Atlantic Giant Pumpkin is an heirloom, open-pollinated pumpkin variety that is sure to win a blue ribbon at the county fair! This variety can easily produce giant pumpkins averaging 200 lbs, but can get larger in optimal growing conditions. While these giant pumpkins are not good for eating, many do enjoy them for carving and decorating. For best results, grow Atlantic Giant Pumpkin in deeply-tilled, well-drained soil. Soils high in organic matter will tend to produce larger fruits. Give plants plenty of room.
Pumpkins may be direct-seeded or transplanted, although we highly recommend direct seeding. To ensure a good stand, we recommend planting seeds every 12″ along the intended row. Once plants emerge, thin plants to one every 2 feet. Pumpkins can be susceptible to plant diseases like downy mildew and powdery mildew if leaves receive excess moisture. As a result, we recommend using drip irrigation on winter squash to reduce plant moisture and feed plants more effectively. During periods of heavy rainfall, using a fungicide like Liquid Copper can help to alleviate disease pressure as well.
Pumpkins are a crop that will produce a one-time harvest at the end of the growing season. They should be harvested when plants die back and the fruits obtain their full color. Stem hardness is also an indication of fruit maturity. Once stems harden, fruits are ready for harvest using a set of pruning shears. Pumpkins can be stored in a cool, dry place for several months, depending on variety and sugar content. Once fruits are harvested, remove the plants from the garden to prevent any fungal spores from overwintering and becoming a problem in future years. Proper crop rotation is extremely important with all pumpkin varieties to reduce disease and pest pressure.
