After the young trees are cultivated and survive, they should be aired first. After 2 ~ 3 years, if the central main branches of the young trees grow vigorously, the trees should be pruned into a sparse trunk. If the central main branch of the young tree grows weakly within 3 years, pruning can be postponed appropriately until it grows up. However, if it does not grow into a central leading branch, it should be trimmed in a natural and gratifying shape.

For young trees with weak growth potential, the branch position is generally low, which will affect the determination of trunk height. At this time, you can cut off the branches from the base, leaving only one upright branch, let it continue to grow, and then carry out plastic pruning according to the situation two years later.

Young trees should be pruned mainly in summer, supplemented by winter pruning, and combined with winter and summer.
