Pomegranate trees can be divided into spring pruning and autumn pruning. When pruning in spring, we should prune dead branches and diseased branches to keep strong branches and crown shapes, which is conducive to promoting the effect of more new branches, more flowers and more fruits. When the seedlings are over 0.8m, they can be picked many times. When pruning in autumn, new branches and overgrown branches should be pruned to reduce nutrient consumption, increase ventilation and light transmission, and at the same time, small buds sprouting from roots should be pruned to promote flower bud differentiation.

Matters needing attention in pomegranate tree pruning:

1. In the second year of young tree growth, each tree leaves about 3 strong branches as the cultivation trunk, and all other branches are sparse. In the future, we should always pay attention to removing the buds and shoots that grow near the ground. In the third year, the pomegranate tree was shaped, and all the branchlets growing below 0.8 meters above the ground were thinned and cut off, leaving about 6 stout main branches on each trunk to make the crown round.

2. Spring, dead branches, diseased branches, weak branches, etc. During the wintering period, it should be cut off to keep strong branches and crown shapes, which is conducive to promoting the effect of more new branches, more flowers and more fruits. When the seedlings grow to more than 0.8 cm, they can start to pick the core many times to promote the branches to reach the full crown width.

3. After planting for 5 years, the crown of the first-bearing tree expands rapidly and has many branches. At this time, if pruning and management measures are reasonable, the output will increase rapidly. Measures such as thinning, twisting and pulling are taken to transform the overgrowth technology and tillering branches that affect the growth of backbone branches into large and medium-sized fruiting branches, so as to achieve the purpose of good flowers and good fruits.

4. Cut off budding new branches, clustered branches and diseased branches in autumn, so as to reduce nutrient consumption, increase ventilation and light transmission, promote fruit growth, and at the same time cut off budding buds at roots to promote flower bud differentiation.

5, root pruning, combined with deep ploughing and basal fertilizer application in autumn, digging a 60cm deep annular ditch at the vertical projection of the original crown, shoveling out all the roots in the ditch, and applying organic fertilizer mainly containing phosphate fertilizer to promote the generation of a large number of new roots, so as to achieve the purpose of restoring tree potential.
