How To Harvest And Store English Walnuts

To harvest and store English walnuts, you’ll need to wait until the green outer husks split open and the nuts inside are fully mature.
 
You can harvest English walnuts in late summer to early autumn, when the husks begin to crack and fall away from the shell.
 
At that point, the walnuts are ready to be gathered, dried, and stored so they stay fresh for months.
 
If you’ve ever wondered how to harvest and store English walnuts without ending up with moldy or rancid nuts, this guide will walk you through every step.
 
We’ll cover when to harvest English walnuts, how to dry them properly, and the best ways to store English walnuts so they keep their flavor.
 
Let’s dive in.
 

When and How to Harvest English Walnuts

Harvesting English walnuts at the right time is the difference between a sweet, crunchy nut and a bitter, shriveled disappointment.
 
Here’s how to harvest English walnuts the right way.
 

1. Watch for the Husks to Split

English walnuts are ready to harvest when the green outer husk starts to split open on its own.
 
You’ll notice the husk pulling away from the shell, and often the nut will drop to the ground.
 
If you harvest English walnuts too early, the kernel inside will be rubbery and stuck to the shell.
 
So wait for that husk to split, even if it means checking your trees every day.
 

2. Gather Nuts from the Ground

Once English walnuts start falling, gather them promptly.
 
Leaving them on the ground too long invites mold, insects, and squirrels to beat you to the harvest.
 
You can also shake the branches gently to knock loose English walnuts down, then collect them in a bucket.
 

3. Remove the Husks Quickly

After you harvest English walnuts, remove the husks within a day or two.
 
If the husk is still clinging on, you can pry it off with your fingers or a blunt knife.
 
Wear gloves unless you want stained hands, because the husk juice leaves a stubborn brown mark.
 
Once the husks are off, you’re ready to dry the nuts.
 

How to Dry English Walnuts for Storage

You can’t store English walnuts straight off the tree, because the moisture inside will turn them moldy.
 
Drying English walnuts properly takes a few weeks, but it’s the key step that makes long storage possible.
 

1. Spread Them Out to Air-Dry

Lay the husked English walnuts in a single layer on a screen, tray, or newspaper.
 
Put them somewhere warm, dry, and well-ventilated, like a garage, porch, or attic.
 
Turn the nuts every couple of days so they dry evenly and don’t develop mold on one side.
 

2. Give Them Two to Four Weeks

Plan on two to four weeks of drying time for English walnuts.
 
When they’re properly dried, the shells will feel hard and light, and the kernels will rattle slightly inside.
 
You can also crack one open to test it, since a dried English walnut kernel snaps instead of bending.
 

3. Cure Them a Bit Longer

Once dry, let your English walnuts cure in a cool, airy spot for another week or two.
 
This curing step deepens the flavor and evens out any leftover moisture.
 
After curing, your English walnuts are ready for storage.
 

How to Store English Walnuts

Now for the fun part, storing English walnuts so they stay fresh and tasty for as long as possible.
 

1. Keep Them in Their Shells

English walnuts in the shell last much longer than shelled ones.
 
The shell protects the kernel from air and light, which are the two biggest enemies of fresh nuts.
 
So if you can, store English walnuts whole and crack them as you need them.
 

2. Use Airtight Containers

Place your dried English walnuts in airtight containers, like glass jars or sealed plastic bins.
 
Squeeze out as much air as you can before sealing the lid.
 
Label the container with the date so you know how long your English walnuts have been sitting.
 

3. Choose a Cool, Dark, Dry Spot

Store English walnuts in a cool, dark, dry place, ideally between 32°F and 50°F.
 
A pantry, cellar, or refrigerator works well for keeping English walnuts fresh.
 
Avoid spots near the stove or in direct sunlight, since heat makes the oils in English walnuts go rancid fast.
 

4. Freeze for Long-Term Storage

If you want to store English walnuts for a year or more, freezing is your best bet.
 
Pack the dried nuts in freezer-safe bags or containers, then pop them in the freezer.
 
You can freeze English walnuts in the shell or shelled, and they’ll keep beautifully for up to two years.
 
Just thaw them at room temperature before eating so they don’t get soggy.
 

5. Watch for Spoilage

Before using your stored English walnuts, give them a quick sniff and taste test.
 
Fresh English walnuts smell mildly nutty, while spoiled ones smell sharp, bitter, or like old paint.
 
If they taste rancid or look moldy, toss them out and start planning next year’s harvest.
 

So, How Do You Harvest and Store English Walnuts?

You harvest and store English walnuts by waiting for the husks to split, husking the nuts quickly, drying them for several weeks, and then storing them in airtight containers in a cool, dark place.
 
Follow these steps and your English walnuts will stay fresh and flavorful for months, whether you keep them in the pantry or the freezer.
 
Now you know exactly how to harvest and store English walnuts, so you can enjoy your own homegrown crop all year long.
