Its reproduction can be done in two ways. One is the sowing method, which is usually carried out in spring. Before sowing, prepare soil with strong drainage, then sow the seeds, cover them with thin soil and water them moderately to moisten them. After this treatment, they will germinate in about 10 days. The other is the cutting method, which is carried out in spring and summer, and the tops of young stems are selected as cuttings. When inserting, be careful not to dig it too deep into the soil. Water it thoroughly after inserting and keep it in a ventilated place. It will take about half a month for roots to take root.

1. Propagation method

1. Seeding: Seeding is a commonly used propagation method. The method is simple and the survival rate is high. Mostly done in spring. Prepare soil with strong drainage properties. For ground planting, the soil should be plowed in advance to ensure looseness. After preparation, sprinkle the seeds evenly on top, cover with a thin layer of soil, and water and moisten. After controlling the temperature and moisturizing in the later stage, it will take about 10 days to germinate.

2. Cutting: Cutting is mostly done in early May Carry out between August and select the tops of young stems for cuttings. The soil must be water-permeable, loose, and fertile. After processing, use chopsticks or wooden sticks to poke a hole in the soil surface, and then insert the cuttings. Be careful not to go too deep, just 2 centimeters into the soil. After inserting, water thoroughly and place in a ventilated place. As long as the humidity can be ensured, it can usually survive in about 10-15 days.

2. Cultivation methods

It has strong adaptability and is easy to cultivate. A certain humidity should be ensured at ordinary times, and watering should be done when it is dry or wet during the growing season. It is drought tolerant, so it should be watered dry rather than wet. In the early stage of flowering, a small amount of phosphorus and potassium fertilizer should be applied, so that the flowering period will be extended, the flowers will be larger and the flowers will be more colorful. In addition, be sure to get plenty of sunlight and not leave it in the shade for a long time, otherwise it will affect flowering.

There are many varieties, some of which cannot produce seeds. Those that are not inoculated can be propagated by cuttings. The method is also very simple and can ensure the survival rate. However, you should pay attention to the time when cutting. It is best to do it in spring and summer. The climate in the other two seasons will affect the survival.
