The pruning time of yellow leaves is not fixed, so it can be pruned as long as it is in the growth period, and it is not easy to recover after pruning, because plants stop growing during dormancy. In addition, pruning is mostly carried out on sunny days. If it is rainy weather and the air humidity is high, the wound will be easily infected after pruning, which will affect the health of plants.

Second, the pruning method

1, new shoot pruning: Buxus buxus grows faster. If you don't pay attention to pruning the new bud, it will easily grow in vain. Usually, after the new branches grow, the 1-2 nodes at the top should be cut off, which can control the length of the branches and concentrate the nutrient supply to make them more robust.

2. Pruning of old branches: The old branches of boxwood need to be pruned regularly, mainly dead branches and diseased branches, and at the same time, the fine branches should be cut off to avoid consuming nutrients. In addition, for places that are too dense, it is also necessary to properly trim and cut off cross branches and overlapping branches to increase internal ventilation and light transmission.

3. Shape pruning: In addition to pruning new branches and old branches, boxwood should also be trimmed. For the branches that affect the appearance, they should be cut off in time to improve the appreciation. In addition, you can climb it to make a better-looking bonsai.

Third, nursing after cutting.

After the boxwood is trimmed, it needs to be placed in a cool and ventilated place, sprayed with carbendazim appropriately, and waited for the wound to dry. After that, add a little fertilizer, so that the plants can resume growth more quickly.
