First, I need to know what your Hardiness Zone is, and then I can help!
Pumpkins need 100+ growing days, so it might be dicey up there! ;)
Plug your Zip Code in here and let me know what comes up:

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
