How do you control tree growth in stump bonsai through pruning methods?
Using pruning methods to control tree growth in stump bonsai. Stump pruning can control tree growth, keep the tree dwarf, encourage branching and make the leaves dense, achieving the artistic effect of turning a large tree into a small one and embodying the large within the small. At the same time, pruning is also an important measure to ensure that stump bonsai plants grow and develop normally, bloom and bear fruit (referring to flower-and-fruit bonsai), and stay old but not declining under the conditions of little potting soil and limited water and fertilizer. Generally, deciduous tree species (such as elm, Japanese bush cherry, trident maple, etc.) can be pruned all year round, but the best time is after leaf drop and before bud break, because at this time there are no leaves on the tree, so the growth of the branches can be seen clearly and it is easy to work. For flowering bonsai plants, those that bloom on new branches of the current year (such as ornamental pomegranate) should preferably be pruned before bud break, while those that bloom on perennial branches (such as plum blossom) should preferably be pruned after flowering. Slow-growing evergreen trees should preferably be pruned in winter; for pine species, since they tend to bleed resin after pruning, they should preferably be pruned at noon on a sunny winter day.
