Here’s a guide for when to harvest pumpkins for each region of the United States. Pumpkins come in many different colors and sizes and are best not harvested until they reach their intended size. It is easy to tell when pumpkins are ready if you know how big and what color they are supposed to be. They’ll develop their full, solid color (which is orange for most pumpkins) and size when they are ripe. They’ll also feel hard to the touch and sound hollow if you give them a thump. While they are typically ready around Halloween, pumpkins can take anywhere from 75-120 days to mature and this can vary from region to region.

TIPS & ADVICE
Use shears or clippers to cut pumpkins off the vine. They are best with about 3 inches of stem left attached.
Pumpkins should be cured in the sun after harvest for about a week. This will allow them to develop a thick, outer layer. Store them in a cool, dark place to preserve their post-vine life.
Harvest times for pumpkins may vary by 2-3 weeks in any given year based on varying climate patterns.
Be sure to note the ‘days to maturity’ for your particular type of pumpkin when planning to harvest, because they can vary by more than a month.
