Latest tomato leaf pruning misconceptions, avoid these mistakes
Tomato is a vegetable well known to everyone, whether eaten raw or cooked it is especially delicious, and market demand is relatively high, so quite a lot of people grow it. When growing tomatoes, leaf pruning is often encountered, but many people prune leaves incorrectly. Let's take a look below.
1. Excessive leaf pruning
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 will cause insufficient photosynthetic products. The final result is that the fruit is small and deformed, and both yield and quality cannot improve. It will also cause tomatoes to compete with each other for nutrients, with roots and fruits competing with each other for nutrients, which is extremely detrimental to the growth and development of tomatoes.
2. Pruning leaves too early
There is a right time for pruning tomato leaves. The leaf age of tomato is generally 15-50 days, during which photosynthesis is relatively strong, so generally once leaves exceed 50 days they should be pruned in time. Do not prune leaves before 50 days, when the photosynthesis of the leaves is relatively strong. If 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 choice is to remove yellow leaves. In fact, this practice is not correct. Tomato leaves turn yellow for many reasons. For example, improper watering and fertilizing will cause leaves to turn yellow, or when the plant's root system is damaged, the leaves cannot absorb nutrients and will also turn yellow. When leaves turn yellow, you can spray Bihu solution to restore them, so that the leaves can return to normal leaf color, and there is no need to prune them.
4. Pruning insect-damaged leaves
When pruning leaves, besides 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 they have eaten, and in this way relatively many leaves are pruned, which is also inadvisable. For pests, chemical agents can be chosen for treatment. There is no need to remove all insect-damaged leaves, only the seriously damaged leaves need to be pruned.
5. Pruning shading leaves
Besides liking to prune yellow leaves and insect-damaged leaves, many friends also like to prune shading leaves. Many people think that if they are not pruned, it will affect fruit coloring. In fact, there is also no need to remove them all. You can adjust the temperature inside the greenhouse. Fruit not coloring is not because of the leaves.
