How Long Can Squash Be Stored

Squash can be stored for anywhere from a few weeks to well over six months, depending on the type you’re dealing with and how you handle it after harvest.
 
Winter squash varieties like butternut, acorn, and spaghetti squash store the longest when kept in the right conditions.
 
Summer squash such as zucchini and yellow squash have a much shorter window because of their thin, tender skins.
 
But how long can squash be stored really comes down to a few key factors, including variety, curing, and storage environment.
 
In this post, we’ll break down how long you can store squash, what affects its shelf life, and the best practices to keep it fresh for as long as possible.
 
Let’s get into it.
 

How Long Can Squash Be Stored? A Breakdown by Type

You can store squash for different lengths of time depending on the variety you have on hand.
 
Here’s a closer look at what to expect so you know exactly how long your squash will last.
 

1. Winter Squash: 3 to 6 Months or More

Winter squash can be stored for three to six months under ideal conditions, and some varieties last even longer.
 
Butternut squash usually keeps for two to three months in a cool, dark spot.
 
Acorn squash tends to store for one to two months.
 
Spaghetti squash holds up well for about two to three months when cured and stored properly.
 
Hubbard squash is a champion of long storage and can last five to six months or longer.
 
The key difference with winter squash is its thick, hard rind.
 
That tough exterior protects the flesh inside and slows down moisture loss, which is why you can store squash of this type for so long.
 

2. Summer Squash: 1 to 2 Weeks

Summer squash like zucchini, yellow squash, and pattypan doesn’t store nearly as long.
 
You can typically store squash of this type for about one to two weeks in the refrigerator.
 
You can sometimes store squash of the summer variety for a little longer if you keep it in a crisper drawer with proper humidity.
 
But the thin skin means moisture escapes fast, and soft spots develop quickly.
 
So if you’re wondering how long can squash be stored when it’s a summer variety, the answer is much shorter than its winter cousins.
 

What Determines How Long Squash Can Be Stored

Several factors affect how long you can store squash, and getting these right makes a huge difference.
 
Here’s what to pay attention to so your squash lasts as long as possible.
 

1. Curing Is Essential

Curing is the process of letting winter squash sit in a warm, well-ventilated area for about one to two weeks after harvest.
 
This step hardens the skin and heals any small cuts or scratches.
 
If you skip curing, your squash won’t store nearly as long, and you may end up with rot within a few weeks.
 
Proper curing is one of the biggest reasons some people can store squash for six months while others see spoilage in a month.
 

2. Temperature and Humidity Matter

The ideal temperature to store squash is between 50°F and 55°F (10°C to 13°C).
 
Anything colder can damage the flesh, and anything warmer speeds up ripening and decay.
 
Humidity should stay around 50% to 60%, which is dry enough to prevent mold but not so dry that the squash shrivels.
 
A cool, dark basement, root cellar, or pantry works great for this.
 

3. Variety Plays a Big Role

Some squash varieties are simply built to last longer than others.
 
Hubbard, butternut, and turban squash are known for their long shelf life.
 
Delicata and acorn squash have thinner skins and don’t store as long.
 
So when you ask how long can squash be stored, the answer always depends on which type you’re dealing with.
 

Tips to Store Squash So It Lasts Longer

Want to get the most out of your harvest?
 
Follow these tips so you can store squash with confidence and waste less food.
 

1. Keep Them Dry and Off the Floor

Moisture is the enemy of long-term squash storage.
 
Wipe down your squash with a dry cloth before storing and make sure they’re completely dry.
 
Place them on a shelf or piece of cardboard rather than directly on a cold concrete floor.
 

2. Don’t Stack Them

Squash needs airflow around it to stay fresh.
 
If you stack them on top of each other, you create pressure points where rot can start.
 
Arrange them in a single layer with a little space between each one.
 

3. Check Regularly for Spoilage

Even with perfect storage, one bad squash can ruin the bunch.
 
Check your stash every week or two and remove anything with soft spots, mold, or a funky smell.
 
This keeps the rest of your squash in good shape.
 

4. Refrigerate Summer Squash

Summer squash should go straight into the fridge after harvest.
 
Store it in a plastic bag with a paper towel to absorb excess moisture.
 
Don’t wash it until you’re ready to use it, since extra moisture speeds up spoilage.
 

So, How Long Can Squash Be Stored?

Squash can be stored for a few weeks to six months or more, depending on the variety and how well you cure and store it.
 
Winter squash lasts the longest when kept cool, dry, and well-ventilated.
 
Summer squash needs refrigeration and should be used within a couple of weeks.
 
Get the curing and storage conditions right, and you’ll be able to store squash for months without losing flavor or texture.
