The method of dividing plants is the most suitable one in the family. It is easy and convenient to operate and has a high survival rate. It can be operated in spring or autumn. The plant is required to be more than two years old. First, take the plant out of the flowerpot, then remove the soil from the root and trim the part of the rhizome. Find a good position, cut the rhizome from the base of the clump, and ensure that there are more than 3 bud points on each clump. Make up the right pot soil, plant the divided plants separately, and then put them in the half shade.
The survival rate can be improved by pollinating seeds and then soaking them in water. Prepare suitable matrix, ventilate and drain well, and put it in the sun to dry in advance, so as to achieve the effect of disinfection. Choose to sow in the greenhouse, cover a layer of thin soil after sowing, often spray water to keep wet, also can cover with fresh-keeping film to keep warm and moisture, promote seed germination as soon as possible.
Tissue culture is suitable for large-scale reproduction, which is usually difficult to achieve in the family. It mainly uses the leaves, inflorescences, stem tips and stem segments of the plant, and uses the culture dish as the container to induce the bud growth with hormone hormone.
