1、 Sowing and propagation

1. Time: sowing method is a common breeding method, and the time is mostly in spring. The climate and temperature are very suitable in this season, which is conducive to its germination and growth. Of course, if the temperature can be well controlled, it can also be carried out in summer or autumn

2. Methods: the soil should be prepared before sowing. The soil should be loose and have good permeability. If it is planted in the ground, turn the soil deeply to ensure its softness. When ready, you can sprinkle the seeds on it. When spreading, try to ensure uniformity. Then cover it with a layer of thin soil, water it and wet it. New buds can be sent out in about 10 days. After the seedlings grow stably, they can be transplanted, and normal management is OK

2、 Cutting propagation

1. Time: this method is mostly used in varieties that will not bear seeds. If they cannot be sown and propagated, they can be carried out by cutting. It is recommended to choose the time between May and August every year. During this time, there is more rain and warm climate, which is conducive to germination and rooting

2. Methods: select the tender stem without disease and insect damage as cuttings, and control the length to about 5cm. The soil should also be loose, fertile and well permeable. When inserting, you should first poke a hole on the soil surface with a wooden stick, not too deep. The cuttings can penetrate into the soil for 2 cm. Put the cuttings in and carefully compact the soil. After that, it can be watered and maintained in a ventilated place. It will survive in about half a month
