Growing Info
Harvesting: Harvest pumpkins before the first fall frost, and when foliage has begun to dry out. Cut stem with a knife, leaving 3"–4" of stem on the pumpkin. Do not hold the pumpkin by the stem; if stem attachment gets broken, or any part of the pumpkin bruises, the pumpkin may rot. Brush off any dirt or leaves. Ideally, cure at 80°-85°F and 80–85% humidity or a warm, sunny spot with good air circulation for 1 to 2 weeks before eating or storage. Do not allow harvested fruit to get wet.

I’ve always had excellent experiences, four seeds look great and I am excited to see germinate. Unfortunately one seed will not be able to use.
Which best describes you as a gardener? IntermediateEGEpic GardeningFeb 16, 2026Hey Cage,
Thank you so much for this 4-star review and for sharing your experience with the Atlantic Giant Pumpkin Seeds! You're enthusiasm for growing giant pumpkins is exactly what we love to see!
We're sorry to hear that one seed wasn't usable. Even with our best quality control efforts, occasionally a seed doesn't make it through the process in perfect condition. The good news is that four healthy Atlantic Giant seeds should give you some amazing pumpkin growing potential this season!
Your excitement about germination tells us you're probably already planning for what could be some seriously impressive pumpkins. These Atlantic Giants have such incredible growing potential when they get off to a good start with quality seeds.
We hope those four seeds give you an absolutely fantastic growing season and maybe even a record-breaking pumpkin or two!
Keep on growing 🌻️

We haven't reached the end of the growing season in August in zone 7, but we've got a volleyball sized pumpkin on one vine and baseball sized pumpkin on the other. Big, healthy, vines have been disease and mildew resistant and have stood up to a hot, dry Spring and a hot, damp, summer. Can't wait to see how big we can grow a pumpkin!
