Just stay away from anything that grows as a vine and not a plant. Things like pumpkins will overtake your garden, trust me I know. My surprise pumpkin patch many moons ago overtook half my mom's garden and threatened to destroy the whole thing until she hacked it back. You have to be very careful with things which grow like that. It was so much fun to grow my own pumpkins for Halloween. That's what I grew them for no joke, they weren't used for pie or anything else just jack-o-lanterns. LOL
