What causes white spots on lily leaves?

1. Reasons

Under normal care, the leaves of lilies are green. When white spots appear, it may be that the leaves have burned. Initially, the young leaves will curl inward, and then yellow-green to white spots will appear on the leaves. In severe cases, the white spots may darken, turn into brown spots, and eventually cause the leaves to curl. If left untreated, the disease will spread rapidly, causing partial shedding of leaves and young shoots, and the growth of the entire plant will be affected, causing it to stop growing.

II. Prevention and Control Measures

1. Prevention: Before planting, you must pay attention to prevention and try to choose varieties with strong disease resistance so that they are not easily infected. Check carefully for diseases and pests. The root system must also be kept intact without any signs of rot or blackening.

2. Planting: The planting depth should be appropriate, with a soil layer of about 6-10cm on the bulb. Planting too deep or too shallow is not conducive to growth. After planting, remember to spray water, especially in summer, when you should spray water several times a day. Also pay attention to shade to prevent excessive evaporation of water.

3. After the disease occurs: When the disease occurs accidentally, the diseased leaves need to be removed in time and then destroyed in a centralized manner to control the disease.
