About Dill's Atlantic Giant
Dill's Atlantic Giant is an annual pumpkin / winter squash with orange color, 97–120 in mature height or spread, and a vining/climbing habit. Harvest form or size: potentially hundreds of pounds under specialized culture; ordinary garden results vary widely. Botanically it is Cucurbita maxima Duchesne. Maturity or first bloom: 120-129 Days; germination: 7-10 Days at 75–90 °F. Best for giant pumpkin projects, youth and educational gardens, exhibition growing, and gardeners prepared for intensive management. Grown primarily for size and exhibition rather than ordinary culinary quality.
History and provenance
Dill's Atlantic Giant was developed by Canadian grower Howard Dill from giant pumpkin lines and became the foundation of modern giant pumpkin competition. Changing world-record weights are not treated as permanent cultivar facts. Botanical record: Cucurbita maxima. The broader crop history is kept separate from the documented history of the named variety. Where an exact breeder, introduction date, family story, or cultural attribution cannot be supported by a credible record, repeated claims are not presented as certain. Give runners a planned direction so leaves receive air and fruit can rest on a dry surface. Female flowers need repeated pollinator visits for complete fruit set. Leave fruit on the vine until it reaches full mature color and the rind resists a thumbnail. Cut rather than pull, retain a sound stem, and handle the rind carefully.

Plant during Late Spring. Space plants 48 in apart with 96 in between rows or planting bands.
Provide Full sun, moderate water, and loamy near pH 6.0–6.5. Support: No-Support.
Garden performance and care
Give Dill's Atlantic Giant enough room for its vining/climbing growth. Direct irrigation to the soil, keep developing fruit on dry mulch or boards where rot is common, and leave seed-saving fruit on the plant beyond the eating stage. Expected emergence is 7-10 Days; the listed maturity or bloom timing is 120-129 Days.
Harvest, bloom, and uses
Dill's Atlantic Giant is best for giant pumpkin projects, youth and educational gardens, exhibition growing, and gardeners prepared for intensive management. Harvest form or size: potentially hundreds of pounds under specialized culture; ordinary garden results vary widely. Color at the principal harvest or mature stage: Orange. Grown primarily for size and exhibition rather than ordinary culinary quality.
Saving seed
Seed saving for Dill's Atlantic Giant Select several healthy, true-to-type plants so the saved lot represents the variety rather than one unusually early or large individual. Squash and gourds are insect-pollinated and cross readily with other varieties of the same species. Confirm the species identified for this crop, then isolate by distance or controlled hand pollination. Mark seed fruit and let it reach full biological maturity; summer squash must become large and hard, winter squash must develop full rind color, and luffa or hard-shell gourds must mature well beyond the edible stage. Cure sound fruit before extraction when the crop benefits from curing. Remove, wash, and dry seed to a hard, storage-ready condition. Maintain several representative plants and record species, population, isolation, fruit selection, curing, cleaning, and test date.
Common problems
Watch Dill's Atlantic Giant for cucumber beetles, squash bugs where applicable, aphids, powdery or downy mildew, bacterial wilt, crown rot, poor pollination, and fruit damage on wet soil. Rotate cucurbit crops, provide airflow, water at the root zone, protect young plants before flowering, and remove covers when blossoms need pollinators. Do not work wet vines.
