Sugar pie pumpkins are small round sweet pumpkins perfectly suited to be used for pumpkin pie, not just for their flavor, but because one pumpkin is about the right size for one pie. Approx. 15 seeds.
Pumpkins like warm soil and are very sensitive to frost. So don’t be in a rush to plant early in spring. Wait until danger of frost has passed and soil has warmed to about 70 F, or about 2 weeks after the last frost date.
Unless you are trying to grow a long-season variety in an area that gets early frosts, there’s really no need to start pumpkins inside. Instead, direct seed 1 to 1 1/2 inches deep into hills (which warm and drain earlier in the season) or rows. Sow 4 to 5 seeds per hill. Space hills about 4 to 8 feet apart, depending on the size of the vine. (Even some of the mini-fruited pumpkins grow on very large vines.) When the plants are 2 to 3 inches tall, thin to 2 to 3 plants per hill by snipping off unwanted plants without disturbing the roots of the remaining ones. In rows, sow seeds 6 to 12 inches apart in rows 6 to 10 feet apart. Snip off plants to thin to one plant every 18 to 36 inches.
If you need to start plants early, plant inside in 2- to 3-inch pots or cells 3 to 4 weeks before transplanting outside. Sow 3 or 4 seeds per pot and thin to one or two plants by snipping off the weaker plants to avoid damaging the roots of those that remain. Harden off by cutting back on water and reducing temperature before transplanting. Plant transplants out in the garden at the same final spacings above after all danger of frost has passed.
