Powdery Mildew

The powdery mildew has made its annual visit to the garden. It seems worse this year than it has ever been. A part to the sprayer was lost when spraying started Sunday. Today the spraying needs to be finished up. There are two good organic remedies for powdery mildew.

A sulfur spray works well and fast. Just put about 3 oz of powdered wettable sulfur in a gallon of water and go to it. A little dish soap helps it stay in solution and stick to the leaves. The good thing about the sulfur is that it does not seem to damage the leaves. It also stays visible on the plant until the next rain. The sulfur will increase the acidity of the soil.

A baking soda spray works equally well. About 4 tablespoons of baking soda in a gallon of water with a little dish soap does the trick. The baking soda spray does seem to kill the leaves on which it is sprayed. It increases the alkalinity of the soil. Because it is invisible in the solution, it is difficult to tell if it is still there. For this reason we normally use the sulfur. We add cayenne to the solution to deter the deer and rabbits at the same time.
