Fertilize once before sprouting and before flowering. After entering winter, it is necessary to reduce water supply, control plant growth and improve cold resistance. The potted plants are changed every 2 years.
5. Disease and pest control:
Leaf spot disease and tumor disease often occur. Spray with 600 times of 70% mancozeb wettable powder. Insect pests are harmful to shell insects and aphids, which are sprayed with 2000 times of 25% buprofezin EC.
