1. How high should the topping be?This type of plant grows relatively fast and can grow very tall in a short period of time. But if the plant grows too high, it will lose its ornamental value and make it no longer beautiful. Therefore, generally when the plant grows to 1.6-1.8m, it is necessary to top the plant slightly and prune the branches to return the plant to a beautiful state. 2. Topping method1. Cut young shoots: Top the plants every spring, when the temperature and moisture content in the air are suitable for plant growth, and the plants have just begun to grow leaves. At this time, first cut off the newly grown leaves on the top of the plant, and then cut the longer branches to make the plant reach the height you want. This will prevent the plant from growing randomly and reaching an uncontrollable height. After pruning, do not let the wounds of the plant come into contact with water to avoid the plant being infected by bacteria. 2. Fertilization: After topping the plant, apply some fertilizer to help the plant grow. You can add compound fertilizer to the plants once every half a month, but the concentration of the fertilizer should not be too high so that the growth rate of the plants 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 thicker. |
