- Vegetables like cucumbers and squash
- Fruits such as grapes and apples
- Flowering plants including roses and zinnias

How Can I Prevent Powdery Mildew?
Prevention is always the best first step when learning how to treat powdery mildew. Here are several strategies to consider:
-
Choose Resistant Varieties:
Select plant varieties that are known to resist powdery mildew. Many seed catalogs indicate their resistance levels. -
Improve Air Circulation:
Space your plants appropriately to ensure good airflow. Avoid overcrowding, as this creates a humid environment that promotes fungal growth. -
Water Wisely:
Water your plants in the morning to allow any moisture on the leaves to evaporate throughout the day. This reduces the chances of fungal growth. -
Mulch Your Garden:
Using organic mulch can help suppress the growth of weeds and create an environment that deters fungal spores. -
Use Pruning Techniques:
Regularly prune your plants to remove dead or heavily infested foliage. This allows for more light and air to reach the inner parts of the plant.
By implementing these preventive measures, you can significantly reduce the risk of powdery mildew in your garden. However, if you do notice signs of powdery mildew, here are some organic treatment options to consider.
