Cutting time is selected in spring or summer, about may to June is more appropriate, the temperature is just right in this period of time, plus the surrounding air humidity is high, so cutting is easy to survive, other seasons are not impossible, but the survival rate is not easy at this time.
If you want to cut the branches, first of all, you should choose a plant that grows healthily for at least three years, so that the branches on the mother plant can improve the survival rate. Cut the branches from the top for 1-2 years, and they should be plump. They should look thick and strong, with a length of about 15-25 cm, and then cut them into several stem segments, each of which keeps the growth point on the top and leaves at the bottom.
For it, the substrate can't use ordinary soil, because the permeability is not high, it is easy to be rotted if it is inserted in. It can be mixed with vermiculite, river sand, or water moss, bark and so on. The first premise is the permeability, apply enough water to it, and ensure the water content.
Insert the cut stem into the plant, do not need to be too deep, as long as you can ensure that it does not pour, during the normal water spray on the plant, until the white air grows on the root, that is, on behalf of the stable growth of the plant, you can transplant.
