400 to 500 pounds is the norm for these heavily ribbed beauties, the Dill's Atlantic Giantic Pumpkin. Rough-skinned and beautifully ribbed, the pumpkins just keep going and going at an astonishing rate. You've got to try it for yourself!
Pumpkins are best direct sown outdoors after all danger of frost has passed in the spring and the soil has warmed. They can be sown indoors (at a temperature of 70 to 75 degrees F) 2 to 3 weeks before planting out, but direct sowing is recommended.
For Halloween pumpkins, sow seeds from late May in northern regions to early July in very southern areas. Be aware that planting too early may lead to your pumpkins spoiling before Halloween arrives.
Pumpkins are exceptionally easy to grow, given adequate space and patience! Sow the seeds outdoors when danger of frost is past, or start indoors in peat pots. Plant the seedlings (or thin to) 3 to 5 feet apart.
