Winter is the dormancy period of pomegranate tree. At this time, it stops growing and pruning will not cause damage. First, prune the big branches and keep only three main branches. The distance between them should be about 80-100cm, leaving a certain space for growth. Then prune the twigs. The upper and outer parts of the crown should be a little sparse. The inner bore branches may be slightly dense, but not overlapping. The fruiting branches with flower buds should be preserved. If there are too many, some twigs can be spared. In addition, 3 - 5 vegetative branches should be reserved for each fruiting branch.
Pomegranate trees begin to sprout in spring, and the pruning time should be before flowering, usually from April to May. At this time, pruning is mainly to adjust the ratio of fruiting branches and vegetative branches, which is controlled between 1:5 and 1:15. If there are too many fruit branches, the nutrient supply will be insufficient, resulting in a small fruit growth. In addition, it is necessary to release buds and flowers in time. Cut out the bell shaped flowers and the tube shaped flowers, and only keep the gourd shaped flowers.
Pomegranate trees begin to bear fruit in summer, and pruning is generally carried out from June to July. We need to cut off the smaller fruits so that the nutrients can be supplied centrally. The diseased fruits and insect fruits should also be cut off to prevent the spread of diseases and insect pests. In addition, appropriate thinning branches are needed to cut off dense branches and extra long branches, so as to ensure the internal ventilation and light transmission. If the main branch grows too close, you need to pull the branch properly to keep the distance between them at about 80-100cm.
Autumn is the stage of pomegranate fruit growth, so it should be pruned from August to October. Prune the branches so that the fruit can see the light and promote the growth of flower buds. At the same time, we also need to prune the roots, which can promote the growth of new roots, but also improve the cold resistance, which is conducive to winter.
