Organic Disease Control - Fungicide/ Powdery Mildew Spray

1-gallon water

3 Tablespoons baking soda

1 Tablespoon bleach

1 teaspoon liquid dish detergent

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 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.

Got Milk!?

Some people believe milk has germicidal properties and is effective against powdery mildew. Hard to believe? Even if this is not true, the liquid calcium in milk is healthy and essential for your plants. Just make sure not to put a large amount of milk onto your plants or into the soil Too much of a good thing is not so good.

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

Organic Insect Repellents - Other Natural Materials

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