If it is a potted plant that has been planted for many years, especially after it is old, in order to prevent its flowers and branches from withering or getting old, it is necessary to turn over the soil every two to three years, and it is best to remove the old roots and branches in February and March every year. Its branches, buds and roots are particularly strong. The more branches are pruned, the more vigorous they grow.
Second, the new pile head pruning method
If it is a newly dug pile head, the planting season is from the end of each year to March of the following year. If the branches grow to 10 to 20 cm, those unnecessary branches can be removed, and the remaining branches need to be cut off appropriately, so that the water consumption can be reduced and the nutrients can be supplied to the piles in a centralized way.
Third, the method of pruning branches with injuries
If you cut the branches for various reasons, you can't sprout or cut the branches too early. It should be allowed to grow freely, which can help its wound to be closed and repaired in a natural state, and then its branches can be cut off.
Fourth, matters needing attention
1. Prune in time, preferably in late spring and early autumn. In these two seasons, its stump has the strongest germination ability, but the most vigorous growth. For its crazy branches, disorderly branches, or diseased branches, it is necessary to pull them out at any time. It should be noted that when the weather is hot, it is easy to burn its newly sprouted buds. 2. Prune once a year after autumn, remove some branches and leaves that are too dense, remove all kinds of messy branches and branches that are too lush, keep them in a certain posture, and help them become more dense. It has strong germination ability and needs to be plucked in time.
