When the seedlings grow to conform to the pruning model, the top branches should be pruned, knotted and cored, so as to inhibit the growth of the upper branches, and the tree potential nutrients will be concentrated and transported to the uninjured branches below to make them grow thicker.
According to the shape design, if the branches need to grow thick, they will gain growth advantages and grow thick quickly without pruning, topping, coring and picking leaves.
If pruning is carried out at the same time, and the budding power advantage of the whole tree is still at the top, the lower branches will grow more slowly, and it is difficult to grow thick, and the seedlings will be delayed for several years before forming. Generally, it is better to start pruning after the second year depending on the growth potential.
