One dozen pumpkin seeds for growing giant big max pumpkins.
- Pumpkins do best when the seeds are planted directly in the ground.
- If your growing season is very short, seed indoors in peat pots about 2 to 4 weeks before last spring frost. Be sure to harden off before transplanting.
- Wait until the plant soil is 70ºF or more before sowing seeds. Optimum soil temperature is 95ºF. Pumpkins are very sensitive to the cold.
- Plant seeds in rows or “pumpkin hills,” which are the size of small pitcher mounds. With hills, the soil will warm more quickly and the seeds will germinate faster. This also helps with drainage and pest control.
- Prepare the hills in advance with an abundance of old manure dug deep into the ground (12 to 15 inches). If you don’t have manure, loosen the soil and mix in a 2- to 4-inch layer of compost
- Plant the seeds 1 inch deep into the hills (4 to 5 seeds per hill). Space hills 4 to 8 feet apart.
- Your plants should germinate in less than a week with the right soil temperature (70 degrees F) and emerge in 5 to 10 days.
- 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.
