1、 Breeding environment

1. Soil: it likes fertile sandy soil with good drainage performance, and it should be alkaline. It's best to test it with pH paper, between 6.5-7.5. It can be mixed with plant ash, fine sand, loess and rotten leaf soil. Add a small amount of fertilizer at the bottom of the basin as the base fertilizer to make the nutrients sufficient

2. Temperature: it is best to provide a cool environment during curing. The temperature is between 15 ℃ and 20 ℃. If it exceeds 25 ℃ for a long time, the leaves will curl and affect the flowering and growth. In addition, its cold resistance is also low. It can't be lower than 5 degrees in winter, otherwise it will stop growing

3. Watering: during the vigorous growth period, water once every three days, and the soil is moist. Also pay attention to spray more water and improve the humidity, so that the flowers will be more bright in the later stage

2、 Common diseases and insect pests

During the maintenance period, it is easy to be eroded by diseases and pests, such as red spider, poisonous moth, aphid, Verticillium Wilt and powdery mildew. When it is found, the corresponding drugs must be sprayed in time for prevention and control, otherwise it will seriously affect the plant growth. In addition, in the later stage of management, frequent ventilation should be provided to provide it with a cool environment
