Thank you, Diane! It says:
5b (-15 to -10 °F/-26.1 to -23.3 °C)
I have a good planter box with ten hours of direct sun and good pot soil.
Best, Billy
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!’ :)
