Fungicide/ Powdery Mildew Spray:

Ingredients:

  • 1Gallon Water
  • 3 Tablespoons Baking Soda
  • 1 Tablespoon Bleach
  • 1 Teaspoon Dishwashing Liquid
Extremely important:

Do not use too much bleach! Use no more than 1 part bleach to 10 parts water. We hesitate to recommend using bleach as it can harm your plants if too much is applied. Use it at your own risk and try to avoid spraying it on healthy leaves.

Instructions:

  1. Snip and remove leaves that are worst affected.
  2. Mix ingredients with water.
  3. Spray remaining leaves top and undersides.
  4. Apply a heavier dose on leaves that have signs of infection and only lightly
    on unaffected leaves as bleach can actually harm and discolor the leaves.
