1、 Time selection

For the seedlings at the beginning of growth, when the plant grows to 10-15cm, 5 or 6 small leaves have grown on it. At this time, it is necessary to topple and pick the heart, which can effectively control the height of plant growth. For adult plants, it can be carried out in spring and autumn. At this time, the temperature is relatively mild and has little impact on the plants, which can promote the growth in the future

2、 Method steps

1. Prepare tools: before topping and coring, prepare suitable tools. You can use a sharp pair of scissors and disinfect them in advance

2. Determine the position: before starting, determine the pruning position and node. Start from the top to find the node. The top leaves on the main stem and side branches need to be removed. The pruning height is about 3-5cm. It should be noted that the topping length cannot be too long for seedlings

3. Pruning: after the position is determined, pruning can be carried out, and the part can be removed with scissors to keep the cut flat

4. After pruning, keep it in a cool place, not in the sun. After the incision is dried, it can be maintained normally. Pay attention to watering and fertilization
