Pruning of Bromus Bromus is exactly when it is in vigorous growth. If the tree is in bad growth, it is not easy to recover, and branches may be lost. However, for Bromus, a tree with unique physiological structure, it is not possible to prune it at will. We should not only grasp the pruning frequency, but also pay attention to the pruning time, including some pruning skills.

For the bonsai bromegrass, the purpose of pruning is mainly modeling. In terms of subdivision, it can be divided into minor shaping at ordinary times or big fighting during modeling. Although the purposes of these two pruning are the same, the actions are different. Therefore, we should be extra careful in the choice of time.

1. Pruning of plastic surgery

I call it pruning of plastic surgery to shape bonsai. Generally speaking, it is chosen in late winter and early spring, and it is safer before and after the "fright" of the lunar solar term according to the different temperatures and climates in different places. At this time, after a winter of nutrient accumulation, the bromeliads have strong germination and are conducive to recovery, which is a good time to make a big fight.

2. Maintenance pruning

This pruning is mainly to maintain the beauty of the shape. It is usually aimed at the bonsai that has been shaped, just like our ordinary haircut, not to change the hairstyle, but to trim it. For bromeliad bonsai, this work can be done twice a year, and it is not recommended to overdo it. You can choose one time between June and July and the other time between September and October every year. The basic principle is to avoid high temperature weather and catch up with the vigorous growth. Because, when the temperature is high, Bromus is dormant, which is not good for recovery, and the time of vigorous growth is just to reshape it.

3. Precautions for pruning

Here, we mainly talk about maintenance pruning. For Bromus, each branch and root has a symmetrical relationship, and each branch is also related to the corresponding root system. In the process of growth, the root system provides nutrients such as water and fertilizer to the branches and leaves, and the branches and leaves absorb light for photosynthesis and feed back the root system. Therefore, in the process of pruning bromegrass, we should be careful to avoid bumping the tree. For the repair of its crown, it is necessary to consider the overall coordination and balance, and each layer can be slightly repaired, that is, to meet the needs of modeling, but also to take into account the lighting and ventilation of the inner branches and leaves, and not to trim too much.
