It can be propagated by cuttings, grafting and sowing.
Cutting can be done by cutting the fully grown metamorphic stems in spring, which are easy to take root. However, after cutting off the stem nodes, they must be placed in a cool place for 1 to 2 days, and then inserted into the sand bed after the incisions are slightly dry. , the humidity should not be too high after transplanting to prevent the incision from rotting. Roots will take place in 3 weeks.
To cultivate an umbrella-shaped hanging plant shape and increase the ornamental value, grafting is generally used. Compared with cuttings, grafting propagation has vigorous growth and early flowering. Grafting is best in spring and autumn. Because the temperature is suitable, the survival rate is high. When grafting in the high temperature and high humidity season in summer, the incision is prone to infection and rot, and the survival rate is low. Cactus plants can be used as rootstocks, but Hylocereus undatus (Hylocereus undatus) and Tiger thorn (Pereskia aculeata) are better. When grafting, choose strong, thick, tall Use a 30cm plant as a rootstock, cut off the top 10cm, leaving 20cm, and cut it into a wedge-shaped mouth. Then cut the full scion of the crab claw (3 to 5 nodes are appropriate), cut the lower end into a duckbill shape, and cut it into a wedge shape. Immediately insert it into the wedge-shaped crack, and the insertion depth should be as deep as the woody part of the rootstock center. In order to prevent the scion from slipping, pins or cactus thorns can be inserted and fixed. Some rootstocks can be connected to 2 to 3 scions. If you use a leaf cactus as a rootstock, cut a slit longitudinally on the top of the rootstock, insert the scion cut at the lower end, and tie it with thin strips of plastic film, or fix it with cactus thorns. After grafting, it should be placed in a cool place with high air humidity. After about 10 days, if the scion still remains firm and bright green, it has healed and survived and needs careful maintenance. After one month, a wire rack can be set up to make the scions evenly placed on the rack, and gradually placed in a sunny place for normal management.
