About Butternut Squash

Butternut squash is the most popular winter squash — sweet, smooth, and superb for storage. A vigorous vining plant that needs warm weather and room to sprawl.

Direct sow after last frost or start indoors 3-4 weeks earlier. Harvest when skin turns tan and hard. Cure 1-2 weeks in a warm spot before storing in a cool dry place.
