1、 How high is the top

The growth rate of this kind of plant is relatively fast, and the plant will grow very high in a short time. But if the plant grows too high, it will lose its ornamental and make it no longer beautiful. Therefore, when the plant grows to 1.6-1.8m, it is necessary to top the plant and trim the branches slightly to make the plant return to a beautiful state

2、 Topping method

1. Pruning tender buds: top the plant every spring. At this time, the temperature and moisture content in the air are suitable for the growth of the plant, and the plant has just begun to grow leaves. At this time, first cut off the newly grown leaves on the head of the plant, and then cut the longer branches to make the plant reach its desired height. This can prevent the plant from growing at will and growing to an uncontrollable height. After pruning, do not let the wound of the plant touch water, so as to prevent the plant from being infected with bacteria

2. Fertilization: after topping the plant, apply some fertilizer to help the plant grow. Compound fertilizer can be added to the plant once a half month, but the concentration of fertilizer should not be too high, so that the growth speed of the plant will become faster. If the branches are thin, you can give the plant some fertilizer containing nitrogen and potassium so that the branches can become strong
