Knowing how to store squash over the winter is really about controlling temperature, humidity, and airflow.
 
When you get those three things right, your squash can last well into the colder months without turning soft or moldy.
 
If you want to store squash over the winter successfully, you need to start with good fruit and treat it gently.
 
In this post, we’ll look at how to store squash over the winter, which types last longest, and the mistakes that shorten shelf life.
 
Let’s get to it.
 

How to Store Squash Over the Winter

The way to store squash over the winter is to cure it first, then keep it cool, dry, and well ventilated.
 
Here’s what those steps look like in practice.
 

1. Choose the Right Squash

Not all squash store equally well over the winter.
 
Winter squash like butternut, acorn, spaghetti, Hubbard, and kabocha are the best candidates for long storage.
 
These have thick, hard rinds that protect the flesh inside.
 
If you want to store squash over the winter, pick varieties known for keeping well.
 
Skip any squash with soft spots, cracks, or punctures because those will rot fast.
 

2. Cure the Squash First

Curing is the secret step most people skip when they store squash over the winter.
 
It hardens the skin and heals small scratches so the squash can last for months.
 
To cure squash, keep it somewhere warm and dry around 80 to 85°F with good airflow for 7 to 14 days.
 
A sunny porch or a warm garage works nicely.
 
Don’t wash the squash before curing, since moisture invites mold.
 
Once the skin feels tough and the stem looks dry, your squash is cured and ready.
 

3. Leave the Stem On

Always leave an inch or two of stem attached when you store squash over the winter.
 
That stem acts like a cork and keeps moisture from escaping and bacteria from getting in.
 
If the stem breaks off, the squash will spoil much faster.
 
So handle your squash carefully and never snap the stem off.
 

4. Keep Them Cool and Dry

The ideal conditions to store squash over the winter are 50 to 55°F with about 50 to 70 percent humidity.
 
A cool basement, root cellar, or unheated pantry is perfect.
 
If it’s too warm, the squash will lose moisture and get stringy.
 
If it’s too cold, chilling injury can cause brown spots and mushy flesh.
 
And damp air is the enemy, so never store squash somewhere humid.
 

5. Give Them Space and Airflow

When you store squash over the winter, don’t pile them on top of each other.
 
Place them in a single layer on shelves or in crates so air can move around each one.
 
You can also sit them on newspaper or cardboard to soak up any excess moisture.
 
Keep them away from onions, apples, and other produce that releases ethylene gas.
 
That gas speeds up ripening and shortens how long your squash will keep.
 

6. Check Them Regularly

Part of learning how to store squash over the winter is checking on them every couple of weeks.
 
Look for soft spots, mold, or shriveling.
 
If you find a bad one, remove it right away so it doesn’t spoil the rest.
 
A squash that’s starting to go soft is best used immediately rather than stored.
 

Which Squash Store Best Over the Winter

Some squash hold up better than others when you store squash over the winter.
 

1. Butternut Squash

Butternut is a favorite because it stores squash over the winter beautifully for two to three months.
 

2. Hubbard Squash

Hubbard has a very hard rind, so it can store squash over the winter for up to six months.
 

3. Acorn and Spaghetti Squash

These store well for about one to two months when kept cool and dry.
 

4. Delicata Squash

Delicata has a thinner skin, so it won’t store squash over the winter as long, usually just a few weeks.
 

Common Mistakes When You Store Squash Over the Winter

Even folks who know how to store squash over the winter slip up on a few things.
 

1. Washing Before Storage

Washing adds moisture, which leads to mold, so wait until you’re ready to cook.
 

2. Stacking Them Up

Piling squash traps moisture and causes bruising, so keep them in a single layer.
 

3. Storing Near the Furnace

Warm, dry air pulls moisture from the squash, so keep them in a cool spot.
 

4. Using the Fridge Too Long

A fridge is too cold for long storage and can damage the texture of your squash.
 

So, How Do You Store Squash Over the Winter?

You store squash over the winter by curing it first, then keeping it cool, dry, and well ventilated.
 
Pick hardy varieties, leave the stem on, and give each squash its own space.
 
Check them often and pull out any that start to soften.
 
Do all that, and you’ll store squash over the winter with ease and enjoy homegrown flavor for months.
