How to trim wampee trees? The natural tree shape of wampee is round-headed, and the pruning can refer to citrus fruit trees. The stem height is fixed at 1 m, so that 3~4 main branches are evenly distributed, and then side branches are drawn on them to form a round head shape. Branches that bear fruit that year can't bear fruit the next year. When harvesting, we should leave 1 ~2 buds at the base of fruiting branches for short cutting, so as to promote the axillary buds at the base to grow autumn shoots as fruiting branches in the next year. After harvesting, pruning is carried out from June 1 1 to February 65438 every year, and internal dead branches, shade branches, over-dense branches and pest branches are cut off.
