Atlantic Giant Heirloom Pumpkin Seeds

History

Atlantic Giant Pumpkin is the legendary variety behind every world-record-breaking pumpkin you've ever seen at a county fair or weigh-off competition — the variety that redefined what a pumpkin could be. Developed by Howard Dill of Windsor, Nova Scotia in the 1970s and 1980s through careful selection of the largest Mammoth pumpkins, Atlantic Giant was introduced commercially in 1981 and quickly became the gold standard for competitive giant pumpkin growing worldwide. Howard Dill's careful breeding work produced a variety capable of growing pumpkins well over 1,000 pounds under optimal conditions — with world records now exceeding 2,700 pounds. But Atlantic Giant isn't just for competitors — home gardeners across the country grow it for the sheer joy of watching something extraordinary emerge from a single seed. Open-pollinated and non-GMO, Atlantic Giant is a true heirloom that rewards patience, space, and a little gardening ambition.

Plant Profile

• Days to Maturity: 120–130 days from direct sow or transplant
• Fruit Size: 100–300+ pounds under typical home garden conditions; world-record specimens exceed 2,700 lbs
• Skin Color: Pale orange to pinkish-orange, deeply ribbed and heavily textured
• Vine Length: 20–25 feet — requires significant garden space
• Plant Type: Open-pollinated, non-GMO heirloom cucurbit

Flavor Profile

Atlantic Giant produces large quantities of pale, mildly sweet flesh that is best used for cooking, roasting, and processing rather than fresh eating. The flesh is dense, fibrous, and lightly sweet — excellent for pumpkin puree, soups, and baked goods when harvested at a younger, smaller size. Gardeners who harvest Atlantic Giant at 50–100 pounds find the flesh more tender and flavorful than fully mature specimens. The seeds are large, plump, and excellent for roasting — a bonus harvest from every giant pumpkin grown.

Growth Type & Harvest Yields

Atlantic Giant is a vigorous, sprawling vine that requires significant garden space — plan for at least a 20×20-foot growing area per plant for best results. Under typical home garden conditions with good soil, consistent watering, and full sun, plants will produce one to two pumpkins per vine averaging 100–300 pounds. Competitive growers who apply intensive soil preparation, controlled pollination, and aggressive feeding routinely achieve 500–1,000+ pound specimens. The variety performs best in rich, deeply amended soil with excellent drainage and consistent moisture throughout the long growing season.

Disease Resistance

• Good vigor and tolerance to typical garden conditions when grown in well-drained, fertile soil
• Susceptible to powdery mildew in humid conditions — ensure good air circulation around vines
• Protect young plants from squash vine borers with row cover until vines begin to sprawl
• Tip: Bury vine nodes along the length of the vine to encourage secondary root development and improve plant resilience

Growing Tips & Planting Dimensions

• Spacing: Plant one seed or transplant per hill, with hills spaced 20–25 feet apart — Atlantic Giant needs room to run
• Sow depth: 1 inch deep in warm, well-drained soil
• Germination: 7–10 days at soil temps of 65–85°F — do not sow in cold soil
• Full sun — at least 8 hours of direct sunlight daily for maximum fruit development
• Requires deeply amended, rich, well-drained soil — work in generous amounts of compost before planting
• Water deeply and consistently — giant pumpkins are heavy feeders and drinkers throughout the season
• For the largest fruit, hand-pollinate and select one pumpkin per vine to concentrate the plant's energy

When to Plant

Direct sow outdoors after all frost danger has passed and soil temperature is consistently above 65°F. In short-season climates, start indoors 2–4 weeks before last frost in biodegradable pots — pumpkins are sensitive to root disturbance. Atlantic Giant needs a long growing season of 120–130 days, so timing is critical — start as early as your climate allows. Find your frost dates and hardiness zone at the USDA Plant Hardiness Zone Map.

Companion Plants & Mutual Benefits

• Corn & Beans — the classic Three Sisters; beans fix nitrogen for the heavy-feeding pumpkin vine
• Nasturtiums — deter squash bugs and aphids when planted at the base of the vine
• Marigolds — repel nematodes and a variety of garden pests when planted around the perimeter
• Dill & Oregano — attract beneficial predatory insects that control aphids and squash bugs
• Avoid planting near: other cucurbits — pumpkins, squash, and cucumbers compete for space and can cross-pollinate

How to Enjoy

• Pumpkin Puree: Roast smaller Atlantic Giant sections and blend for a rich, dense puree perfect for pies, soups, and baked goods
• Roasted Seeds: Scoop, rinse, season, and roast the large seeds for a satisfying snack — Atlantic Giant produces an abundance of plump seeds
• Soups & Stews: Cube and simmer the flesh in hearty fall soups and stews for a mild, sweet pumpkin flavor
• Display & Decoration: Grow a showstopper for fall displays, harvest festivals, and neighborhood bragging rights
• Competition: Enter your best specimen in a local or regional giant pumpkin weigh-off — Atlantic Giant is the variety of champions

Harvest Tips

• Harvest when the skin has hardened and the stem begins to dry and cork — typically after the first light frost
• Use a sharp knife or pruners to cut the stem, leaving 3–4 inches of stem attached to the fruit
• Handle carefully — large specimens require multiple people and a sturdy sled or cart to move
• Cure in a warm, dry location for 10–14 days after harvest to harden the skin for storage
• Store in a cool, dry location — properly cured Atlantic Giant pumpkins can keep for several months
