Powdery mildew is a fungus that will weaken and kill your plants. If left untreated it will infect the entire garden. The best way to prevent this powdery mildew is to understand the fungus and know what garden conditions will put a stop to the fungus from attacking your plants.

There are a few things that you can do to prevent powdery mildew. Know that you must check all of your plants for this fungus, even the ones you buy at garden centers.

1. Shop for and BUY healthy plants with green leaves and strong roots and stay away from the plants that are closeouts, not a good idea to nurse them back to health, they may be diseased and make your other plants in the garden sick.
2. Choose your gardens carefully, if your plants require full sun then give them what they need. All plants need airflow, so choose a garden bed that is not next to a wall or privacy fences.
3. Refrain from planting too close. Overcrowded gardens are attractive to powdery mildew due to the lack of airflow.
4. Keep gardens weeded. Watch for weed growth and pull out weeds when they are visible.
5. Remove all dead branches or leaves. Prune to keep plants healthy.
6. Water plants at the soil line with drip irrigation. Avoid getting leaves wet.
