" Build a small mound of dirt and plant the seed 1–2 inches (2.5–5.1 cm) deep. The hill helps improve soil drainage and allows the sun to heat the soil faster, speeding up germination.  Plant 2 or 3 seeds within a few inches of one another, in case one doesn't sprout for some reason. It doesn't matter which end of the seeds points up. If the seeds are viable, they will grow either way. If your pumpkin variety grows along creeping vines, space the hills in the same row 12 ft (3.7 m) apart, and space the rows 6 to 10 ft (1.8 to 3 m) apart, depending on variety size. "Bush-type" varieties that grow on shorter vines need 8 ft (2.4 m) of space in all directions. If you composted the soil before planting, you can skip this step. If not, add a thin layer of compost or mulch in the areas where you planted seeds. The compost will help keep weeds out and nourish the seeds. With proper care, the pumpkin plants should sprout within about a week.
