There are two reasons for pruning potted oranges reasonably. First, the pot is small, the soil is small, and the nutrients provided are limited, which can not meet the needs of citrus growth and must be pruned; Second, through pruning, the rational distribution of nutrients in the tree can be adjusted, so that limited nutrients can be supplied to buds and leaves to form more fruiting branches, thus achieving full flowering and fruiting branches. 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. Cut off strong branches and weak branches.
