cross-pollination of Squash
I am hoping to plant summer squash and zucchini in my garden this year. But I read recently that the recommended distance to avoid cross-pollination is 1/4 mi. Not sure where I found that information or how reputable the source was. Can anyone tell me if they've managed to avoid cross-pollination in a backyard garden? I can separate them in different raised beds that are about 30-35 yards apart, but that's the best I can do.
