Thanks everyone. I do have pumpkins in this patch and the leaves of the mystery squash are more like the long green zucchini. I know I had seeds for round zucchini but must have trown out the package by mistake. These rows are about 150 feet long and the squash 2 rows spread to be about 24 feet wide combined. This garden is in remote NE Alberta and has very long days, almost 18 hour in Late June and into July. Rain water and no chemicals at all. We till in the mustard that grows throughout the garden as a green compost of sorts to add nutrition. I will post a photo of the summer squash in a few hours
