In the early stage of eggplant, you should not pick the leaves on the branches too early. This is the key period of root growth, and more leaves are needed to make more nutrients for root growth. Remove diseased leaves and old leaves. In the process of eggplant growth, the leaves at the bottom will also age first, so if you want to pick the leaves of eggplant, you should give priority to picking the old leaves and sick leaves at the bottom of eggplant. The branches of eggplant are very neat after fruiting. Generally, it is only necessary to wipe off too many side branches near the ground below the root eggplant to avoid too many branches and leaves, which will affect ventilation and light transmission. In the rainy season, old yellow leaves and diseased leaves should be often knocked out to reduce falling flowers and fruit diseases.

If the new leaves at the top are not fully developed, it is not suitable for picking leaves at this time. Make sure that other leaves supply nutrients to the top. When the new leaves at the top are fully developed, we can consider removing some old leaves at the lower part and some old leaves on the weak branches that are not fruitful. Generally, varieties with tall plant types and vigorous growth are selected for greenhouse planting. Because of the pursuit of efficiency and yield, the planting density is generally high and is also limited by local conditions. According to personal planting habits and densities, there are unipolar, bipolar and tripolar.

In eggplant cultivation, when the density is high, which affects ventilation and light transmission, some old leaves can be picked properly to reduce the occurrence of cotton wilt and improve fruit color, but mature leaves cannot be picked, and too many leaves will directly affect the yield. Generally, eggplant does not need to pick leaves at the early stage of growth. Some leaves of eggplant should be removed, especially the leaves covered with eggplant fruit at the top, and it is best to remove some appropriately. Leaves should also be picked in stages, and the lower leaves should not be picked at one time, which is not conducive to the growth of the lower root system and the supply of nutrients in the upper part. Generally, when the eggplant grows to a diameter of about 4 cm, the old leaves below it can be removed. Generally, it is pruned by double branches. When the first branch diverges, both branches remain, one is strong and the other is weak. The effect is not particularly obvious at this time. When the second branch forks, only one strong branch is left, and the weak branch is knocked out.
