Here is one of my favorite recipes to combat powdery mildew:
1 Tablespoon of Murphy’s oil soap
1 Gallon of water
3 Tablespoons of baking soda
A spray bottle, or sprayer
Mix all ingredients together and pour into the spray bottle, or sprayer. Spray on affected plants.
I know it’s not quite that time of year yet, but it never hurts to be prepared. When you don’t have recipes like this handy it is too easy to go purchase the first chemical remedy you see at the supermarket.
Another place to get great organic remedies (again it’s one of my favorite places)is Gardens Alive!
