Apple tree pruning should be carried out at appropriate times throughout the seasons.

Before germination in spring (early to mid-March), carve the buds of small trees without fruit to promote branching; for mature trees, prune again before flowering to adjust the number of flower buds; after germination Wipe out sprouts near the cut to save nutrients.

Perform 1-2 summer prunings in the summer (May-August) to remove upright branches, overly dense branches, diseased and insect-infested branches, etc., widen the angle of the main branches, and improve the lighting in the canopy. , promote flower bud differentiation.

Carry out autumn pruning in autumn (September-October) to remove large branches that block light, strong branches on the back, overly dense branches, diseased and insect-infested branches, etc., to improve the lighting in the canopy.

Winter pruning is carried out after the leaves fall in winter (late November to mid-to-late February). According to different tree species and planting densities, appropriate tree shapes are selected, and pruning is done reasonably to achieve the correct shaping results. .
