Can pumpkin seeds grow in winter?
Even though the standard advice says to plant seeds in late spring to avoid frost damage, anecdotal evidence suggests that pumpkin seeds can survive winter and still come up in spring.
How do you store pumpkin seeds for the winter?

Can pumpkins survive a freeze?
Pumpkins can remain in the garden through a light, vine-killing frost. A light frost will not damage the pumpkins themselves. However, all mature pumpkins should be harvested before temperatures drop into the mid to low 20’s. Green, immature pumpkins will not turn orange after a killing frost.
Can I freeze pumpkin seeds to plant next year?

What month do you plant pumpkin seeds?
Sow traditional field pumpkins or jack o’lanterns into garden soil from May 15 to June 15.

What temperature is too cold for pumpkin plants?

How do you store pumpkin seeds long term?

How do you know if pumpkin seeds are viable?
One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.
Can I plant pumpkin seeds straight from the pumpkin?

What temperature can pumpkin seedlings tolerate?
Pumpkin Plant Temperature Tolerance
Keep them at 60 to 105 degrees Fahrenheit to germinate and harden them off before transplant. Planting too early can result in cold exposure that injures or rots the seedlings. The best time to transplant is when the soil reaches at least 65 degrees.

Do you have to dry pumpkin seeds before planting?
