Argh, 2 weeks earlier than last year's start of PM season!
The last week has been hot and humid with some thunderstorms and a few showers. Maybe this weather contributed. But yes, alas this evening noticed it on several of the squashes, primarily the two vertical zucchinis but also most of the other squashes including the central patch just starting.
So, applied this mixture using my sprayer (recipe from this page: https://www.theartofdoingstuff.com/dealing-powdery-mildew/)
- 4 cups water
- 1/2 Tbsp regular vinegar
Will try this mixture for a few days. If it doesn't seem to be doing much, then I will go back to the baking soda mixture I started trying toward the end of last season -- BUT MUST BE VERY CAREFUL TO DILUTE IT PROPERLY.
Pruned a bunch of lower leaves from the two vertical zucchinis, and several leaves from the air conditioner ronde and both kitchen window zucchinis.
Completely pulled i.e. removed the west ronde de nice. It was still just a gaggle of leaves, nothing productive on the way at all, so why have all those PM-spreading leaves for no reason.
