It is better to divide the plant from September to October. Dig out the whole root, shake it gently, remove the sticky soil, and then break it apart. It can be divided into several pieces, but each piece must have a root neck, at the same time, there should be one to two new buds, three to four small heel pieces.
In order to prevent the wound from rotting, it should be disinfected before planting. Before planting, it should be put in the wet river sand for germination, about 20 days, new roots can be born, but during this period, it must keep the sand moist, and can not be placed in the sun. Do not bury too deep when transplanting, or it will affect the germination and growth of leaves, but too shallow is not conducive to the absorption of water and nutrients.
If you choose seeds from the plants you plant, it's better to store them in June every year. At this time, the seeds will be fully mature. After the seeds are removed, they will be stored in a cool and dry place. They can be sown in autumn
Before sowing, let the seeds germinate. First soak the seeds in the water for a day and a night, then take them out and put them in the incubator. The best temperature for germination is between 10 ℃ and 15 ℃, and small sprouts can be produced in about 20 days. Too high or too low temperature will affect germination time, and even hinder seed germination.
When the buds grow 3 to 4 leaves, they can be transplanted and planted, about December to January.
In order to cultivate better plants, people often use seed propagation, and the method is relatively simple, later plant growth and flowering will be more robust and gorgeous.
