This Zucchini has been hit hard by powdery mildew. It doesn't visibly affect the fruit but I don't want it to spread and, since we have more than enough squash right now, I decided to try a radical intervention.
Here is the back of it where I have been trimming old or infected or dead leaves.
Here it is after all of the larger leaves have been removed. I left only 3 squash, 2 flowers and a newly emerging leaf. We'll see if it survives. I think soapy water is a treatment for powdery mildew but I'm going to look it up and treat what's left with an organic solution.

We've used a solution of baking soda, water, and a bit of Doc Bronner's with some degree of success .. .
ReplyDeleteThanks Chris, I'll give that a try.
ReplyDeleteI successfully used Pharm Solutions powdery mildew killer. It's orange, oily, and smells nice, as well as organic and safe to use on edible plants. I got it at Whole Foods but I've also seen it at the now failing Smith & Hawken.
