Can Potatoes And Squash Be Stored Together

Potatoes and squash should not be stored together.
 
While both are hearty storage crops that can last for months under the right conditions, their ideal environments are completely different.
 
If you’ve been wondering whether you can store potatoes and squash together to save space, the short answer is no.
 
Potatoes need cool, dark, and humid conditions, while squash prefers warm, dry, and well-ventilated spots.
 
Putting them in the same bin creates a clash of needs that shortens the shelf life of both.
 
In this post, we’ll explore why potatoes and squash can’t be stored together, what happens if you try, and how to store each one properly.
 
Let’s dive in.
 

Why Potatoes and Squash Can’t Be Stored Together

The reason potatoes and squash can’t be stored together comes down to their totally opposite storage requirements.
 
Here’s what’s going on under the surface.
 

1. They Need Opposite Humidity Levels

Potatoes thrive in high humidity, ideally around 90 to 95 percent.
 
Squash, on the other hand, needs dry air, usually around 50 to 60 percent humidity.
 
If you store potatoes and squash together, one of them will suffer.
 
The humid environment potatoes love will cause squash to grow mold and rot.
 
Meanwhile, the dry conditions squash needs will make potatoes shrivel and wrinkle.
 
There’s simply no humidity level that keeps both happy.
 

2. Their Temperature Preferences Clash

Potatoes store best between 40 and 50°F.
 
Winter squash, however, prefers temperatures between 50 and 60°F.
 
If you store potatoes and squash together at potato-friendly temps, the squash will suffer chilling damage.
 
Chilly conditions break down the squash’s cell walls, leaving it mushy and flavorless.
 
Store them at squash-friendly temps, and your potatoes will sprout prematurely.
 
Either way, storing potatoes and squash together means one crop starts to go bad faster.
 

3. Ethylene Gas Speeds Up Spoilage

Here’s something many gardeners don’t realize: potatoes and squash both release ethylene gas as they breathe.
 
When you store potatoes and squash together, that gas builds up in a confined space.
 
Ethylene triggers faster ripening, sprouting, and eventual decay.
 
The potatoes will sprout sooner, and the squash will soften and develop off flavors.
 
That’s one more reason why these two crops should never share a storage space.
 

4. Airflow Needs Are Different

Squash needs good air circulation to stay dry and prevent rot.
 
Potatoes prefer a more enclosed, humid environment to keep from drying out.
 
If you store potatoes and squash together, you can’t give both what they need.
 
The airflow that keeps squash healthy will dry out your potatoes, and the enclosure that keeps potatoes plump will trap moisture around your squash.
 
It’s a lose-lose situation.
 

5. Pests and Diseases Spread Easily

When you store potatoes and squash together, any pest or disease problem in one crop can quickly jump to the other.
 
Potatoes can attract rodents, and squash can develop fungal issues in the wrong conditions.
 
A single rotten squash can also release moisture that speeds up potato spoilage.
 
Keeping them separate reduces the risk of one bad item ruining your entire harvest.
 

What Happens If You Store Potatoes and Squash Together?

If you go ahead and store potatoes and squash together, here’s what you can expect.
 

1. Squash Develops Mold and Rot

The high humidity potatoes need creates a breeding ground for mold on squash.
 
You’ll notice soft spots, fuzzy patches, and a mushy texture within weeks.
 
Once rot sets in, it spreads fast and can ruin your whole squash crop.
 

2. Potatoes Sprout and Shrivel

The warmer, drier conditions squash prefer will cause potatoes to sprout early.
 
Sprouted potatoes lose flavor and texture, and they release even more ethylene.
 
Meanwhile, the dry air pulls moisture from the potatoes, leaving them wrinkled and soft.
 

3. Both Crops Spoil Faster

The bottom line is that storing potatoes and squash together shortens the shelf life of both.
 
Instead of months of storage, you might get only a few weeks before things go bad.
 
That’s a waste of a good harvest you worked hard to grow.
 

How to Store Potatoes and Squash Separately

Since you can’t store potatoes and squash together, here’s how to store each one properly.
 

1. Storing Potatoes the Right Way

Keep potatoes in a cool, dark place at 40 to 50°F with high humidity.
 
A root cellar, a ventilated bin, or a paper sack in a dark corner works well.
 
Avoid washing them before storage, and never store them near onions or apples.
 

2. Storing Squash the Right Way

Cure winter squash for 10 to 14 days in a warm, dry spot, then store at 50 to 60°F.
 
Keep them on a shelf with good airflow, not stacked on top of each other.
 
Check them regularly and remove any that show signs of softness or mold.
 

So, Can Potatoes and Squash Be Stored Together?

Potatoes and squash should not be stored together because their temperature, humidity, and airflow needs are complete opposites.
 
Trying to store them together only leads to moldy squash, sprouted potatoes, and a shorter shelf life for both.
 
Your best bet is to give each crop its own dedicated space with the right conditions.
 
That way, you’ll enjoy your homegrown potatoes and squash for months instead of weeks.
 
Happy storing.
