• 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.
