How To Harvest And Store Walnuts

To harvest and store walnuts, you need to know when they’re ready, how to cure them properly, and the best ways to keep them fresh for months.
 
The process isn’t complicated, but timing is everything if you want to harvest and store walnuts that taste great and last a long time.
 
If you’ve been wondering how to harvest and store walnuts the right way, this guide will walk you through each step.
 
In this post, we’ll cover when to harvest walnuts, how to harvest and store walnuts after picking, and the best conditions for storing walnuts so they stay fresh.
 
Let’s dive in.
 

When to Harvest Walnuts

Knowing when to harvest walnuts is the first step to a successful crop.
 
If you pick too early, the nuts won’t develop properly and can taste bitter.
 
If you wait too long, squirrels, birds, and mold may beat you to them.
 
Here’s how to tell the timing is right to harvest walnuts.
 

1. Watch for the Hull to Split

The clearest sign it’s time to harvest walnuts is when the outer green hull starts to split open.
 
This usually happens in late summer to early fall.
 
When you see the hull cracking and pulling away from the shell, it means the nut inside is mature.
 
That’s your signal to start planning how to harvest walnuts.
 

2. Check for Fallen Nuts

As walnuts ripen, they naturally drop from the tree.
 
When you notice nuts falling freely, it’s a good time to harvest walnuts.
 
You can also shake the branches gently to encourage ripe nuts to fall.
 
Just don’t wait too long after they drop, because the hull can rot and stain the shell.
 

3. Test the Shell Hardness

Pick one nut and try to crack it.
 
If the shell is hard and the nut inside is plump, it’s ready to harvest walnuts.
 
If the shell is still soft or the nut is shriveled, give it another week or two.
 

How to Harvest Walnuts

Once you know when to harvest walnuts, the next step is actually getting them off the tree and preparing them.
 
Here’s how to harvest walnuts without damaging them.
 

1. Gather the Nuts

You can harvest walnuts by picking them up from the ground or shaking them from the tree.
 
Spread a tarp or sheet underneath to make collection easier.
 
Wear gloves because the hulls contain juglone, which can stain your hands brown for days.
 

2. Remove the Hulls

After you harvest walnuts, you need to remove the outer hull.
 
You can do this by hand, with a knife, or by rubbing them together.
 
Do this within a day or two of harvesting, because the hulls get slimy and moldy fast.
 

3. Wash and Inspect

Rinse the nuts in water to remove any remaining hull bits and debris.
 
Toss out any nuts with cracks, holes, or dark spots.
 
When you harvest walnuts, only keep the clean, intact ones for storing.
 

4. Cure the Walnuts

Curing is the most important step after you harvest walnuts.
 
Spread them in a single layer in a cool, dry, well-ventilated area.
 
Let them dry for two to four weeks, turning them occasionally.
 
Proper curing prevents mold and helps the nuts develop their full flavor.
 
When they’re ready, the shells should feel dry and brittle, and the nut inside should snap when you crack it.
 

How to Store Walnuts

After you harvest and cure walnuts, storing them properly keeps them fresh for months.
 
Here’s how to store walnuts so they don’t go rancid or stale.
 

1. Keep Them in the Shell

Storing walnuts in the shell is the easiest way to keep them fresh.
 
The shell protects the nut from air and moisture.
 
Place them in a breathable bag or basket and keep them in a cool, dry spot.
 
When you store walnuts this way, they can last up to a year.
 

2. Shell and Refrigerate

If you’ve shelled your walnuts, refrigerate them in an airtight container.
 
When you store walnuts in the fridge, they stay fresh for about six months.
 
Keep them away from strong-smelling foods, because walnuts absorb odors easily.
 

3. Freeze for Long-Term Storage

To store walnuts for more than a year, freezing is your best bet.
 
Place shelled or unshelled walnuts in freezer-safe bags or containers.
 
Squeeze out as much air as possible before sealing.
 
When you store walnuts in the freezer, they keep well for up to two years.
 

4. Label and Rotate

Always label your containers with the date you harvest and store walnuts.
 
Use the oldest ones first to avoid waste.
 
This simple habit makes it easy to keep track of how long you’ve been storing walnuts.
 

So, How Do You Harvest and Store Walnuts?

To harvest and store walnuts, start by watching for split hulls and fallen nuts.
 
Then harvest walnuts promptly, remove the hulls, wash them, and cure them for a few weeks.
 
Finally, store walnuts in a cool, dry place, the fridge, or the freezer depending on how long you want to keep them.
 
Hope this post has helped you learn how to harvest and store walnuts so you can enjoy your crop for months to come.
