Big Max’ is the choice of giant pumpkin growers. Unlike some large pumpkins that are just blobs, ‘Big Max’ is round and has smooth, light-orange skin and is perfect for Halloween carving or other holiday decorations. To achieve maximum size, grow one pumpkin per vine, water and fertilize regularly. Excellent for canning (many cans!) or pumpkin pies (many pies!). Bright orange skin with 3″–4″ thick yellowish-orange flesh. Huge pumpkins can reach 20″ diameter and 100 pounds or more! ‘Big Max’ was introduced in 1964.

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.
