu schützen, indem sie eine dickere, widerstandsfähigere Haut ausbildet. Ungleichmäßige Bewässerung Schwankungen in der Wasserzufuhr – von Trockenheit bis zu plötzlichem Starkregen oder übermäßigem Gießen – können dazu führen, dass die Schale der Frucht sich verhärtet. Die Pflanze versucht, durch die dickere Schale innere Schäden zu kompensieren. Sortenspezifische Eigenschaften Manche Tomatensorten sind genetisch bedingt dickerhäutig. Besonders haltbare Sorten, die für den Transport oder die Lagerung gezüchtet wurden, neigen zu härteren Schalen. Nährstoffmangel Ein unausgewogenes Nährstoffangebot, insbesondere ein Mangel an Kalium und Magnesium, kann die Fruchtentwicklung beeinträchtigen. Eine dickere Schale ist oft eine Reaktion auf diese Stresssituation. Pflanzengesundheit Pflanzen, die unter Stress durch Krankheiten, Schädlinge oder andere Umweltfaktoren leiden, bilden häufiger harte Schalen, da sie ihre Ressourcen zur Selbstverteidigung umverteilen. Maßnahmen gegen harte Schalen Um die Bildung von harten Schalen bei Tomaten zu vermeiden, können folgende Maßnahmen helfen: Ausgewogene Bewässerung Eine regelmäßige und gleichmäßige Wasserversorgung ist entscheidend. Die Erde sollte stets leicht feucht sein, aber keine Staunässe aufweisen. Mulchen kann helfen, die Feuchtigkeit im Boden zu halten. Hitzeschutz Bei starker Sonneneinstrahlung sollten die Pflanzen schattiert werden, zum Beispiel mit einem Sonnensegel oder Vlies. Dies schützt nicht nur die Früchte, sondern auch die Pflanze insgesamt. Richtige Sortenwahl Wenn harte Schalen ein wiederkehrendes Problem sind, sollte auf Sorten zurückgegriffen werden, die für zarte Schalen bekannt sind. Alte Sorten wie Tigerella oder Butter Apple sind oft eine gute Wahl. Ausreichende Nährstoffversorgung Kalium- und magnesiumreiche Dünger fördern eine gesunde Fruchtentwicklung. Kompost, Holzasche oder ein spezieller Tomatendünger sind dafür gut geeignet. Regelmäßige Kontrolle der Pflanzen Gesunde Pflanzen sind widerstandsfähiger. Krankheiten und Schädlinge sollten frühzeitig erkannt und bekämpft werden. Eine gute Belüftung und der richtige Pflanzabstand fördern zudem die Gesundheit. Harte Tomatenschalen können das Genusserlebnis trüben, sind jedoch meist auf Umwelt- und Pflegebedingungen zurückzuführen. Mit der richtigen Sortenwahl, angepasster Bewässerung und einer ausgewogenen Düngung lassen sich viele Probleme vermeiden. Zurück zur Übersicht

Interessierst du dich dafür, wie Tomaten bestäubt werden? Auf dieser Seite erfährst du, wie die Bestäubung bei Tomatenpflanzen funktioniert. Entdecke den Prozess der natürlichen Bestäubung und die Rolle von Bienen und anderen Bestäubern. Erfahre, wie die Übertragung von Pollen zu Fruchtansatz und reifen Tomaten führt. Tauche in die faszinierende Welt der Bestäubung ein, um zu verstehen, wie du diesen Prozess unterstützen und eine reichhaltige Ernte erzielen kannst. Zurück zur Übersicht Wie verläuft der Bestäubungsprozess bei Tomatenblüten? Die Tomate ist eine bemerkenswerte Pflanze, die in der Lage ist , sich selbst zu befruchten , wodurch sie nicht unbedingt auf Insekten angewiesen ist, um Früchte zu bilden. Die Bestäubung der Tomatenblüten kann auf drei verschiedenen Wegen erfolgen. Zum einen kann sie durch Wind erfolgen, der die Pollen zwischen den Blüten transportiert. Ein weiterer Weg ist die Bestäubung durch Insekten , die durch das Saugen an der Blüte Vibrationen verursachen und so zur Befruchtung beitragen. Zudem kann auch das Schütteln der Pflanze durch den Gärtner oder die Gärtnerin zur Bestäubung beitragen. In Situationen, in denen Tomatenpflanzen an einem geschützten Ort stehen, beispielsweise an einem windstillen Standort mit wenig Insektenflug, kann man durch gelegentliches Schütteln der Pflanze zur Bestäubung beitragen. Die Blüten können dadurch effektiver befruchtet werden. Das Schütteln der Pflanze unterstützt den Prozess der Bestäubung und trägt dazu bei, dass sich mehr Früchte entwickeln, was die Erntemenge steigern kann. Zurück zur Übersicht

