If you’ve got a black walnut tree dropping its fruit all over your yard, you might be wondering what to do with black walnuts off the tree.
 
Yeah, those messy green orbs can seem like a nuisance, but they’re actually a valuable resource if you know how to handle them.
 
In this post, we’ll cover the best things to do with black walnuts off the tree, including how to harvest, process, and use them safely.
 
Let’s get to it.
 

What to Do with Black Walnuts Off the Tree: Top Uses

 
When you’re figuring out what to do with black walnuts off the tree, you have plenty of options.
 
Here are the most practical and rewarding ways to put them to good use.
 

1. Harvest and Eat the Nutmeats

 
The most obvious thing to do with black walnuts off the tree is to harvest the nuts inside for eating.
 
Black walnuts have a bold, earthy flavor that’s perfect for baking, ice cream, and savory dishes.
 
But you can’t just crack them open right away.
 
You need to remove the hulls, wash the nuts, and cure them for a few weeks to develop their flavor.
 
Once cured, crack them with a hammer or a specialized nutcracker, then pick out the nutmeats.
 
It’s a bit of work, but the payoff is delicious.
 

2. Make Natural Dye from the Hulls

 
Another great thing to do with black walnuts off the tree is to use the hulls for natural dye.
 
Those green husks are packed with juglone, a compound that creates a rich brown dye.
 
You can simmer the hulls in water to make a dye bath for fabric, yarn, or even wood.
 
Just be careful—juglone stains skin and clothing, so wear gloves and old clothes.
 
This is a favorite among crafters and homesteaders looking for natural colorants.
 

3. Use the Shells for Crafts and Abrasives

 
After you’ve extracted the nutmeats, don’t toss the hard shells.
 
What to do with black walnuts off the tree shells?
 
You can crush them and use them as a gentle abrasive for polishing metal or cleaning tough surfaces.
 
They also work great in craft projects, like making decorative mulch or filling sachets.
 
Some people even use them as a natural landscaping material.
 

4. Compost or Mulch the Remains

 
If you’re not up for processing, you can simply compost black walnuts off the tree.
 
But here’s the catch: black walnut hulls and leaves contain juglone, which can harm some plants.
 
So avoid adding them to compost that you’ll use on sensitive garden plants like tomatoes or peppers.
 
Instead, create a separate compost pile or use them as mulch around juglone-tolerant plants like hostas or daylilies.
 

How to Process Black Walnuts Off the Tree Safely

 
Before you dive into what to do with black walnuts off the tree, you need to process them properly.
 
Here’s how to do it without staining your hands or wasting your time.
 

1. Hull Them Quickly

 
The green hulls start to rot soon after they fall, so gather them fast.
 
You can stomp on them with boots, run them through a corn sheller, or use a hammer.
 
Just make sure to wear gloves because the juice stains deeply.
 

2. Wash and Cure the Nuts

 
After hulling, rinse the nuts in a bucket of water and discard any that float—those are usually bad.
 
Then spread them out in a single layer in a cool, dry, well-ventilated area.
 
Let them cure for 2 to 4 weeks, stirring occasionally, until the shells are hard and dry.
 

3. Store Them Properly

 
Once cured, store black walnuts off the tree in mesh bags or breathable containers.
 
Keep them in a cool, dark place, and they’ll last for up to a year.
 
You can crack them as needed for fresh nutmeats.
 

Creative Ideas for Black Walnuts Off the Tree

 
Beyond the basics, there are some fun and unexpected things to do with black walnuts off the tree.
 

1. Make Black Walnut Ink

 
You can boil hulls to create a dark, permanent ink for calligraphy or art projects.
 
It’s a traditional method that artists still use today.
 

2. Create Natural Wood Stain

 
The same dye bath can stain wood a beautiful deep brown.
 
Just brush it on and let it dry for a rustic finish.
 

3. Feed Wildlife

 
If you don’t want to process them, leave some black walnuts off the tree for squirrels, deer, and birds.
 
They’ll appreciate the snack, especially in winter.
