If you start a spray program early in the spring, which consists of one
tablespoon of the following:
black strap molasas
apple cider vinegar
spray weekly if you can on the foliage and provide good air circulation
for the plants. The above spray is to bump up the health of the plant
which will help it resist mildew and pest problems.
If you use 1-3 tbsp baking soda per gallon of water you will adjust the
pH of the leaf surface, which will make the plant virtually a hostile
environment to the powdery mildew.
