"Special" tree-shaped apple trees are typically the result of improper pruning, poor cultivation practices, and other unfavorable environmental factors. To transform these irregularly shaped trees into well-structured ones, proper pruning and management techniques must be applied.
1. Trees that have become overly dense due to neglect in their growth often suffer from overcrowded canopies, poor light penetration, and low fruit yields. Pruning such trees doesn't necessarily require removing the entire structure. Instead, it should be done based on the specific condition of each tree. The first step is to open up the branch angles, select promising branches to serve as main or secondary branches, and gradually remove or shorten other older branches each year to balance the tree's structure. In some cases, there may be too many main branches or lateral branches that are too far from the trunk, which needs careful adjustment. The main branches can help fill in spaces where side branches could be developed. Over time, non-essential branches should be pruned back to encourage the growth of multiple-axis branches. To avoid a significant drop in production, some single-axis fruiting branches should be left in place. Once the tree has produced a lot through multi-axis branches, the slender single-axis branches can be removed.
2. Trees with lopsided canopies often develop this way due to years of imbalanced pruning, mechanical damage, or external obstacles. This leads to an uneven crown shape, weak growth, and reduced productivity. To correct this, focus on the side of the tree that lacks main branches. Use techniques like retraining vegetative shoots, supporting, and pulling branches to encourage the development of new main branches and fill in empty areas. On the denser side of the tree, remove some branches to improve air circulation and light exposure. On the sparser side, prune selectively to stimulate growth. By doing so, the tree’s growth potential can be balanced more quickly, leading to a more uniform canopy.
3. Small but not very old trees that show weak growth need special attention. Pruning should be combined with improved soil management, increased fertilization, and adequate watering. It's also important to eliminate excessive flower buds, especially on the extension branches of dry stems for three consecutive years. Avoid allowing fruiting on these branches. In addition to thinning flower buds, short fruiting branch groups should be pruned back appropriately to allow for renewal. When making cuts, try to avoid damaging the main structural branches, particularly large wounds, as they can weaken the tree and hinder its healthy development.
