I’m in Zone 5a, so you’re a tad warmer than me. You should be able to do grow Pumpkins, but you’ll be limited by growing it in a planter box. You’ll need to look up special instructions for that.
I have absolutely NO experience in doing that. When it comes to Pumpkins and other Winter Squash, we have a large area where they’re free to roam.
Good Luck, though! If successful, you’ll have invented a ‘new thing!’ :)
Ha ha! Thank you, Diane! Yeah, the other unusual thing here is that my “back yard” is the Pike National Park, so I get lots of deer visitors who like to eat my plants. 🤪🐻
