Because the nutrition of blueberry is limited, it needs to be pruned reasonably to preserve the nutritional components of the plant and promote the better growth of blueberry.

Plastic pruning of potted blueberries;

Pruning period can be divided into winter pruning and summer pruning, strictly speaking, dormancy pruning and growing season pruning. Young trees that have just been planted need to cut off buds and too thin branches. For strong branches, it is generally necessary to prune them to varying degrees. In the first growing season of survival, cut as little or no as possible, and spread the crown and branches at the fastest speed.

When the first three young trees are pruned in winter, the weak branches, drooping branches, horizontal branches, cross branches, over-dense branches and overlapping branches in the crown are mainly thinned. You can cut off the bud at the top of the branch a little shorter. After germination in spring, some new shoots should be selectively erased as soon as possible to strengthen the growth potential of the retained new shoots.

After entering the full fruit stage, the crown size has basically reached the requirements, so we should start to control the further expansion of the crown and leave the limited space for more vigorous branches or branches. The principle is to remove the weak and retain the strong. In addition to weak branches, diseased branches, dead branches, cross branches and adjacent overlapping branches are also the objects to be refined.

The main pests and diseases of blueberry are scarab, scarab larva, grub, and common pests and diseases such as leaf chlorosis, leaf blight, fruit rot and leaf-eating moth. Good prevention and control can be avoided.
