How to Sow Pumpkins
SOW in average soil in full sun in spring after all danger of frost. Sow 4-6 seeds about 3" apart in hills 4-6 apart. Cover with 1" of fine soil; firm lightly and keep evenly moist. If the fruit will not be very heavy, you can train the vines on a trellis to save space. Give large-fruited pumpkins lots of room to ramble.
How to Grow Pumpkins
Seedlings emerge in 7-14 days. Thin seedlings to 2-3 per hill when they are 1-2" high. Pumpkins need plenty of water throughout their long growing season. Like their close relatives, cucumbers and melons, they produce male and female flowers on the same plant. You can hand-pollinate the flowers as you would for cucumbers if the bees are not pollinating them. If you are trying to grow extra-large pumpkins, allow only one fruit per plant to mature. Do not plant pumpkins and other squash family crops in the same spot 2 years in a row.
Harvesting Pumpkins
Pumpkins are ready to harvest when the rinds are hard and the proper shade of orange or white for the cultivar. If a light frost kills the vines, cut the fruits from the vines--with 3-4" of stem attached--before they are damaged by heavy frost. Pumpkins can be stored for weeks or months in a warm, dry place at 50-60°F. Use the flesh for baked pies, soups, casseroles, muffins, or bread. Or cook pumpkin as you would winter squash, and serve as a side dish. Roast the seeds for a tasty snack. The flowers are also edible and can be dipped in batter and deep-fried, stir-fried, or sauteed.
Companion Plants
Beds of vigorous, sprawling pumpkin vines can be bordered by corn, towering pole beans, sunflowers and other trellised or vine vegetables.
