The following information comes from the conversation between uncle flower shop and flower shop group. I feel sorry for my lemon. The leaves are all dry. What should I do? How do you want it trimmed? Not suitable for indoor use. Shi Yi: Water it when it is dry. D: I'm standing there now, blowing him every day. Shi Yi: There are two reasons for pruning potted lemon trees: First, the pot is small, the soil is small, and the nutrients provided are limited, which cannot meet the growth needs of lemon trees and must be pruned. Second, through pruning, adjust the rational distribution of nutrients in the tree, so that limited nutrients can be supplied to buds and leaves, forming more fruiting branches and making flowers and fruits full of branches. Before the spring shoots of potted lemon trees germinate, intensity pruning must be carried out. One is dead branches, diseased branches, clustered branches, inward branches, cross branches, sprouting branches and so on. Must be removed. Weakly cut strong branches, leaving 4~5 full buds; Strong pruning leaves 2~3 buds on weak branches, so that each branch produces more robust spring shoots. After the spring shoots are full, in order to control their length, they can be lightly pruned and cut off 3~4 branches. When the new buds grow to 6-8 knots in the future, in order to induce more summer buds, it is necessary to lose heart. Water conservation before flowering: In order to prevent summer shoots from growing too vigorously, trees should accumulate nutrients and promote the formation of flower buds. Potted lemon trees should be watered before high temperature. Specifically, more than ten days before the arrival of the hot summer, the water supply to potted lemon trees gradually decreased; Water was cut off five days ago, the basin soil was exposed to the sun, a lot of water evaporated and the basin soil was dry; Due to the lack of water in roots, branches and leaves lose water, and leaves wither and curl. In order to prevent dehydration of leaves, water can be sprayed on the leaves in the morning and evening, or a small amount of water can be sprayed on the pot soil to keep the lemon tree dry, but its axillary buds expand day by day and the color of the buds turns from green to white. When most axillary buds turn from green to white, "withholding water" promotes the success of flowering. At this time, the water supply of potted lemon trees should be restored in time. [D]: OK, I'll go home and have a look. I will repair all the bad branches. Thanks to Shi Yi, D and others for their dialogue.
