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:
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.
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.
