1、 Breeding environment

1. Soil: it is best to use soil with good permeability and drainage

2. Ventilation: air circulation can prevent the occurrence of diseases. Watering should be thorough in order to bring fresh air into the soil

3. Temperature: the suitable temperature for its growth is 15-28 ℃. When the temperature is lower than 5 ℃ or higher than 35 ℃, it will enter the dormant state and stop growing

4. Fertilization: compound fertilizer can be used for fertilization. Thin fertilizer should be applied frequently, and the amount of fertilization should not be too much, otherwise it will cause fertilizer damage

2、 Breeding method

Cutting propagation: cut the healthy branches without flowering into 2-3 sections, coat the cut with plant ash and insert them into the soil. Put it in a semi shade environment without watering in a week, and new plants will grow in 1-2 months

3、 Common diseases

1. Anthrax: it mostly occurs on the leaves, and many spots will appear. After finding it, cut off the damaged leaves in time to avoid harming the health parts, and then spray it with carbendazim solution

2. Macular disease: after the onset of the disease, there will be yellow spots on the leaves, and black mold will appear in the spots. When the disease occurs, use chlorothalonil powder to control it
