Is it possible for cucumbers and watermelon to cross pollinate? I have some of the largest cucumbers I've ever seen this last year. The plants were in close quarters of watermelons in a square box - 14'by 14.' Any ideas?

Not likely. They are not the same species. Here is more information: https://www.gardeningknowhow.com/edible/vegetables/vgen/cross-pollination.htm
