The pruning time of yellow leaves is not fixed. As long as it grows, it can be trimmed. In the dormant period, because the plants stop growing, it is not easy to recover after pruning. In addition, pruning is mostly carried out on sunny days. If it rains and the air humidity is high, the cut after pruning is easy to be infected, which will affect the health of plants.

Second, the pruning method

1. Prune new branches: Boxwood grows faster. If you don't pay attention to pruning the new bud, it will easily grow in vain. Usually, after the new shoots grow, the 1-2 nodes should be cut off at the top, which can control the length of branches, concentrate nutrient supply and 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, appropriate thinning should be carried out to cut off cross branches and overlapping branches. To increase the ventilation and light transmission inside. 3. Plastic pruning: In addition to pruning new branches and old branches, boxwood also needs pruning. For the branches that affect the appearance, they should be cut off in time to improve the appreciation. In addition, you can climb up and make a beautiful bonsai.

Third, nursing after cutting.

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