Sowing and propagation

Sowing from April to may in spring, because the seeds are small, they are generally sown in indoor pots. After uniform sowing, cover the surface with a thin layer of soil. When the pot soil is dry, it should be watered by soaking in the pot. Do not water directly to avoid washing away the seeds. Control the temperature at 15-25 ℃ after sowing, and germinate about half a month after sowing. Let the seedlings gradually see light after emergence. Seedlings are only the size of soybeans and grow slowly. Management must be cautious. It takes 2-3 years for seedlings to blossom.

Basin soil can be prepared by mixing 4 parts of rotten leaf soil, 3 parts of calcareous materials (shell powder, eggshell powder, aged ash wall debris, etc.) and 3 parts of river sand. When the small plants grow up, they can be replaced with large pots, but the planting cannot be too deep, otherwise it is easy to cause plant rot.

division propagation

Every spring, new fleshy leaves grow from the gap in the middle of the raw stone flower, expanding and cracking the old leaves, and the old leaves also die with shrinkage. The new leaves grow rapidly, shrink and crack again in summer, and 2 ~ 3 young new plants grow from the gap, which can be planted separately.

cuttage propagation

Nutrient soil or river sand, muddy carbon soil and other materials shall be selected for the soil. It is difficult to obtain an ideal cutting matrix for family cutting due to limited conditions. It is recommended to use the prepared and detoxified cutting matrix, including medium coarse river sand, but wash it with clean water several times before use. Sea sand and river sand in saline alkali areas should not be used. They are not suitable for the growth of flowers and plants.

In the peak growth season of early spring or late autumn (the maximum temperature at noon is no more than 28 ℃ and the minimum temperature at night is no less than 15 ℃), cut off the leaves or stems (with 3-4 leaf nodes), insert them into the matrix after the wound is dried, and spray the cuttings and matrix slightly wet. As long as the matrix is not too dry or water stained, the roots and new buds can grow quickly. When the temperature is high from late spring to early autumn, the cuttings are very perishable, so it is best not to cut.
