1. Sowing and propagation

First, collect seeds. This process is usually carried out from September to October, because the seeds are just mature at this time. Before sowing, soak the seeds in water, and the water temperature is about 50 ℃. Sowing should be carried out in the way of trenching and drilling. The soil should be fertile enough. It is best to use sandy loam. After sowing the seeds, lay a layer of soil about 2 cm later. After watering, lay a layer of fresh grass on it. Pay attention to keep the soil moist all the time. Seedlings can grow in about 2 months, and then they can be planted separately in the next spring

2. Grafting propagation

To choose this breeding method, seedlings that have grown for 2 to 3 years should be used as rootstocks. If you want budding, it's best to do it from July to August. If you want cutting, it's better to do it in autumn. After cutting, cover all the scions with soil, and remove the soil when the next spring is about to pass. If it is cut indoors, it should be stored in wet sand after it is connected. After the joint is healed, it can be transplanted before it germinates in the next spring

3. Cutting propagation

Select the branches to be cutted. It is best to select Jianzhuang branches from the plants that have grown for one year. The length of the branches is about 15 cm. Then it is best to keep two leaves on them, and about one third of the leaf surface of each leaf should be cut off. After the branches are inserted, pay attention to avoid being illuminated by strong light, and water them frequently

4. Ordinary batten

This method is best carried out from February to March. Cut the base of your selected branch in half, and then cut a section upward. Put a tile in the middle, and then press it slowly into the soil. Be careful not to break it, then fix it with iron wire, and finally pile the soil. After the root buds grow out of the pressure strip, you can cut it down and plant it in the soil

5. High branch pressing

Before entering the summer dog days, cut off the strong young branches with a diameter of 1.5 to 2 cm on the mother plant, cut a crack under the basin fork, cover the bamboo tube with soil inside, tie the outside tightly with a rope, and then spray water on it often, but pay attention not to spray too much. In this way, he can grow new roots around May of the next year. At this time, we can take it down and plant it