Tauche ein in die Welt der Tomatenpflege und lerne, wie du durch diese Praxis deine Pflanzen optimal unterstützen und pflegen kannst." Zurück zur Übersicht 9. What does culling mean for tomatoes and which varieties are culled? "Ausgeizen " ist ein gärtnerischer Begriff, der das Entfernen der Seitentriebe einer Pflanze bezeichnet. Dieser Vorgang wird insbesondere bei Stabtomatenpflanzen angewendet, um sicherzustellen, dass die Pflanze ihre gesamte Energie in die Haupttriebe und die Entwicklung ihrer Früchte steckt. Durch das Ausgeizen wird erreicht, dass die Früchte schneller und in der Regel von besserer Qualität reifen. Diese Praxis wird in der Regel ausschließlich bei Stabtomaten angewendet. Die Haupttriebe werden priorisiert, indem die Seitentriebe entfernt werden. Auf diese Weise konzentriert die Pflanze ihre Ressourcen auf die Haupttriebe, was zu einer besseren Fruchtbildung führt. Im Gegensatz dazu ist es bei Buschtomaten nicht erforderlich sie auszugeizen. Bei diesen Pflanzen ist es nicht notwendig, die Seitentriebe zu entfernen, da sie in ihrer natürlichen Wuchsform belassen werden können. Buschtomaten haben eine kompaktere Wuchsform, und das Wachstum ihrer Seitentriebe beeinflusst in der Regel nicht die Fruchtbildung oder die Pflanzengesundheit. Daher dürfen Buschtomaten in der Regel einfach in ihrem natürlichen Wuchs wachsen, ohne dass ein Ausgeizen erforderlich ist. Geiztrieb einer Tomate Zurück zur Übersicht

Tauche ein in meine Welt und erhalte Einblicke in meine Erfahrungen, Kenntnisse und Interessen. Erfahre, was mich antreibt und was mich einzigartig macht. Diese Seite gibt dir die Gelegenheit, mich besser kennenzulernen. About me and how I came to tomatoes... My passion for gardens and tomatoes: A look into my green paradise Since 2021, I have been able to proudly call myself a garden owner, and the two separate gardens in our residential area have enriched my life in many ways. My gardening adventure began with one simple step, from green lawn to the earthy diversity of a blooming garden. The transition from the meadow to the garden was a transformation that took my relationship with nature to a whole new level. Instead of just being an observer, I became the designer of a green oasis in which plants and animals live in harmony with one another. Sustainability and nature conservation were my focus right from the start. In 2021 I discovered my passion for tomatoes. Growing this diverse fruit became a matter close to my heart. I experimented with different varieties, learned about the needs of these plants and shared the joy of the first ripe fruits with my family and neighborhood. The tomatoes became symbols of my journey as a gardener. Membership in the “Association for the Conservation of Crop Diversity” from 2022 was a logical step for me. In this committed association I found like-minded people who are committed to preserving old varieties and biological diversity in our gardens. Together we are committed to preserving the traditions of seed protection. For me, the issue of seeds is of central importance and I am committed to ensuring that there is no place for harmful chemicals in my garden. My goal is to garden in harmony with nature rather than against it. This means I rely on natural methods to repel pests and promote soil health. This way I can ensure that my gardens are not only beneficial for me, but also for the environment. A particular joy for me are the three seed exchange boxes that I was able to set up in three different locations. These serve as a platform for the community to share seeds and promote diversity in our gardens. Everyone can exchange seeds here and thus make their own contribution to preserving crop diversity. As a garden owner dedicated to nature, I have begun an exciting journey. My goal is to preserve the beauty of nature while producing delicious harvests. My garden is more than just a place to relax - it is a place where I garden in harmony with nature and celebrate the wonders of life in all its forms. I'm very happy that you like tomatoes on my homepage! Stop by to experience diversity and wish you an inspiring time full of gardening joy! Your Sabine My story - how it all began... It started small. With an order of 10 types of tomatoes in a surprise letter. Some time ago I had no idea what wonderful variety the world of tomatoes would still offer me... For me, tomatoes have become much more than just a simple vegetable. First of all, it is the variety of tomato varieties that excites me. From small cherry tomatoes to large beefsteak tomatoes, there are countless variations in shape, color and taste. Each variety has its own peculiarities and characteristics. It's exciting to try out the different varieties and get to know their individual characteristics. Another reason I am so fascinated by tomatoes is their growing process. It is impressive to watch how a small seed grows into a powerful plant. It fills me with pride and joy to be able to actively experience this process. The taste of fresh, home-grown tomatoes is another reason why this topic fascinates me. There's nothing better than the sweet, juicy taste of a ripe tomato straight from your