Can You Store Potatoes And Squash Together

You can store potatoes and squash together, but only if you get the conditions exactly right.
 
Honestly, this is one of those questions where the answer isn’t a simple yes or no, because both of these vegetables have specific needs that don’t always overlap perfectly.
 
If you’ve ever wondered whether you can store potatoes and squash together without one ruining the other, you’re in the right place.
 
In this post, we’ll look at whether storing potatoes and squash together actually works, what conditions each one needs, and how to keep both fresh for as long as possible.
 

Can You Store Potatoes and Squash Together?

Yes, you can store potatoes and squash together, but there’s a catch.
 
The two vegetables actually prefer slightly different environments, so putting them in the same bin without any thought can shorten their shelf life.
 
Here’s the thing: potatoes like it cool, dark, and slightly humid.
 
Squash, on the other hand, likes it cool, dark, and dry.
 
That difference in humidity is the main reason storing potatoes and squash together can be tricky.
 
If the air is too humid, your squash can get moldy or mushy.
 
If the air is too dry, your potatoes can shrivel up and lose their firmness.
 
So while you can store potatoes and squash together, you need to find a middle ground that keeps both happy.
 

1. They Have Different Humidity Needs

Potatoes need around 90 to 95 percent humidity to stay firm and avoid shriveling.
 
Winter squash, like butternut or acorn, prefers humidity closer to 50 to 70 percent.
 
That gap is why storing potatoes and squash together in the same airtight container can be a problem.
 
Too much moisture in the air invites rot on your squash.
 
Too little moisture dries out your potatoes.
 

2. Temperature Preferences Are Close but Not Identical

Potatoes store best between 45 and 50°F.
 
Most winter squash also does well between 50 and 55°F.
 
So the temperature range is close enough that you can store potatoes and squash together without too much trouble.
 
Just avoid anything below 45°F, because cold temps turn potato starches into sugar and make them taste oddly sweet.
 
And squash doesn’t love the cold either, since chilling can cause it to decay faster once you bring it back to room temperature.
 

3. Ethylene Gas Isn’t a Big Issue Here

Some fruits and veggies release ethylene gas, which speeds up ripening in neighboring produce.
 
Potatoes do give off a small amount of ethylene, and squash is not especially sensitive to it.
 
This means ethylene isn’t the main reason you’d avoid storing potatoes and squash together.
 
The bigger concern is always moisture and airflow, not gas.
 

4. They Can Share Space If You Separate Them

Here’s a practical trick: you can store potatoes and squash together in the same general area, but keep them in separate containers or bins.
 
That way, each one gets its own microclimate.
 
Put potatoes in a breathable paper bag or a crate lined with newspaper.
 
Keep squash on a shelf or in a shallow box where air can move around it freely.
 
This setup lets you store potatoes and squash together without either one suffering.
 

Best Conditions for Storing Potatoes and Squash Together

If you’re going to store potatoes and squash together, you need to nail the basics.
 
Here’s what to focus on so both veggies stay fresh for weeks instead of days.
 

1. Keep It Dark

Light turns potatoes green, which creates a compound called solanine that’s not good to eat.
 
Squash also lasts longer in the dark because light can degrade its skin and flavor.
 
A dark pantry, a cellar, or a closet works well for storing potatoes and squash together.
 

2. Aim for Cool, Not Cold

You want a cool spot that stays between 45 and 55°F.
 
A garage, a basement, or a root cellar is ideal.
 
Just don’t put them in the fridge, because the cold is too harsh for both potatoes and squash.
 

3. Allow Air Circulation

Never seal potatoes and squash together in a plastic bag.
 
Trapped moisture is the enemy here, and it will cause mold on squash and sprouting on potatoes.
 
Use open crates, mesh bags, or baskets so air can move around them.
 

4. Check Them Regularly

One bad squash can ruin the whole batch.
 
So if you’re storing potatoes and squash together, check them every week.
 
Remove anything soft, moldy, or shriveled right away.
 
This keeps the rest of your stash in good shape.
 

Common Mistakes When Storing Potatoes and Squash Together

Even if you can store potatoes and squash together, a few missteps can ruin the whole plan.
 

1. Washing Before Storage

Never wash potatoes or squash before storing them.
 
Extra moisture on the skin invites mold and rot.
 
Brush off dirt instead and let them stay dry.
 

2. Stacking Squash on Top of Potatoes

Squash bruises easily, and potatoes can poke into their skin.
 
Keep them side by side, not piled on top of each other.
 

3. Using Airtight Containers

Sealed bins trap ethylene and moisture, which speeds up spoilage.
 
Breathable storage is always better when storing potatoes and squash together.
 

4. Ignoring Temperature Swings

Fluctuating temperatures cause condensation, and condensation leads to rot.
 
Keep your storage spot steady and you’ll get weeks of freshness.
 

So, Can You Store Potatoes and Squash Together?

You can store potatoes and squash together, but you need to manage humidity, temperature, and airflow carefully.
 
The two vegetables have slightly different needs, so keeping them in separate containers within the same cool, dark space is the smartest approach.
 
If you get the conditions right, storing potatoes and squash together works just fine and saves you space.
 
Just keep them dry, cool, and well ventilated, and check on them often.
 
Do that, and both your potatoes and squash will last for weeks.
