When to Grow

Sow seeds outdoors after the last frost date when soil temperatures have reached at least 70°F. In shorter-season regions, start seeds indoors 2–4 weeks before the last frost and transplant when danger of frost has passed. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Plant seeds 1 inch deep in fertile, well-draining soil. Space plants 24 to 36 inches apart in rows, allowing good airflow and sun exposure. If starting indoors, use biodegradable pots and transplant seedlings after hardening off. Keep soil evenly moist throughout germination and early growth for best results.

How to Grow

Water deeply and consistently, focusing at the base of the plant to reduce disease risk. Mulch to retain soil moisture and suppress weeds. Fertilize every 3–4 weeks with compost or organic vegetable fertilizer. Harvest fruits when young and tender, around 6–8 inches long, to encourage ongoing production and peak flavor. Monitor for common squash pests and use organic controls as needed.

How to Save Seeds

Note that there are four different 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 save seeds from several varieties of the same species, you can bag the blossoms and hand pollinate to avoid crossing.

  • Allow fruits to mature fully on the vine until the skin is hard and color deepens.
  • Harvest mature squash and cure in a warm, dry space for 2–3 weeks.
  • Cut open the fruit and scoop out seeds.
  • Rinse seeds to remove all pulp and residue.
  • Spread seeds out in a single layer to dry in a well-ventilated area for 2–3 weeks.
  • Store dried seeds in a labeled, airtight container in a cool, dry place.
