What is potassium carbonate? Also known as potassium hydrogen carbonate or potassium acid carbonate, potassium carbonate (K2CO3) is a white, alkaline solid used in fire extinguishers, wine making, to make club soda, and to neutralize acids. As a base, potassium bicarbonate is at the high end of the pH scale. If you have alkaline soil, studies have shown that using potassium bicarbonate does not alter sodium levels in your soil, plants, or runoff water. If your garden plants commonly suffer from fungal diseases, potassium bicarbonate may be exactly what they need.
Powdery mildew is a widespread plant fungal disease that affects both edibles and ornamentals, but when you find that your squash vines or rose bushes appear to be covered in white dust, all hope is not lost. You can control or eliminate powdery mildew, and there are preventative measures you can take before it appears.
Powdery mildew thrives on dry foliage in high humidity and moderate temperatures, especially in low-light conditions, or when plants are crowded. But if you have powdery mildew in your vegetable garden or on your shrubs and trees, here's some good news for you: Powdery mildew is host-specific and will not jump from one type of plant in your garden or landscape to another.
Potassium carbonate: Potassium carbonate is a contact fungicide that kills mildew spores quickly, and it's also approved for organic growing. Oil is not necessary when using potassium bicarbonate for mildew control. Just mix half a teaspoon of liquid soap with a gallon of water, then stir in 1 tablespoon potassium bicarbonate and spray lightly on leaves.
