This is the Year of No Squash for us. The zucchini and yellow squash plants have been struggling all along, even though we rigged a shade-cloth canopy over them this year. We’re in southern Arizona, and temps have been consistently over 100 for at least a month, currently running around 108 the last few days. When a squash does get started, it wilts when it’s still tiny.
It just seems wrong to buy zucchini in the store during summer.
