The term “Winter Squash” refers to squash that can be stored over the winter to become part of the winter food stock for eating.

They require longer growing time than summer squashes, and are generally harvested in the fall.

They have hard rinds (sometimes called “shells”) which allow this long storage, but which also makes most of them very hard to cut into.

Winter squashes will generally be from the Cucurbita maxima or Cucurbita moschata species, as compared to summer squashes, which will generally be from the Cucurbita pepo species. There are exceptions, such as the winter squashes acorn squash and spaghetti squash which are Cucurbita pepo. And, there are some squashes which can either be harvested early for eating as a summer squash, or let fully mature to be classed and used as a winter squash.

Winter squashes tend to have yellow to orange flesh. The deeper the orange colour, the more beta-carotene there is in them (which is a precursor of Vitamin A.)

Some winter squashes need to be “cured” first before going into cold storage. Curing involves letting them sit in a warm place (room temperature is fine) for a week or two. Varieties such as acorn, delicata and sweet dumpling, however, should go straight into cold storage.

Many winter squashes sweeten up in storage, as their starches convert to sugars.

Winter squashes are ready to harvest when the shell is hard enough that you can’t press a fingernail into it, but they must be harvested before a hard frost. To harvest for storage, leave part of the stem on.

Storage Hints

Winter squashes need to stored uncut in a cool, dry place, between 7 to 13 C (45 and 55 F), but not in the refrigerator.

Freezing: Wash. Don’t peel. Cut into, remove seeds. Chop into small pieces. Boil, steam or bake until soft. Let cool. Scrape flesh from rind. Package and freeze.

To can: Canning winter squash requires a pressure canner. See: Canning Pumpkin and Squash.
