My son wants to grow watermelons in his little patch, so for the first time I'm ordering them. We probably don't have space - his patch is only about 3'x4' and he also wants to grow a tomato in there. I figure I'll try and direct the vines in a circle on the ground around the base of the tomato. Maybe it'll work? Any watermelon growing tips? I'm in the northeast, so not your prime melon growing territory.
