How to Store Winter Squash
Winter squash needs warmth and time to cure before it can become a dependable winter store. Harvest mature fruits with hard skins, an intact stalk and no bruising or soft spots. Once cured, squash keeps best indoors in a cool, frost-free, airy place rather than in a cold damp shed.
Best storage conditions
After curing, store winter squash at around 10-15 degrees C in a dry, airy, frost-free room with moderate humidity. A cool spare room, porch or insulated garage is often better than an unheated shed, which may become too cold or damp. Keep fruits in the dark or subdued light, but never in a sealed box. Arrange them with space around every fruit and keep them off cold concrete floors.
How long it keeps
Well-cured winter squash commonly keeps for 3-6 months, though keeping time depends greatly on variety and ripeness. Inspect fruits weekly and use any that develop a soft patch, mould, shrivelling or a damaged stalk. Once cut, refrigerate the pieces and use them promptly or freeze them.
Storage methods
Harvest before frost, cutting rather than pulling and leaving a short, intact stalk. Wipe away dry soil, but do not wash the fruit. Cure for 1-2 weeks in sun and warmth during settled weather, or in a warm, airy, frost-free place under cover until the skin has hardened. Then move fruits to shelves, slatted trays or lined boxes in a cool indoor store. Keep each squash separate so a hidden soft spot cannot spread. Turn and inspect them weekly. Never store damaged, immature or wet fruits with the sound crop.
Preserving
Roast or steam the flesh, mash it and freeze in portions for soups, sauces and baking. Raw peeled cubes can also be blanched, cooled and frozen in a chest freezer. Squash is suitable for chutney, jam and other preserves when a trusted recipe is followed. Dry thin cooked slices until leathery for a compact pantry ingredient.
Tips
The stalk is part of the seal: fruit with a broken or missing stalk should be eaten first. Avoid carrying squash by its stalk. A fruit that feels light, hollow or soft is not a keeper. Label varieties, as storage life varies widely. Never expose stored squash to frost, which damages the flesh even when the skin looks sound.
