Re-treating powdery mildew

So after the baking soda treatment burned our squashes afflicted with powder mildew, we researched some alternatives. We decided to try a 20% mixture of milk and water.

There wasn't an immediate effect like with the baking soda, but some of the treated plants are looking better. We're going to have to retreat pretty frequently, but so far, it looks good.

Powdery Mildew

So our squash have been looking sickly for a while, and we've finally narrowed it down to Powdery Mildew. It's a nasty little fungus that grows on the surface of rough leaves as a result of humid conditions and poor air circulation. We looked up some remedies, and decided to try a mixture of baking soda and water (one tablespoon per liter)*.

We sprayed all of the infected leaves and then let them dry in the sun. It seemed to kill the mildew on contact. If this fails us, we've also read about a milk solution that can be applied to the leaves.

*We later learned that this mixture was too strong and burned some of our leaves.
