Can Potatoes And Squash Be Stored Together

Potatoes and squash should not be stored together because they have very different storage needs.
 
Potatoes like it cool, dark, and slightly humid, while winter squash prefers warm, dry conditions.
 
If you’ve been wondering whether potatoes and squash can be stored together, the short answer is no, and it mostly comes down to temperature and humidity.
 
When you store potatoes and squash together, one of them will suffer, and often both will spoil faster than they should.
 
In this post, we’ll look at why potatoes and squash can’t be stored together, what each one actually needs, and how to store them properly so they last.
 

Why Potatoes and Squash Can’t Be Stored Together

Storing potatoes and squash together simply doesn’t work, and here’s why.
 

1. They Need Opposite Temperatures

The biggest reason you can’t store potatoes and squash together is temperature.
 
Potatoes store best between 45°F and 50°F (7°C to 10°C).
 
Winter squash, on the other hand, likes it warmer, ideally between 50°F and 55°F (10°C to 13°C).
 
That’s a small gap, but it matters over weeks and months of storage.
 
If potatoes get too warm, they sprout and shrivel.
 
If squash gets too cold, it turns mushy and loses flavor fast.
 
So when you store potatoes and squash together, you’re forcing one of them into conditions it hates.
 

2. Humidity Needs Don’t Match

Humidity is another reason potatoes and squash can’t share the same space.
 
Potatoes prefer high humidity, around 90% to 95%.
 
Squash likes things drier, closer to 50% to 70%.
 
Put them together and you create a lose-lose situation.
 
In high humidity, squash develops mold and rot on its skin.
 
In low humidity, potatoes dry out, wrinkle, and lose their firmness.
 
You can’t keep potatoes and squash together without one of them paying the price.
 

3. Ethylene Gas Speeds Up Spoilage

Here’s something many people don’t know: ethylene gas.
 
Certain produce releases this natural gas as it ripens, and squash is one of them.
 
Potatoes are sensitive to ethylene, and when they’re exposed to it, they sprout faster.
 
So when you store potatoes and squash together, the squash may be quietly pushing your potatoes to sprout.
 
Sprouted potatoes soften, wrinkle, and don’t last nearly as long.
 
That alone is a good reason to keep potatoes and squash apart.
 

4. Airflow and Curing Needs Differ

Potatoes and squash also need different airflow and curing before storage.
 
Potatoes need to be cured for about two weeks in a cool, humid, dark spot before going into long-term storage.
 
Squash needs to be cured for one to two weeks in a warm, dry, well-ventilated area.
 
Curing helps both develop tougher skins and heal minor cuts.
 
If you try to store potatoes and squash together during this stage, neither gets what it needs.
 
Poor curing leads to faster spoilage, mold, and soft spots.
 
So can potatoes and squash be stored together during curing?
 
No, they really can’t.
 

How to Store Potatoes and Squash Separately

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

1. Storing Potatoes the Right Way

Keep potatoes in a cool, dark, humid place, like a cellar or a ventilated bin.
 
Use a breathable container like a cardboard box, paper bag, or mesh sack.
 
Never store potatoes in plastic, because trapped moisture causes rot.
 
Keep them away from onions, apples, and squash, since those all release ethylene.
 
Check your potatoes every couple of weeks and remove any that have sprouted or softened.
 
Stored this way, potatoes can last several months.
 

2. Storing Squash the Right Way

Keep winter squash in a warm, dry spot with good air circulation.
 
A pantry shelf, a cool closet, or a ventilated basket all work well.
 
Don’t stack squash too high, and make sure they aren’t touching each other.
 
This prevents any one squash from spreading rot to the others.
 
Keep squash away from potatoes, onions, and other ethylene-sensitive produce.
 
Stored properly, many winter squash varieties last two to six months.
 

3. Watch for Signs of Spoilage

Even with perfect storage, check your crops regularly.
 
For potatoes, watch for sprouts, soft spots, green patches, and a musty smell.
 
For squash, look for soft spots, mold, and a dull or mushy stem.
 
Remove any spoiled items immediately so they don’t affect the rest.
 
This is the simple habit that keeps your harvest going strong.
 

So, Can Potatoes and Squash Be Stored Together?

Potatoes and squash should not be stored together because they need different temperatures, humidity levels, and airflow to stay fresh.
 
Their ethylene sensitivity makes things worse, since squash can cause potatoes to sprout faster.
 
If you’ve been asking whether potatoes and squash can be stored together, now you know the answer is a firm no.
 
Keep potatoes cool, dark, and humid.
 
Keep squash warm, dry, and well-ventilated.
 
Do that, and both will last far longer than they ever would side by side.
