A common practice to control growth and improve fruit quality is deadheading tomato plants.
​
Pruning is a horticultural step in which the main shoot or tip of the plant is removed. This process is designed to limit the plant's uncontrolled height growth. Tomatoes have naturally strong growth potential, and removing the tips of the shoots will help prevent the plant from shooting up uncontrollably.
​
The main reason for deadheading is that a plant that grows too long and tall is not only more difficult to care for, but can also affect fruit production. If the tomato plant grows too large and out of control, it may invest more of its energy in growing new shoots and leaves instead of ripening the fruits it already has. The result could be that the fruits are smaller and less numerous.
​
By deadheading, the plant focuses its energy on the existing fruits and flowers. The plant therefore focuses more on the ripening and development of the existing fruits, resulting in higher quality and better utilization of resources.
​
However, topping is not a universal rule, but a practice that depends on various factors such as tomato variety, climate and individual growing goals. Some varieties may require less trimming than others.
​
Overall, topping your tomato plants can be a worthwhile measure to control growth, keep the plant healthy and ensure a bountiful harvest of high-quality fruit. It is advisable to learn about the specific needs of the tomato variety being grown and to consider your own garden conditions before beginning topping.
