Cucurbita moschata 'Waltham Butternut'

vegetable

Butternut is the most popular winter squash, a tan, bell-shaped fruit with dense, sweet, deep-orange flesh, a small seed cavity, and a smooth rind that is easy to peel. The vigorous vines ripen fruit in roughly 85 to 110 days, and butternut is one of the best-keeping squash, sweetening in storage and lasting for months.

🌾 Harvest & storage

Harvest when the rind has turned solid tan, is hard enough to resist a fingernail, and the stem is dry and corky, ideally a couple of weeks past full color, cutting with a stub of stem attached. Cure butternut at about 80 to 85F for ten days to harden the rind and convert starch to sugar, then store at 50 to 60F, where it keeps three to six months.
