What are the common mistakes in tomato leaf pruning? These errors should be avoided

Tomato is a well-known vegetable; whether eaten raw or cooked, it is especially delicious, and market demand is relatively high, so many people grow it. When growing tomatoes, leaf pruning is often necessary, but many people prune leaves incorrectly. Let's take a look below.

1. Pruning too many leaves

When pruning tomato leaves, many people like to remove all the branches and leaves below the fruit. In fact, this practice is wrong. After all the leaves are removed, the tomato cannot carry out photosynthesis, which leads to insufficient photosynthetic products. The final result is small and deformed fruit, and both yield and quality cannot improve. It also causes the tomato plants to compete with each other for nutrients, with the roots and fruit competing for nutrients, which is extremely unfavorable to the growth and development of the tomato.

2. Pruning too early

Tomato leaf pruning has a timing. The photosynthesis of tomato leaves is generally relatively strong when the leaf age is within 15-50 days, so generally once the leaves exceed 50 days, they should be pruned promptly. Do not prune the leaves before 50 days, as at this time the leaves have relatively strong photosynthesis. If the leaves are pruned too early, the tomato will be unable to synthesize the nutrients needed for fruit growth and development, and as nutrient supply falls short of demand, the fruit will also stop developing.

3. Pruning as soon as leaves turn yellow

When many farmers choose leaves to prune, the first ones they choose to remove are the yellow leaves. In fact, this practice is not correct. Tomato leaves turn yellow for many reasons. For example, improper watering and fertilization can cause leaves to turn yellow, or the plant roots have been damaged, so the leaves cannot absorb nutrients and also turn yellow. When the leaves turn yellow, spraying a Bihu solution can restore them, so the leaves can return to their normal leaf color, and there is no need to prune them.

4. Removing insect-damaged leaves

When pruning leaves, in addition to removing all the yellow leaves they see, many people also remove all the leaves with insect holes. Especially when whiteflies and leafminers appear, they remove all the leaves that these pests have eaten, and in this way a relatively large number of leaves are removed, which is also not advisable. For pest damage, chemical pesticides can be chosen for treatment; there is no need to remove all the insect-damaged leaves, only the severely damaged leaves need to be removed.

5. Removing shading leaves

Besides liking to remove yellow leaves and insect-damaged leaves, many friends also like to remove shading leaves. Many people think that if they are not removed, it will affect fruit coloring. In fact, there is also no need to remove them all; you can adjust the temperature inside the greenhouse, and fruit not coloring is not because of the leaves.
