What should I do if there are white things on the leaves of roses? What is the reason for the white hairs?

1. What is the white stuff on the leaves?

The white stuff on the leaves of roses is white spots, which is mostly caused by an unsuitable growing environment. For example, if the plants are kept in a humid environment for a long time, coupled with poor ventilation and stuffiness, such an environment will easily breed bacteria, which will infect the plants and cause diseases. In the later stage, leaf spot disease, powdery mildew, etc. will gradually form, and white powder and white spots will appear on the leaves.

2. How to treat

1. Timely pruning: If this phenomenon occurs, timely treatment is required. Cut off any leaves with white powder on them. If some branches have become dry, they should be cut off and the diseased leaves and dead branches should be cleared away to avoid infection.

2. Replanting: After pruning, the plant should be removed from the pot, the root system should also be pruned, rotten roots and blackened roots should be cut off, and the plant should be disinfected. Then prepare new potting soil, making sure it is loose and breathable. Then replant the treated plants in the soil.

3. Later maintenance: After planting, the plants should be placed in a well-ventilated environment, and the temperature and moisture should be controlled. Do not rush to expose them to direct sunlight. Wait until they resume growth before managing them normally. Pay attention to the maintenance environment in the later stage, ventilate more and get more sunlight to avoid reinfection of diseases.
