1. If you prune eggplant, you should prune the side branches below the eggplant, the weak branches and side plants of the stem, and the old leaves and diseased leaves. To facilitate ventilation and light transmission, it should be removed. Eggplant is a two-branch crop. Its growth is weak, so the branches at the base and side branches should be cut off in time, and some branches that are too dense should also be trimmed, so that eggplant can grow more vigorously.

2. It is best to prune the leaves of eggplant four or five times during the whole growth period, and don't prune too much at one time.

3. The pruning amount of eggplant leaves depends on the variety and weather. Generally, the number of eggplant plants with weak rameting ability is small, eggplant leaves are cut less in the early stage of growth, and plots with less fertilizer are cut less in drought.

4. For eggplant plants with normal growth and weak performance, you can first loosen the small fruits on the plants, leaving a few eggplant fruits with good growth, and then shrink where there are obvious strong buds under the position of "Simandou", cut off the weak branches, and focus on leaving a few strong buds to cultivate into fruiting branches.

5. For moderately weak eggplant plants, there are many fruits but small heads, and there are no strong axillary buds above the eggplant part, but there are healthy buds above and below the eggplant part. You can pick all the fruits on the plant first, and then retract them from the eggplant part, leaving strong buds of 1-2 at the bottom of the eggplant plant.

6. For eggplant plants with obvious dehydration and degreasing, they should be retracted from the branches of the two main branches. For those with severe weakness, they should be pruned from the same root to promote strong branches and fruits.

No matter what kind of eggplant pruning and leaf pruning, water and fertilizer should be combined after pruning to promote the growth of eggplant. After eggplant pruning, in order to prevent the pruning wound from being infected by germs, it is necessary to spray chemicals such as chlorothalonil in time for protection.

Be careful not to prune too many eggplants. For example, pruning leaves should be done in stages. Pruning of eggplant plants with weak branching ability should be done less, and pruning at the early stage of eggplant growth should be done less. Use sterilized sharp scissors when trimming. Pruning time is best in sunny days.