own garden. The aromas and nuances are incomparable and amaze me every time. It is a pleasure that I like to share with others and that always motivates me to grow new varieties and discover new taste experiences. In addition to all these reasons, I am also fascinated by the history and culture of the tomato. Originally from South America, it has spread throughout the world over the centuries and has become an integral part of the cuisine of many cultures. Tomatoes are a symbol of diversity, enjoyment and health. Overall, I am fascinated by the topic of tomatoes because of their diversity, their growing process, their challenges, their taste and their cultural significance. For me they are not just a type of vegetable, but a passion that inspires me again and again. The tomato is a small miracle of nature that inspires and motivates me to deal intensively with it.

The cultivation of Heinemann's anniversary begins On March 15, 2023 the time had finally come and I planted the seeds of Heinemann's anniversary in pots to grow them early. After a short time the first green seedlings appeared and the anticipation grew. Caring for the plants was very easy: regular watering and sufficient light (in my case special plant light) were all they needed. The Heinmanns anniversary grew best under a roof. The first signs of success On June 20th, just three months after planting the seeds, I could see the first small green tomatoes on the plants. It was amazing how quickly the plants developed and produced fruit. The plants looked healthy and very strong. I only had to support them shortly before they were ripe! The harvest time In mid-August the time had finally come: the first ripe tomatoes were ready to be harvested. The taste of Heinemann's anniversary was simply good. The tomatoes were juicy and had an intense aroma. They were perfect for salads, sauces and of course for fresh tomato sandwiches, but also for drying. A productive and long harvest season In total I had ten Heinemanns Anniversary plants in my garden, and they produced an impressive amount of tomatoes. The plants were so productive that I had plenty of tomatoes and was even able to can some tomatoes. The date of the last harvest will follow soon, It is currently the end of September and the plants are still full of lots of red and green tomatoes. The plant Compact but powerful One of the most striking features of Heinemann's Jubilee is its low stature. With a maximum height of around 70 cm, it is ideal for smaller gardens, terraces, raised beds and balconies. But don't let its size fool you - this plant is extremely powerful. Lush growth and low maintenance requirements Heinemann's Jubilee is characterized by its bushy growth. This means it produces lots of leaves that protect the fruit from the intense sun and reduce evaporation. Another advantage of this bushy growth is that no pruning is necessary. So you don't have to constantly remove side shoots to keep the plant in shape. Strong stems for heavy fruit The stems of Heinemann's Jubilee are so robust that they can easily bear the load of the numerous fruits. I was surprised at how many large tomatoes this small plant can produce. The need to tie or support the plant only arose when the fruits had reached an impressive size. Fruit and taste Of course, the quality of the fruit is crucial. Heinemann's anniversary does not disappoint in this respect. The aroma of Heinemann's anniversary One of the outstanding features of Heinemann's Anniversary is undoubtedly its intense aroma. This is fruity, sweet and has a slightly spicy note that makes every bite a culinary experience. The taste is reminiscent of sun-ripened tomatoes that have ripened on the windowsill all summer long. The texture of the fruit Heinemann's Jubilee is characterized not only by its excellent taste, but also by its perfect texture. The fruits are juicy and firm at the same time, making them an excellent choice for a variety of dishes. Whether you want to use them in salads, make salsa, dry them or simply enjoy them fresh, the texture of these tomatoes will impress you. The size of the fruit The fruits of Heinemann's anniversary are not huge. They are usually medium sized and weigh around 100 to 150 grams each. Harvest maturity and taste Another great feature of Heinemann's Jubilee is that the fruit is perfectly ripe when harvested. This means that they have already developed their full flavor and sweetness when you pick them. You don't have to wait for them to ripen, which is particularly advantageous if you want to enjoy them fresh. Order seeds here
