Three highlights of elm bonsai: tender leaves, holes and tree bumps. Today, I will talk to you about the formation of elm acne by artificial means. So far, no authoritative organization has cracked the secret of how the elm pimple is formed, which is recognized as a means of self-protection of elm itself. Due to some stimulation, the internal tissue of elm stagnated and slowly expanded into a knot. And this kind of stimulation can be achieved by artificial means.
In early spring, when the elm just sprouted, the flat part of the trunk or the depression of the thin waist was hammered with a hammer, so that the internal tissue was depressed and the bark proliferated. In the healing period of about half a year or more, there will be raised bumps. Why early spring? At this time, the elm has accumulated nutrients for a winter. After the injury, rich nutrition can speed up the healing, which also makes the pimples in my heart form quickly. If you choose to grow acne in summer, the high temperature may make the wound rot, unable to heal and become sunken. In addition, the strength of the hammer tree should also be mastered. If it is light, it will have no effect; if it is heavy, it will be broken.
In the last picture, the three bumps in the picture are the positions of the three branches. The right side was trimmed earlier, and acne has already formed. The other two places have not been trimmed for a long time, and the wounds are relatively large. Now it is basically in the shape of a horse's eye, and it is estimated that it will take several years to heal naturally to form a pimple. When pruning branches, you want to form a knot in your mind. When trimming, don't trim it too concave, but trim it higher and more convex. Over time, the wound will become a knot in one's heart when it heals.
Where the ideal knot is formed, if the branch is too small and the knot formed after pruning is too small, don't rush to prune it. Before pruning, shake the branch first, hold the root of the branch with one hand and the upper part of the branch with the other hand, and shake it back and forth, left and right, so that the bottom part of the branch is shaken into a "sponge". In the growth period, the lower part of the branch will quickly thicken and bulge, thus achieving the purpose of forming a big node.
Elm has strong vitality and vigorous growth. In many cases, new branches will grow in or around the trimmed place. When the branches grow to a certain extent, a group of protrusions will be formed in the same way, and there are protrusions on the protrusions, which are very beautiful. Of course, there are also ways to make elms form a knot. For example, find some irregular gravel blocks and tie up the knotted parts of the elm trunk to simulate the state in nature. You can also make elm trunks form pimples, but you have to be patient. A pimple won't grow well in a few years.
