The effect of pruning cherimoya

There are few branches in the natural growth state, and the branches are easy to overgrow and the crown is messy. During the growing season, the hearts and leaves of the branches should be picked, which can control the growth length of the branches, promote sprouting of young shoots, and promote branching. In addition, through retraction and pruning, the germination of dormant buds in the old technology is also very strong.

Announcement pruning time

Announcement can be pruned once every spring in mid-March, when most of the deciduous branches have sprouted.

Methods for pruning custard apples

Keep the height of the custard apple trunk at 40-50cm, and trim the upper leaves to retain 3-4 main branches. When the main branch reaches 60 cm, it can be topped. After 30 days, when the leaves turn green and mature, you can remove the middle and upper leaves of each main branch and keep 2 leaves of each secondary branch. When the secondary branches grow to 35 cm, remove the hearts and wait until the leaves mature before removing them. This cycle repeats in turn. During the branching period, preparations should be made for branch thinning, leaving only one new shoot in each leaf axil, topping, and cutting off yellow leaves in time. Young trees can promote new shoots 4-5 times a year. During the growth period of custard apple, it is necessary to do a good job in picking the heart leaves. This can reduce the consumption of nutrients and make the latent buds grow faster. In addition, dead, old, diseased and weak branches can be pruned in time during the winter dormancy period to help them survive the winter better.

Precautions for pruning custard apples

The leaves of custard apples should be cut and picked in June to promote flowering in different periods. According to needs, flower pollination can be carried out in different months to adjust the fruit testing time and extend the fruit period from September to March of the following year.
