How to Grow Pumpkins From Seeds in Winter

Pumpkins are loaded with beta-carotene.

While some gardeners grow pumpkins for food, others grow them in order to participate in giant-pumpkin-growing contests in many agricultural areas. Pumpkins require a long, frost-free growing period -- from 95 to 120 days when planted from seed. If you live in an area with a short growing season, start your pumpkin seeds indoors, after the last frost in the winter.

Things You'll Need

• Peat pellets
• Container with lid
• Heat mat

Instructions

1. Place the peat pellets in a container that is large enough for them to expand when they are wet.

2. Pour enough water over the peat pellets to cover them. The pellets will expand.

3. Press the seed into the top of the pellet and push it down 1/4 inch.

4. Place the heat mat in an area that receives bright light, but not direct sun, and set it to 75 degrees Fahrenheit.

5. Cover the container and place it on the heat mat set. Make sure the pellets remain moist, but not saturated.

6. Remove the cover from the container and turn off the heat mat when the pumpkin seeds sprout. Allow them to remain in the brightly lit area and keep the pellet moist.

7. Wait until the soil temperature outdoors is 75 degrees F. You can measure the soil temperature with a soil thermometer, available at large gardening centers.

8. Place the container holding the seedlings outdoors in a shady area. Gradually give them increasing amounts of sunshine over the course of a week, until they are in full sun all day. Plant them into the garden at that time.
