Pruning and pruning methods for crabapple flower cultivation

Pruning and pruning is mainly to improve the lighting conditions inside the crown to form a beautiful tree shape. to improve the viewing value. Generally, pruning is carried out after the leaves fall and before budding in early spring to remove dead branches, diseased branches, and weak branches to keep the canopy dispersed and ventilated.

In order to promote vigorous flowering of plants, long branches should be shortened to reduce nutrient consumption for germination, so that the remaining axillary buds can obtain more nutrients and form more flowering and fruiting branches. Fruiting branches and middle branches do not need to be pruned.

During the growth period, if topping can be carried out in time and vegetative growth is restricted in the early stage, the effect will be more significant, especially for potted landscapes.
