Powdery mildew loves areas of high humidity levels and warm, dry climates. It can be caused by various types of fungi, and manifests itself on the leaves with white patches. You can also spot powdery mildew on the undersides of leaves, on flower buds and immature fruit. The foliage will turn yellow over time and fall from the plant. It can be difficult to get rid of powdery mildew, so it’s best to completely avoid it in the first place.
How to Keep Your Plants Safe From White Powdery Mildew
- Water all plants at the soil rather than from overhead, which will cause the foliage to get wet. This will reduce the humidity level and keep other, moisture-loving diseases from infecting the plants and causing them stress.
- As it becomes later in the summer, stop using nitrogen fertilizer applications. New growth is more vulnerable to powdery mildew infection.
- Prune any overgrowth in the interior of shrubs to increase air circulation – this will in turn reduce the amount of humidity.
- If your plants are more susceptible to powdery mildew, grow them in higher elevations in your garden and try to avoid low, shady areas.
- Spray susceptible plants, such as some rose varieties and crape myrtle, with a preventive fungicide, such as Pure 3-Way.
