Triangle plum, also known as triangle flower, leaf flower. Its bracts are leaflike, purple or magenta. Although the flower friends all know that they need pruning after pruning, they still can't pay attention to the pruning. So how to prune after the bougainvillea? Pro, read along with Xiaobian~
Pruning after pruning Bougainvillea is very simple. First of all, we can't be dogmatic. We should know that Bougainvillea is very resistant to pruning, and the flowers of Bougainvillea are only bred on the top of new branches.
In short, you can cut back after the bougainvillea, and just cut off the short branches (you don't need to cut more, just cut off a little on the top). Long branch cutting 1 / 3 or 2 / 3 can be done. You can trim it according to your own modeling plan. You can cut it after each opening.
The purpose of pruning is to keep nutrients, many branches and compact tree shape, so we can also spare branches after flowering, cut off dead branches, weak branches and bore branches, and at the same time cut all the lateral branches to promote more new branches and form more flower buds.
Pruning methods of red triangle plum: 1
Short cutting means cutting off a part of annual branches, weighing short cutting if cutting more (such as cutting 1 / 2 ~ 1 / 3), light short cutting (such as cutting 1 / 3 or less), and middle cutting is called medium short cutting. The first bud (often called scissor bud) under the scissor is the most stimulated, and the growth of new shoots is the strongest. The farther away from the cut, the less the stimulation. After short cutting, the sprouting ability and the forming ability of branch were improved, and the effect of middle and short cutting was the best. Short cutting can weaken the thickening of mother branch.
2. Thinning
Thinning is the removal of annual or perennial branches from the base. The results showed that thinning could weaken the growth potential of the upper part of the scissor, but could promote the sprouting, branching and growth of the lower part of the cut. When the weak branches were removed, the above effects were not obvious in the pruning position, but they still promoted the growth of the whole tree as a whole. Thinning can reduce the shoot density, improve the light in the crown and promote the growth.

3. Shrinkage shear
Shrinkage refers to the pruning of perennial branches. The characteristic of shrinkage shear is that it can promote the growth of shoot and the germination of latent bud at the back of cutting, but weaken the mother branch. Shrinkage cutting is often used for rejuvenation of old trees. The application of shrinkage shear should also follow the principle of gradual and orderly. If the volume of the branch to be reduced is large, it should be cut in several times.
