Powdery mildew thrives and grows in really warm and dry climates, here in Colorado that is something we often have to deal with, it’s warm, it’s dry, no getting around that. The other condition it thrives in is when plants are too crowded, if there is not enough air circulation that can get around your plants, powdery mildew can get in there and take over.

I find the majority of my powdery mildew breakouts in my squash plants, which makes sense, squash plants grow huge leaves, they spread out and take up a large area. It’s easy for squash plants to get too dense and inhibit air-circulation, which is when powdery mildew comes to town.

What do you do about powdery mildew?

Early detection is important. Powdery mildew starts in the bottom leaves nearest the soil, so always get in there and look through your leaves in an attempt to identify problem areas. Once you identify the fungal diseases presence, snip off those infected leaves, don’t throw them in your compost, get them in the trash and get rid of the fungal spores.

Next, you want to take a solution that is one part milk, trust me it’s true, one part milk, ten parts water. Put that in a spray bottle and spray it all over the remaining leaves once a week. This will prevent the spread of your powdery mildew.

Trust me, I’ve been doing this for years, you don’t need chemicals, use the milk solution and you’l eradicate your powdery mildew problems.
