RE: bee balm

Bee Balm, "Monarda", is susceptible to many fungal diseases when weather conditions are right for them to develop, usually warm and humid weather. Sprays of 1 teasspoon Baking Soda mixed in 1 quart of water have been effective for me in controlling the rare fungal disease such as Black Spot, Powdery Mildew, etc.
