 Organic Disease Control - Fungicide/ Powdery Mildew Spray:


1 Gallon

3 Tablespoons Baking Soda
1 Tablespoon Bleach
1 Teaspoon Dishwashing Liquid


  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.

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.

Tomato "Juice" Spray- Works well to control aphids and other insects.


  • 2 cups Tomato leaves and stems

  • 1 quart water


  1. Put 2 cups of tomato leaves and stems in a food processor.

  2. Add 2 cups water.

  3. Process on high for two minutes.

  4. Let stand overnight.

  5. Strain through cheesecloth.

  6. Add 2 more cups of water.

  7. Spray liberally on roses and other plants that aphids are attacking.

Got Milk!?

Some scientists believe milk has germicidal properties, and is effective against Powdery Mildew? Hard to believe?

May we suggest: Copper Sulfate for Powdery Mildew control. It is naturally occurring.


Marigolds and Nasturtiums are commonly grown as companion plants as they keep pests away. Try putting some of the leaves and stems in your blender. Let it soak for a day, drain, add water to dilute and apply liberally.

If you are in to experimenting, look up other companion plants and give them a try. You just might invent a new recipe to share with us!
