1、 When

Most of these plants are sown with seeds in April in spring. At this time, the temperature is about 10-15 ℃, the soil has become soft from the hard state in winter, and the weather conditions are also suitable for sowing. Therefore, sowing at this time is conducive to seed germination. In the south, it is mostly sown in November. It has a strong ability to resist the cold. At this time, sowing can also send out buds

2、 Breeding method

1. Soak the healthy seeds in water for 48 hours. When water enters the seed and the seed becomes fat, pull it out of the water. Some fine-grained sand is mixed into the rotten leaf soil with abundant nutrients to make the soil with drainage performance and ventilation capacity. Bury the seeds in the soil prepared in the previous operation, and then pour some water slightly to make the soil have a certain amount of water. After about two months, the seeds will open a small mouth, which is suitable for sowing at this time

2. Sowing method: select a flowerpot with small holes at the bottom, and then put some loose and nutritious garden soil in the flowerpot. Put several small pits about two knuckles deep in the upper layer of the soil, and bury the seeds with openings. After the operation, put the flowerpot in a place with a little sunshine and take care of it carefully. It can grow small buds in a short time
