How To Harvest Walnuts And Store

To harvest walnuts and store them, you need to wait for the right time, remove the hulls, dry them thoroughly, and keep them in a cool, dark place.
 
It sounds like a lot, but it’s actually a simple process once you know the steps.
 
If you’ve ever wondered how to harvest walnuts and store them so they stay fresh for months, you’re in the right place.
 
The key is timing your harvest correctly and getting the moisture level right before you tuck them away.
 
In this post, we’ll walk through when to harvest walnuts, how to harvest walnuts, and the best ways to store walnuts so they last.
 
Let’s dive in.
 

How to Harvest Walnuts: The Step-by-Step Process

 
Learning how to harvest walnuts starts with knowing when they’re ready.
 
If you pick them too early, the kernels won’t be fully formed; too late, and they’ll be moldy or infested.
 
Here’s how to harvest walnuts the right way.
 

1. Wait for the Hulls to Split

 
The best time to harvest walnuts is when the outer green hull starts to split open.
 
This usually happens in late summer to early fall, depending on your climate.
 
When you see the hull cracking and the hard shell peeking through, it’s go time.
 

2. Shake the Tree or Wait for Them to Drop

 
You can harvest walnuts by shaking the branches gently and letting them fall.
 
Or you can simply wait for them to drop on their own, which is often easier.
 
Just don’t leave them on the ground too long, or they’ll get eaten by squirrels or start to rot.
 

3. Remove the Hulls Right Away

 
Once you’ve gathered your walnuts, you need to remove the hulls within a day or two.
 
Hulls left on too long will stain the shell and can cause mold.
 
Wear gloves because the hulls contain juglone, which stains your hands brown for days.
 
You can pop the hulls off by hand or use a dull knife to pry them loose.
 

4. Rinse and Inspect

 
After hulling, rinse the walnuts in a bucket of water.
 
Discard any that float, because that usually means the kernel inside is shriveled or empty.
 
Only keep the ones that sink, as those are the good ones.
 

How to Store Walnuts So They Stay Fresh

 
Now that you know how to harvest walnuts, the next big step is drying and storing them properly.
 
If you store walnuts while they’re still damp, they’ll get moldy fast.
 
Here’s how to store walnuts the right way.
 

1. Dry Them Completely First

 
Before you store walnuts, you have to dry them.
 
Spread them out in a single layer in a cool, dry, well-ventilated area.
 
Let them dry for two to four weeks, turning them occasionally so they dry evenly.
 
They’re ready when the shells feel hard and dry, and you can hear the kernel rattle inside.
 

2. Keep Them in a Cool, Dark Place

 
To store walnuts for short-term use, keep them in a mesh bag or cardboard box in a cool, dark spot.
 
A pantry or basement works well, as long as it’s not too humid.
 
This way, you can store walnuts for a few months without losing flavor.
 

3. Use the Fridge or Freezer for Long-Term Storage

 
If you want to store walnuts for a year or more, the fridge or freezer is your best bet.
 
Shelled walnuts keep well in an airtight container in the fridge for up to six months.
 
For even longer storage, freeze them in a sealed bag or container, and they’ll stay fresh for up to a year.
 
Just make sure they’re completely dry before freezing, or ice crystals will form and ruin the texture.
 

4. Watch for Signs of Spoilage

 
Even when you harvest walnuts and store them properly, they can still go bad.
 
If they smell rancid or taste bitter, toss them out.
 
Walnuts have delicate oils that can turn rancid if exposed to heat, light, or moisture, so always check before you use them.
 

Tips for Harvesting and Storing Walnuts

 
A few extra tips can make the process smoother.
 

1. Harvest Before the First Frost

 
If you wait too long to harvest walnuts, frost can damage the kernels.
 
Aim to harvest walnuts before the first hard freeze for the best quality.
 

2. Don’t Compost the Hulls

 
Walnut hulls contain juglone, which can harm other plants.
 
So don’t toss them in your compost pile if you plan to use it on sensitive plants.
 

3. Label Your Storage Containers

 
When you store walnuts, label the container with the date.
 
That way, you’ll know how long they’ve been sitting and can use the older ones first.
 

So, How Do You Harvest Walnuts and Store Them?

 
To harvest walnuts and store them, you wait for the hulls to split, remove the hulls quickly, dry the nuts thoroughly, and keep them in a cool, dark place or the fridge or freezer for long-term storage.
 
It’s not complicated, but it does take a little patience and attention to detail.
 
Once you get the hang of it, you’ll have a steady supply of fresh walnuts to enjoy all year.
 
So go ahead and harvest walnuts from your trees, dry them well, and store walnuts so they stay tasty for months.
 
You’ll be glad you did when you’re cracking open a fresh, homegrown walnut in the middle of winter.
