Due to the high temperature in summer and the large amount of transpiration of plants, sufficient water should be given. Water should be irrigated once in the morning and evening. In the morning and afternoon, water should be sprayed on the leaves and pots of the plants to enhance the humidity of the air. However, it should be noted that on cloudy and rainy days, watering or watering should be less, and rainy days should also be taken to avoid rain and prevent water in the basin.

5. Anti-disease Jasmine will be harmed by scale insects, red spiders and aphids in the summer. If it occurs, the number can be artificially captured when the number is small. When the quantity is large, the shell can be sprayed with 40% omethoate emulsifiable concentrate 1000 times. Insects and aphids, sprayed with 20% chlorfluazol emulsifiable concentrate 1000 times. Jasmine is vulnerable to leaf spot disease in summer, and it can be sprayed with 75% chlorothalonil 800 times when it occurs.
