1、 Ramet

From the end of August to the beginning of September, it is carried out in combination with basin change. Select the plant in good growth condition, take it out of the basin, and then use a small knife to divide it into several parts from the bottom for transplanting respectively. Pay attention to the later maintenance and do not touch too strong sunlight

2、 Cutting

1. Branches: in May, June, August and September, cut 4-6cm branches, preferably with 5-7 leaves on them. Dispose of the leaves at the bottom to prevent excessive consumption and evaporation of water. Dry them in the shade until the incision heals. The cutting medium uses clean river sand or pure vermiculite, which is easier to take root. It takes about half a month to take root and grow new leaves

2. Blade: select the robust blade, cut it from the petiole, wait until the incision becomes slightly dry, insert it obliquely or horizontally on the medium, and maintain the humidity. After about 10-15 days, fine roots can be sent out from the base of the leaves, and seedlings will grow after waiting for a period of time

3、 Tissue culture

This method is not common. It mainly uses the stem, leaves, flowers and flower buds of the plant as explants, and then adds various chemicals to induce the growth of adventitious buds. When the room temperature is adjusted to 25-27 ℃ and the light is exposed for 16 hours, small plants can grow in 4-6 weeks
