About Winter Squash

Winter squash (butternut, acorn, spaghetti) are the long-storing hard-skinned squash you plant in spring and harvest in fall. Vigorous, sprawling, and highly productive.

Direct sow or start indoors 4 weeks before last frost; transplant after frost. Give vines room (6-8 ft) or a trellis. Harvest when skin is hard and you can't dent it with a fingernail. Cure in a warm place for 1-2 weeks for long storage.
