The cutting time should be determined by the temperature. Cuttings were carried out when the temperature was higher than 25 ℃, because the high temperature was beneficial to rooting. The top of the stem with leaves or the lateral buds grown after being cut off can be cut and cut on the cutting bed with river sand as the medium. Maintain a high humidity, under the condition of 50%-80% light and 25-30 ℃, it can take about 30-40 days to take root and survive. The stems of the same year or perennials can also be cut into 5~lOcm segments and cut upright or recumbent on the cutting bed.

If there are conditions, dipping the cuttings with 1000 times the liquid speed of naphthylacetic acid or treating them with 0.01% APT rooting powder for one hour can promote rooting and survival. Indoor growers who saw the trunk into small pieces of 7~10cm and soak it in water are also easy to take root, but it is important to note that the trunk can not be reversed. At the same time, it is necessary to change the water frequently, keep the water quality clean, prevent the dry section from rotting, and add chemical fertilizer tablets to the water regularly to supplement nutrition.
