Winter Squash Storage

When is winter squash ready to harvest?

Squash is ready when the rind is hard enough that a fingernail does not easily dent it, the skin color is deep and dull, and the stem has begun to dry and cork. Harvest before a hard frost, and bring in any fruit that has been touched by frost for immediate use.

Use pruners to cut the fruit with a few inches of stem. Never carry squash by the stem, because a broken stem opens a way for rot.

Ripe time varies by variety, so check the seed packet or a variety guide. Keep notes on the variety and planting date, because the same variety can ripen differently from year to year depending on the weather. A little stem left on is protection, so do not trim it close, and handle every fruit as though it were fragile.

• Dull deep color
• Dry, corky stem

Do I need to cure squash?

Many varieties benefit from a short curing period in a warm, dry, ventilated place, which hardens the skin and heals small wounds. Some varieties, such as acorn squash, do not need curing and may store poorly if cured. Check guidance for your variety.

Do not wash squash before storing. Wipe off soil with a dry cloth and keep fruit dry.

Ask your extension office for curing guidance suited to your climate. A short curing period can help many varieties, but a long one in heat can cause shriveling, so watch the fruit and follow the guidance for your variety. Mark any fruit with small cuts or soft areas and set it aside to eat first.

Where and how should I store it?

Store in a cool, dry, ventilated place, off the floor and not touching each other, with the stems intact. A shelf or slatted crate works. Avoid places where temperature swings or where moisture or frost can form.

Do not store with apples, which give off gas that speeds ripening and decay. A basement shelf, a closet or an insulated room may do.

Ask your extension office for temperature and humidity targets for your variety. Think about your own house before choosing a spot. A spare bedroom closet, a cool hallway shelf or an unheated room can work better than a damp basement. Check the shelf for drips from pipes or windows, and keep it clear of mice and other pests.

How long does it last?

Storage life depends on the variety. Butternut and hubbard types generally store longer than acorn types, and quality declines over time. Check your seed company's notes and local extension guidance.

Eat the thin-skinned and smaller ones first, and save the thick-skinned varieties for later in winter.

Taste improves in some varieties after storage, as starches turn to sugars. Expect some variety to be best eaten by midwinter, while others may keep into spring, and plan your meals around that order. Keep a simple list of what is on the shelf so you know when to start using the longer keepers.

How do I check on stored squash?

Look at the stored squash every week or two, checking for soft spots, mold, leaks or sunken areas. Remove any that show problems, since decay spreads. Use soft ones right away, after cutting away damaged parts.

If a squash is rotten through or smells bad, discard it.

Keep a note of which varieties kept longest in your conditions. A quick look under each squash for a soft or discolored patch where it touched the surface is worth the effort, since decay often starts on the underside.

Can I preserve it another way?

If you cannot store it all, freeze cooked, mashed squash following a tested source. Canning squash is a special case: tested guidance for pumpkin and winter squash calls for cubed pieces, not puree, and requires a pressure canner. Use a current tested source and never improvise.

Dried squash is also possible with tested guidance.

Your extension office can send current publications on each option. Cooked squash should be cooled promptly and refrigerated or frozen, and not left on the counter for long.

What mistakes should I avoid?

Harvesting too early, carrying by the stem, washing before storage, storing in a damp or warm spot and stacking fruit are the typical problems. Another is storing squash with damage that is not yet visible.

Handle squash like eggs. A small bruise today becomes a rotten spot in a month.

Keep the best-looking fruit for storage, and eat the rest. Compost any squash you cannot use, or feed it to livestock only if your extension office confirms that it is suitable for the animals you keep.
