How to remove leaves from tomato plants? The latest leaf removal methods and precautions
Removing leaves from tomato plants not only improves the air circulation between plants and reduces the possibility of pests and diseases breeding, but also, by removing leaves affected by disease, reduces the spread of pathogens, and by removing old leaves, avoids unnecessary consumption of nutrients. So how should tomatoes have their leaves removed? What should be paid attention to? Let's take a look together.
1. Leaf removal methods
1. Old leaves
In the later stage of tomato growth, there are many aged leaves on the lower part of the plant. If these leaves are not removed in time, they may not only cause the plant to become diseased, but also consume the tomato's nutrients, causing unnecessary waste, so this kind of old leaf must be removed in time.
2. Thick, heavy leaves
Some tomato leaves are thick and heavy, and they will seriously affect the ventilation and light penetration of the tomatoes, so when removing leaves they can be removed together, but when removing leaves some technical issues must also be followed; it is not suitable to remove them too aggressively, otherwise the photosynthetic efficiency will drop severely, which is very unfavorable to tomato growth.
3. Bottom leaves
When the tomatoes are about to ripen, the leaves at the bottom and lower part of the tomato plant should be removed in time, as this can ensure the greatest possible ventilation and light penetration inside the greenhouse, and their presence would also compete with the fruit for water and nutrients during growth and development, affecting the later yield.
4. Yellowing leaves
When yellow leaves appear on tomatoes, they should also be removed in time, because these yellow leaves are very likely caused by infection with pests or diseases. If they are not removed in time, since the leaves may already carry pathogens, they will slowly infect other leaves, eventually causing the whole plant to wither and die, and the yield will naturally be affected as well. However, if the yellow leaves are caused by a lack of water or nutrients, they should appear one by one; this kind of yellow leaf only needs strengthened fertilizer and water management to return to normal, and does not need to be removed.
2. Precautions
When removing leaves, do not remove all the leaves at once; each time remove at most the bottom two leaves, and there must be an interval of more than 10 days between two leaf removals, so as to ensure the tomatoes grow vigorously. In addition, pay attention to the timing when removing leaves; leaves cannot be removed in the morning and evening. Generally, choose noon for leaf removal, because in the morning and evening there is dew on the leaves, and after the leaves are picked off, the wounds will become infected, while at noon the temperature is high, and after picking the leaves, the wounds will dry out quickly. Of course, after removing leaves, some pesticide can also be sprayed to prevent pathogens from taking the opportunity to invade.
