Collaterals cannot be removed prematurely. When tomato collaterals are too small, the nutrients it produces are greater than the nutrients consumed, so it should not be removed at this time, especially when the leaves of the plant do not completely cover the ground. In order to make full use of the side branches to produce nutrition, it is advisable to remove the side branch with a length of about 5 cm. For the first branch of the lower part of the flower of the tomato, it should be removed as early as possible, and should be removed when the length is about 3 cm.
Collateral can not be too late. If the tomato side branches are removed too late and the collaterals are longer than 5 cm, they will compete with the main branch for nutrients and the growth will gradually exceed the main branch. Lateral branching and sparseness will also cause aging of the phloem of the lateral branch. Since the lateral branch and the phloem of the main branch are closely connected, the epidermis of the main branch is easily broken when the lateral branch is removed, which affects the growth of the tomato. In addition, when removing lateral branches of tomatoes, piles should not be left to prevent re-emergence of lateral branches from the same leaf.
