Butternut is the beloved winter squash (Cucurbita moschata) with a long tan neck, small seed cavity, and sweet, nutty, deep orange flesh. These squash seeds grow 2–5 lb fruits that store for months and are prized for roasting, soups, and purees. Its dense, smooth texture and reliable sweetness make butternut the most popular winter squash for home kitchens.

Who it's for

For cooks who want a versatile, long-storing squash and gardeners looking for a productive, easy-to-grow winter crop.

How & when to plant

Direct-sow after the last frost when soil reaches 70°F, or start indoors 2–3 weeks early. Sow seeds 1 inch deep and space plants 24–36 inches apart in rows 6–8 feet apart. Full sun and rich, well-drained soil support the long-season vines. Grows as an annual in USDA zones 3–10.

Harvest

Ready about 100–110 days from sowing. Harvest when the skin is fully tan and hard; cure in a warm spot for 1–2 weeks to deepen sweetness and improve storage.

Benefits & uses

Excellent roasted, in soups, risottos, and purees. Cured fruit keeps 3–6 months in a cool, dry place, giving you homegrown squash well into winter.

FAQ

Butternut is a sweet, nutty winter squash with dense orange flesh, excellent for roasting, soups, and purees, and it stores for months after harvest.
It matures in about 100-110 days. Harvest when the rind is a solid tan, hard, and the stem has dried, before the first hard frost.
Cure harvested squash in a warm, dry spot for about 10-14 days, then store in a cool, dry place where it keeps well for two to three months or longer.
Plant in hills of 2-3 plants spaced 4-6 feet apart in full sun. The long vines spread widely, so give them plenty of room or a strong trellis.
Sow directly after the last frost once soil is 65-70F, or start indoors 3-4 weeks early. This long-season squash needs the full warm season to mature.
Yes, these are open-pollinated, non-GMO seeds, so you can save seed from your best-flavored squash for next year's garden.
The vines sprawl, so give each plant room or grow them at bed edges to ramble.
Stored cool, dry, and sealed in the original packet, the seeds stay viable for a couple of years or more, with the best germination in the first year or two.
