Answer: First start with the soil. To grow big pumpkins, you need to amend the soil heavily with compost and composted manure. Cover the area with black plastic about 2 weeks before planting to heat up the soil. Then 4 weeks before your last frost date, start the seed indoor, under lights. When ready to set them outside, cover the young seedling with a floating row cover to protect them from the might cold and wind. Keep the row cover on until the vines begin to run. Water well, and fertilize weekly with a complete fertilizer such as Miracle Grow. Let only 2 pumpkins set per vine and prune off all the others. By fall you should have some real prizewinners in your garden.
