You prepare walnuts from the tree by harvesting them when the husks split open and then curing the nuts properly so they dry without spoiling.
If you’ve ever stared at a walnut tree loaded with green fruit and wondered how to prepare walnuts from the tree, you’re in the right place.
Learning how to prepare walnuts from the tree is really just a few simple steps: harvest, hull, wash, and cure.
In this post, we’ll walk through how to prepare walnuts from the tree so you can enjoy fresh, homegrown nuts all winter long.
Let’s get to it.
When to Harvest Walnuts From the Tree
Knowing when to harvest walnuts from the tree is half the battle.
Here’s how to tell your walnuts are ready.
1. Watch for Splitting Husks
When the green outer husk starts to split and pull away from the shell, your walnuts are ready to harvest.
This usually happens in early autumn, depending on your climate and the variety of walnut you’re growing.
If you pick walnuts from the tree before the husks split, the nuts inside won’t be fully developed.
2. Let Some Fall Naturally
Another sign that it’s time to prepare walnuts from the tree is when you see them dropping to the ground on their own.
You can shake the branches gently to knock loose nuts down, or simply gather the ones that have already fallen.
Just don’t wait too long, because walnuts left on the ground can get moldy or get taken by squirrels.
3. Toss Out the Bad Ones
Not every walnut you collect will be worth keeping.
Discard any with holes, dark spots, or a shriveled, wormy look.
These are signs of insect damage or rot, and they won’t cure well.
How to Hull and Wash Walnuts From the Tree
Once you’ve harvested your walnuts, the next step in how you prepare walnuts from the tree is hulling and washing them.
1. Remove the Outer Husks
If the husks haven’t fallen off on their own, peel them away by hand or with a sturdy glove.
Black walnut husks stain everything they touch, so wear old clothes and gloves you don’t mind ruining.
This is the messiest part of preparing walnuts from the tree, but it’s worth the effort.
2. Rinse the Nuts Thoroughly
After hulling, rinse your walnuts in a bucket of clean water to remove any leftover husk bits and juice.
Good nuts will sink, while hollow or bad ones will float.
Scoop out the floaters and toss them, then drain the rest.
3. Don’t Soak Too Long
A quick rinse is all you need when you prepare walnuts from the tree.
Soaking them for hours can let water seep into the shell and cause mold during curing.
Curing Walnuts From the Tree
Curing is the most important step in how to prepare walnuts from the tree, because it dries them out and deepens their flavor.
1. Spread Them Out to Dry
Lay your walnuts in a single layer on screens or a clean tarp in a cool, dry, well-ventilated spot.
Keep them out of direct sunlight and turn them every few days so they dry evenly.
2. Give Them Time
Curing walnuts from the tree usually takes two to four weeks.
They’re ready when the shells feel light and brittle and the nut inside rattles a little when you shake it.
3. Store Them Properly
Once cured, store your walnuts in mesh bags or containers that allow airflow.
Keep them in a cool, dark place, or freeze them for longer storage.
Properly cured walnuts from the tree can last up to a year.
So, How Do You Prepare Walnuts From the Tree?
You prepare walnuts from the tree by harvesting them when the husks split, hulling and rinsing them, and then curing them until they’re dry and flavorful.
Preparing walnuts from the tree isn’t complicated, but it does take patience.
Follow these steps and you’ll have a stash of fresh homegrown walnuts to enjoy for months.
