I really should NOT even ask this question but just can't help myself!
How big do these mini pumpkin plants get?
I will confess my delicata winter squash DID grow in my pots although the BIGGEST one is probably still less than 6" long! But I keep finding new things to attempt in pots.
I was able to keep from trying to find any corn to grow in pots, and stuck with peas instead of trying for pole beans, but have had luck with summer squash and cucumbers, so maybe these mini pumpkins would work.
