Most pumpkin patches in the US open the last weekend of September and close on October 31. Warm states run a little later and can stay open into mid-November. Opening day has less to do with when pumpkins ripen and more to do with Halloween.
If you are planning a trip, aim for the first three weekends of October. That window works almost everywhere. Patches are fully stocked, the weather still cooperates in most regions, and you stay ahead of the picked-over final days before Halloween.
Opening day clusters around the last Saturday in September. Closing day is even more predictable. The vast majority shut down on October 31, because the product is tied to a single holiday.
Why the dates move year to year
Three things shift the calendar.
Planting time comes first. Pumpkins need roughly 90 to 120 days from seed to harvest. A wet spring that delays planting pushes ripe pumpkins later into the fall.
Weather during the season matters next. A hot, dry August can bring pumpkins in early. A cold snap can slow everything down.
First frost sets the back end in colder states. Once a hard frost hits, the vines are done and the field stops producing. Patches in the northern tier watch the forecast closely in October.
None of this changes the Halloween deadline. Even a farm with pumpkins left on November 1 usually closes, because demand falls off the day after Halloween.
Opening season by region
The regional spread is smaller than most people expect.
The Northeast and Upper Midwest open mid to late September. Think New England, New York, Michigan, Wisconsin, and Minnesota. Cooler nights get pumpkins coloring early.
The Mid-Atlantic, central Midwest, and Mountain West open in the last week of September. This is the biggest group, covering Pennsylvania, Ohio, Illinois, Colorado, and Missouri.
The Pacific Northwest opens late September and often runs the full length of October with cool, dry picking weather.
The South and Southwest open early October. Texas, Georgia, Florida, Arizona, and Southern California start later and can extend past Halloween, since there is no hard frost to end the season.
For exact local dates, see the state-by-state pumpkin patch season guide and always call the specific farm before you drive out. Individual patches vary by a week or two even within the same county.
When patches actually close
October 31 is the wall. Most patches treat Halloween as their last real day.
A smaller number run a short clearance stretch into the first week of November, selling remaining pumpkins at a discount. A few farms with corn mazes and other attractions stay open through Thanksgiving, but they are the exception, not the rule.
If you want the best selection, do not wait until the last week. The final days before Halloween are when fields get thin and the good pumpkins are gone.
Frequently asked questions
Do pumpkin patches restock during the season? Larger agritainment farms usually do. They truck in fresh pumpkins to keep the display full. Small pick-your-own fields typically do not, so their selection thins as October goes on.
Are any pumpkin patches open in November? In warm states, yes. Parts of Texas, Florida, Arizona, and California run into mid-November. In cold states, almost none stay open past early November.
What is the best weekend to go? The first or second weekend of October. Full stock, decent weather in most of the country, and no Halloween crowds yet.
