kbumgar,
I am fortunate to live in the mountains. The highs here have only just this week started to hit the 90's. My squash are growing like topsy and they are blooming and fruiting. When I was planting, I dropped a seed in some really poor sandy soil, evidently, and there is a plant growing there. I even forget to water it most of the time. I'm growing Cavili, an early light yellow one, and tromboncino, a late light yellow one. Notice the strange pale mottling on the leaves. Any idea what causes this?
