Giant Pumpkin
Atlantic Giant is the world-record holder among pumpkins, a competition variety that pushes the boundaries of what a single plant can produce. These massive F1 hybrids can reach 500 to 1,000 pounds under ideal conditions, though most gardeners will grow them to produce four to six medium-to-large fruits, each weighing well over 40 pounds. Maturing in 120 days from direct seeding, they thrive in full sun with moderate water and slightly acidic soil (pH 6.0-6.8). The flesh is stringy but genuinely delicious, rich in fiber and beta-carotene, making these giants far more than decorative jack-o-lantern fodder.

These pumpkins hold the world record for sheer size, yet each vine can produce multiple 40-pound fruits if you remove the competition. The seeds are plump and delicious when roasted, offering a bonus harvest beyond the flesh itself. Re-selected by seed companies for improved shape and uniformity, Atlantic Giant combines the thrill of competitive growing with practical utility in the kitchen and genuine flavor that rewards the space and time they demand.
Despite their massive size, Atlantic Giants serve multiple purposes in the kitchen and beyond. The flesh, though stringy, is genuinely delicious and well-suited to roasting, purees, and pumpkin-based soups where that texture becomes an asset rather than a liability. The seeds are plump and excellent for roasting as a snack. These pumpkins also serve decorative purposes through the fall season, their impressive size commanding attention on porches and at market displays. Some growers preserve them whole through careful curing and storage, keeping them firm and unblemished for months as functional fall décor.
Sow indoors 2 to 3 weeks before your average last frost date, planting 2 to 3 seeds per 2-inch container or plug flat. Germinate at 75-95°F, then thin with scissors to one plant per container. Harden plants for 4 to 7 days in cooler conditions before transplanting outdoors after frost danger has passed and weather is warm and settled. Use biodegradable pots if possible so they can be planted directly into the ground with minimal root disturbance.
Transplant after your average last frost date when weather is warm and settled, handling seedlings carefully to minimize root disturbance. Space plants according to row recommendations (3 inches apart with 4 to 10 inches between rows, depending on whether you're growing for maximum fruit size or quantity). Ensure soil temperature is at least 65°F at planting time.
Direct sow 2 to 4 weeks after your average last frost date when soil temperature reaches 65-90°F. Plant seeds 1 inch deep in hills or rows with adequate compost worked into the soil. Keep soil evenly moist but not waterlogged as germination occurs. Thin seedlings to one plant per mound when several leaves have emerged.
Harvest Atlantic Giant pumpkins when they reach full maturity and the skin feels rock-hard to the touch. The rind color should be a deep, uniform orange with no soft spots. Leave fruits on the vine as long as possible, but protect them from hard frost; light frosts can be tolerated, though an early freeze will damage the crop. Once fully mature, cut pumpkins from the vine with a sharp knife, leaving 3 to 4 inches of stem attached. Field cure harvested fruits for 1 to 2 weeks in dry, sunny weather to dry and toughen the skin for longer storage; if weather is rainy, move them indoors to a warm, well-ventilated space at 80°F to cure.

“Atlantic Giant emerged as a breakthrough in pumpkin breeding, selected and re-selected by commercial seed producers for consistency and record-breaking size potential. The variety represents deliberate hybrid vigor, crossing genetics to produce plants capable of channeling all their energy into single massive fruits or a handful of substantial ones. Its rise to fame is inseparable from the competitive pumpkin-growing movement, where enthusiasts worldwide use Atlantic Giant as their baseline for challenging weight records and pushing horticultural limits.”
