The best sowing time of cactus is from May to June or from September to October. The best temperature is 20-30 ℃. Seeds should be soaked in water for 2-3 days and allowed to absorb water. Soak the bottom of the basin with water infiltration method. Then, the whole plant is sealed with plastic film, placed in a room temperature of about 25 ℃, and germinated in about a month.
Cutting is suitable for the peak season of cactus growth in early spring and late autumn, and April to May is the most suitable.
Either 1-4 stem nodes or large branches with branches can be taken for cutting. When cutting, the wound shall not be stained with water, and shall be dried in the sun for two or three days to make the wound heal and not perishable. Rooting after the pre shade, less water, about 20 days to root.
The best way of cactus grafting is to insert, which is not easy to dry and fall off. The insertion method is the "up" type connection method. The healthy and sterile seedlings were selected, and the cactus plants with good growth were selected as rootstocks.
After grafting, move to the place where the light is not strong. The temperature is controlled at 20-25 ℃, and the wound will heal in 15-20 days. Gradually move to a well lit place for maintenance. The culture soil should be loose and permeable, and the water quality should be neutral.
