How to prune and cultivate orange trees after the Spring Festival

The spring shoots of potted oranges must be pruned intensively before they germinate. First of all, we should remove dead branches, diseased branches, clustered branches, inward branches, cross branches and sprouting branches. Weakly cut strong branches, leaving 4 or 5 full buds; Strong pruning of weak branches leaves 2 or 3 buds, so that each branch can grow stronger spring shoots. After the spring shoots are fully grown, in order to control their imaginary length, they can be lightly cut and 3 or 4 branches can be cut off. When the new shoots grow to 6 ~ 8 knots, it is necessary to remove the heart to induce more summer shoots.

In order to prevent the summer shoots from growing too vigorously, at the same time, let the trees accumulate nutrients and promote the formation of buds, potted oranges should be "watered" before summer. The specific method is to gradually reduce the water supply to potted oranges more than ten days before the hot summer; In the first 5 days, the water was stopped, 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 the leaves from dehydration, water can be sprayed on the leaves in the morning and evening, and a small amount of water can be sprayed on the pot soil at the same time, so that the axillary buds of oranges expand day by day under the condition of drought and not dying, and the color of the buds turns from green to white. When most axillary buds turn from green to white, "withholding water" will succeed in promoting flowers. At this time, it is necessary to restore the water supply of potted oranges in time.
