Yes, you can store blueberries and blackberries together.
Both berries share similar storage needs, so keeping them in the same container works just fine as long as you follow a few simple rules.
If you’ve been wondering whether storing blueberries and blackberries together is safe, the short answer is yes, and it can actually save you fridge space.
The key is understanding how each berry behaves, because blueberries and blackberries ripen at different speeds and have slightly different textures.
In this post, we’ll cover how to store blueberries and blackberries together, why it works, and the mistakes that can turn your fresh berries into a mushy mess.
Let’s get into it.
Can You Store Blueberries and Blackberries Together?
You can store blueberries and blackberries together, and here’s why it works so well.
1. They Share Similar Temperature and Humidity Needs
The main reason you can store blueberries and blackberries together is that both thrive in cold, humid conditions.
Blueberries and blackberries both store best at around 32–38°F, which is the temperature range of a typical refrigerator.
They also both prefer high humidity, so the crisper drawer is the ideal spot for them.
Since their storage requirements line up almost perfectly, you’re not forcing one berry to suffer for the sake of the other.
2. Neither Berry Is Ethylene-Sensitive in a Harmful Way
Ethylene is a natural gas that some fruits release to speed up ripening.
The good news is that blueberries and blackberries are both low ethylene producers.
This means storing blueberries and blackberries together won’t cause one to over-ripen the other too quickly.
Compare that to something like bananas or apples, which pump out ethylene and can wreck nearby produce.
With berries, you don’t have that problem, so sharing a container is safe.
3. Both Berries Are Delicate but Compatible
Blueberries are firmer, while blackberries are softer and more fragile.
That difference matters, but it doesn’t stop you from storing blueberries and blackberries together.
You just need to handle them gently and avoid piling them too deep.
If you toss them in a big bowl and let them crush each other, the blackberries will bruise first.
But with a little care, they coexist just fine in the same space.
How to Store Blueberries and Blackberries Together the Right Way
Storing blueberries and blackberries together is easy once you know the steps.
Here’s how to do it so both berries stay fresh as long as possible.
1. Keep Them Dry Until You’re Ready to Eat
Moisture is the number one enemy of fresh berries.
Don’t rinse your blueberries or blackberries before storing them.
Washing introduces water into the container, and that trapped moisture encourages mold.
Instead, wait until you’re about to eat them, then give them a quick rinse.
This one habit makes a huge difference when you store blueberries and blackberries together.
2. Pick Through and Remove Damaged Berries
Before you combine them, sort through both batches.
Toss any blueberries or blackberries that are squishy, moldy, or leaking juice.
One rotten berry can spread mold to the whole container fast.
So check each berry, remove the bad ones, and only store the firm, healthy fruit.
3. Use a Shallow Container Lined with Paper Towels
Grab a shallow container or a baking dish rather than a deep bowl.
Line the bottom with a paper towel to absorb excess moisture.
Spread the blueberries and blackberries in a single layer if you can.
If you must stack them, keep it to two layers at most and add another paper towel on top.
This setup is the best way to store blueberries and blackberries together without bruising.
4. Store Them in the Crisper Drawer
The crisper drawer gives you the cool, humid environment both berries love.
Set the drawer to high humidity if your fridge has that setting.
Keep the container loosely covered rather than sealed airtight.
A little airflow helps prevent mold while still holding in moisture.
This is where storing blueberries and blackberries together really pays off.
5. Eat the Blackberries First
Since blackberries are more fragile, they tend to go bad before blueberries do.
So when you store blueberries and blackberries together, plan to eat the blackberries first.
The blueberries will hold up for several more days, giving you a bit of a buffer.
How Long Can You Store Blueberries and Blackberries Together?
When you store blueberries and blackberries together properly, they’ll last about 5 to 7 days in the fridge.
Blueberries can sometimes stretch to 10 days if they’re fresh and dry.
Blackberries are usually best within 3 to 5 days.
If you need more time, freezing is your friend.
Spread the berries on a baking sheet, freeze them individually, then transfer to freezer bags.
Frozen blueberries and blackberries keep for up to a year and work great in smoothies and baked goods.
Common Mistakes When You Store Blueberries and Blackberries Together
A few missteps can ruin your berries even when you do most things right.
1. Washing Before Storing
We mentioned this already, but it’s worth repeating.
Wet berries grow mold quickly, so always store them dry.
2. Sealing Them Airtight
A tightly sealed container traps moisture and ethylene.
That speeds up spoilage instead of slowing it down.
3. Crowding the Container
Piling berries too high crushes the soft ones and blocks airflow.
Keep it shallow and give them room to breathe.
So, Can You Store Blueberries and Blackberries Together?
You can store blueberries and blackberries together, and doing so is a simple way to save fridge space.
Both berries need the same cold, humid conditions, and neither releases enough ethylene to harm the other.
Just keep them dry, sort out the damaged ones, use a paper-towel-lined container, and eat the blackberries first.
Follow those steps and storing blueberries and blackberries together will keep both batches fresh and ready to enjoy.
