Winter Squash Seeds,
Sweet Dumpling

Plant Sweet Dumpling squash after the last frost when the soil has warmed to at least 70 F, as these plants are very sensitive to frost. Start seeds indoors 3-4 weeks before the last frost if needed, and transplant seedlings once conditions are suitable. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Sow seeds 1/2-1 inch deep directly in the garden or in pots if starting indoors. Space plants 18-36 inches apart in rows or hills. If transplanting, harden off seedlings before planting them outdoors. Don’t let transplants become rootbound, and be careful not to disturb roots while transplanting.

Provide consistent moisture, especially during dry spells, and use mulch to retain soil moisture. Sweet Dumpling squash is a heavy feeder, so regular fertilization with a balanced fertilizer is recommended. Keep an eye out for common pests like squash bugs and manage them with organic pest control methods.

• There are four main species of squash: Cucurbita maxima, C. pepo, C. moschata, and C. mixta. They will not cross pollinate with each other, so it is possible to grow one of each species for seed saving without worrying about cross pollination.
• If you are planning to grow several varieties of more than one species, you can bag the blossoms and hand pollinate to avoid crossing.
• Whether it is a summer or winter squash, you must let the fruit completely mature before extracting the seeds, and cure for at least two weeks.
• Scoop the seeds, place them in a bucket, and add just enough water to cover. Let sit at room temperature to ferment for two days before rinsing off the pulp.
• Lay seeds out to dry on newspaper or paper plates.
• Stored in a cool, dry place, seeds will remain viable for up to four years.
