In spring, the seeds are sown from April to May. Because the seeds are small, they are usually sown in indoor pots. After the seeds are evenly sown, a thin layer of soil is covered on the surface. When the basin soil is dry, it should be watered by soaking basin method. Do not water directly to avoid losing seeds. After sowing, control the temperature at 15-25 ℃, and germinate about half a month after sowing. Let the seedlings gradually see light after emergence. The seedlings are only the size of soybeans and grow slowly, so the management must be careful. It takes 2-3 years for the seedlings to bloom.
The pot soil can be prepared by mixing 4 parts of rotten leaf soil, 3 parts of calcareous materials (shell powder, eggshell powder, old ash wall chips, etc.) and 3 parts of river sand. When the small plants grow up, they can be replaced with large basins, but the planting should not be too deep, otherwise it is easy to cause the plant smear to rot.
Each spring, fresh fleshy leaves grow out of the gaps in the middle of raw stone flowers, which expand and crack the old leaves, and the old leaves die with shrinkage. The new leaves grow rapidly, shrink and crack again in summer, and 2-3 young new plants grow out of the gap, which can be divided into young plants.
Nutrient soil or river sand, mud carbon soil and other materials are selected as soil. It is difficult to get the ideal cuttage media for family cuttage due to limited conditions. It is recommended to use the cuttage media that has been prepared and has been detoxified. It is also OK to use medium coarse river sand, but it should be rinsed with water several times before use. Don't use sea sand and river sand in saline and alkaline areas. They are not suitable for the growth of flowers and plants.
In the early spring or late autumn (the highest temperature at noon is not more than 28 ℃, and the lowest temperature at night is not less than 15 ℃), cut the leaves or stems (with 3-4 leaf nodes). After the wounds are dried, insert them into the substrate, spray the cuttings and the substrate slightly. As long as the substrate is not too dry or water stained, the roots and new buds can grow quickly. From late spring to early autumn, when the temperature is high, the cuttings are easy to rot, so it is better not to cut.
