1、 How to breed

1. Cutting method: it can be propagated by cutting method in spring. The time is from May to June. Cut the top bud or side branches without diseases and pests. The length is controlled at 5-8 cm. Remove the leaves at the base and leave one or two at the top. After treatment, put it in a cool place to dry the wound before cutting. After planting, it should be watered in time and placed in a ventilated and cool place. It can take root in about a month

2. Sowing method: it can be sown in the greenhouse in January and February every year. Its seeds are very small. It is recommended to mix well with fine soil before sowing. Directly on the soil surface without covering the soil. Finally, keep the basin soil moist, spray water frequently and put it in a cool place. Generally, it can germinate in half a month

3. Tuber method: it is usually carried out before germination. Use the sterilized blade to cut from the top of the tuber. Note that each tuber should have one or two bud eyes, and the wound should be coated with plant ash. It can be planted when the wound is dry in the shade. Be careful not to go too deep into the soil to avoid decay

2、 How to top

When the seedlings grow to 15 cm high, they can be toppled. Just cut off the branches at the top of the plant, which can promote the germination of more lateral branches and more flowers in the later stage. In addition, if any diseased branches are found during maintenance, the yellow leaves should also be cut off in time to avoid infecting other branches
