Picking: the new technology of tree bonsai grows to a certain length after spring. Before lignification of new branches, the growing points at the tips of tender shoots should be picked by hand to prevent excessive growth of branches, reduce the spacing between branches, maintain a certain posture of trees, promote axillary bud germination and increase the density of branches and leaves. Generally speaking, you should start pinching cypress in late May with your fingers. If you use scissors, the wound will rust and affect appreciation. You can pick it in late summer. Broad-leaved trees prone to sprouting, such as Acer, Begonia Muguo, Boxwood, etc. Generally, take 2-3 (opposite) leaves from the new shoots and remove the tender heads. After half a month, they will grow new buds again and can be picked again. After picking the heart, the branches and leaves can flourish and the trees can be full.
Leaf picking: The foliage tree is the most beautiful in the new Ye Gang exhibition. For deciduous trees such as elm, maple, ginkgo and pomegranate, all the old leaves that are not beautiful enough can be removed in summer, and new leaves that are pleasing to the eye will grow in about half a month. Before and after leaf picking, decomposed liquid fertilizer can be applied for 2 ~ 3 times to ensure good hair leaves.
Sparse flowers and fruits: The flowers and fruits of American ginseng, boxwood, cypress and other trees have no ornamental value, so they can be removed in time to avoid consuming nutrition. Flowers and fruits trees, such as flowers and fruits, need thinning to keep the tree growing. It can avoid consuming nutrition and promote germination and growth.
Pruning: usually done around the long summer. The principle of pruning is to beautify the tree shape, which is beneficial to the growth of trees. The growth habits of trees should be considered, and flowering and fruiting should not be affected. Generally speaking, dead branches, pests and diseases should be cut off and burned at any time to prevent the spread; Cut off the long branches, too. If the location is better, you can also cut them short to control the growth. Too dense branches should be thinned, so that the branches are properly dense, which is conducive to ventilation and light transmission; Cut off the excessively long branches properly; All cross branches, overlapping branches and other branches that affect the shape must be trimmed; Attention should be paid to inducing branches to make the tree complete. Attention should also be paid to pruning: don't cut it while it is hot, the scissors must be sharp, the cut should be smooth, and larger wounds can be protected by sealing wax.
