How to Store Winter Squash
Store winter squash in a cool, dark, and dry environment with plenty of airflow. A temperature between 50°F and 55°F is the sweet spot for keeping them firm for months; anything colder risks chilling injury, while heat will cause them to soften prematurely.
Curing is the secret to longevity
Before moving squash into long-term storage, ensure they are fully cured so the skin is hard and woody. If you can't easily pierce the rind with your thumbnail, it is ready to put away.

Hardening the Rind
Keep harvested squash in a warm, sunny spot for 7 to 10 days to toughen the skin and seal the stem. This drying phase prevents rot and protects the flesh inside.
The method.
Inspect for damage
Check for soft spots, deep nicks, or puncture wounds. Any squash with broken skin should be set aside to be cooked within a few days, as it will not keep in storage.
Clean the surface
Wipe away loose soil with a dry, soft cloth. Do not wash the squash with water, as excess moisture encourages mold.
Position for airflow
Place the squash in a single layer on wooden shelves or in crates. Ensure they do not touch each other, which prevents mold from spreading if one squash begins to decline.
Monitor storage conditions
Keep them away from direct sunlight and keep the humidity levels low. Check the stored squash once a week; if one feels soft or develops a smell, remove it immediately to save the rest.
When it doesn't go to plan.
Never carry a squash by the stem; if the stem snaps off, the protective seal is broken and the squash will spoil within weeks.
Basements, closets, or unheated pantries are usually better than a damp cellar or a warm kitchen.
Do not store winter squash next to ripening apples or bananas, as the ethylene gas they release will cause the squash to deteriorate faster.
The ones that keep coming up.
Should I refrigerate my winter squash?
No. Refrigerators are too cold and too humid, which causes the interior flesh to degrade and the skin to become susceptible to rot.
How long will they last?
Hard-rinded varieties like Hubbard or Acorn can last 3 to 6 months depending on the conditions, while thinner-skinned varieties like Delicata should be consumed within 1 to 2 months.
