This year in the squash patch I experienced an outbreak of Powdery Mildew. A mold that appears commonly on the leaves of squash plants. Powdery Mildew can actually affect all kinds of plants including:

Squash & Gourds
Apples & Pears
Grapes
Onions
Cucumbers
Legumes
Melons
Wheat & Barley
Lilacs
Delphiniums
Zinnias
Daisy’s
Phlox

Likely a few more I have missed.

Good news is that you can manage it in a cheap eco friendly way. You do not need to run out and buy a bunch of fungicides.

This is a recipe that I tested this summer from a YouTube blogger “Project Diaries”.

His video came recommended from a lovely Twitter friend @JeanO_Appleseed, so I decided to give it a try and record the results. What attracted me to the recipe is that all the items required were already in my house and it did not contain any harsh chemicals.

Recipe:

1 Spray Bottle (Recycle a Windex bottle or buy one from the dollar store)
500 ml water (Just over 2 cups)
1-3 Tsp Baking Soda
2 Tsp Eco Friendly (Optional, I just used a few drops)
1 Tsp Vegetable Oil

Mix together and add to a spray bottle.

The results on this spray were excellent. By the next day I saw a mass reduction in Powdery Mildew.
