C. maxima. Dill's Atlantic Giant pumpkin seeds hold the world record for giant pumpkins, and produce the largest fruit in the plant kingdom. Bred in eastern Canada by Howard Dill, Atlantic Giant can reach 1,000 lbs or more! The record is 2,624.6 lbs - updated for 2020! The really big ones look like big orange Volkswagen Beetles. These giants grow on very large plants, with vines up to 50' long, so they require lots of room, full sun, and fertile soil to produce the giant pumpkins. For the largest size, prepare a growing area 20 x 20 feet, and dig down three feet. Fill this with soil mixed heavily with fully composted manure and glacial rock dust. Apply a balanced organic fertilizer at transplant time, and feed the plant every two weeks with liquid kelp or fish fertilizer. Once a fruit begins to grow, remove all female flowers that follow so that there is only one fruit per plant. Consider placing a tarp or board beneath the fruit as it develops in order to shift it once it is fully grown.

West Coast Seeds Dill’s Atlantic Giant Pumpkins Seeds, Per Package
Starting
Sow seeds 2cm (1″) deep. Sow 3 seeds in each spot you want a plant to grow and thin to the strongest plant. Space plants at a minimum of 90-120cm (36-48″) apart in rows 120-180cm (48-72″) apart. If starting transplants indoors, consider using the 12-cell plug inserts.
Timing
Direct sow or transplant in late spring when soil warms up. For transplants, start seeds indoors 4-6 weeks after the last frost date. Try to get the plants into the ground no later than the summer solstice. Optimal soil temperature for germination: 25-35°C (68-95°F). Seeds should sprout in 7-14 days.
Harvest
Like other winter squash, pumpkins are mature when they have coloured up well and their stems are crisp. For the best sugar content, cut the stem about 4cm (2″) or so from the body of the fruit. If the weather is dry, allow the pumpkins to cure in the field for 10 days, or in a warm room for 4-5 days. Bring pumpkins in under cover before rain.
