Q.squashes
My mother-in-law says you shouldn’t plant various squashes close together because they will cross-breed. My neighbor has a huge garden and he plants all of his together. What is the real answer here? I am so confused! I don’t really know what I am doing lol. But I like to grow zucchini, summer squash, butternut, pattypan, pumpkin, acorn, cucumber, various melons just to give you an idea. So can I mix them together or with I end up with an alien gourd of some sort? Thanks for your help!!
