You can make dye with black walnuts by using the husks that surround the shell.
 
If you’ve ever wondered how to make dye with black walnuts, you’re in for a real treat because those messy green husks hold a powerful natural pigment.
 
This is one of the oldest and most reliable natural dyes you can create right from your own backyard.
 
In this post, we’ll walk through how to make dye with black walnuts step by step, from gathering the husks to setting the color on your fabric.

How to Make Dye With Black Walnuts: The Basics

Learning how to make dye with black walnuts starts with understanding what part of the tree actually gives you color.
 
The secret is in the husk, not the hard shell inside.
 
Those round green balls that drop from the tree in late summer and early fall are exactly what you need.
 
And here’s why this process works so well:
 

1. Black Walnut Husks Are Loaded With Juglone

The husks of black walnuts contain a compound called juglone.
 
Juglone is a natural chemical that acts as a powerful dye.
 
It bonds easily with protein fibers like wool and silk, and it also works on plant fibers when you use a mordant.
 
That’s the magic behind how to make dye with black walnuts that actually lasts.
 

2. The Color Range Is Amazing

When you make dye with black walnuts, you get a rich palette of browns.
 
Depending on the fabric and how long you soak it, you can achieve anything from a light tan to a deep, dark chocolate brown.
 
That’s why so many homesteaders love knowing how to make dye with black walnuts.
 
You’re basically getting free, earthy color straight from nature.
 

3. The Husks Are Easy to Gather

If you have a black walnut tree nearby, gathering husks is the easiest part.
 
Just collect them after they fall to the ground.
 
The husks should still be green or slightly yellow, and they’ll start turning black as they age.
 
Wear gloves because black walnut husks will stain your hands for days.
 
Trust me on that one.
 

Step-by-Step: How to Make Dye With Black Walnuts

Now let’s talk about the actual process of how to make dye with black walnuts so you can get beautiful results every time.
 

1. Gather and Prepare the Husks

Collect the husks and remove them from the hard shells.
 
You can use them fresh or dry them for later.
 
If you’re wondering how to make dye with black walnuts using dried husks, just rehydrate them in water overnight before you start.
 

2. Simmer the Husks

Place the husks in a large pot and cover them with water.
 
Bring the water to a gentle simmer.
 
Never let it boil hard because that can muddy the color.
 
Simmer for about an hour, or longer if you want a darker shade.
 
The water will turn a deep, tea-like brown, which tells you the dye is ready.
 

3. Strain the Dye Bath

Remove the pot from the heat and let it cool a bit.
 
Strain out the husks using a fine mesh strainer or cheesecloth.
 
Now you have a beautiful black walnut dye bath ready for your fibers.
 
This is the heart of how to make dye with black walnuts.
 

4. Add Your Fabric or Yarn

Pre-wet your fabric or yarn so the dye absorbs evenly.
 
Submerge it in the dye bath and let it soak.
 
For a light tan, soak for an hour.
 
For a deep brown, let it sit overnight or even for a few days.
 
The longer you wait, the darker it gets.
 

5. Use a Mordant for Best Results

If you want your color to last, use a mordant like alum or vinegar.
 
This helps the dye bind to the fibers.
 
When you make dye with black walnuts, a mordant makes a huge difference in colorfastness.
 

Tips for Success When You Make Dye With Black Walnuts

Here are a few extra pointers to keep in mind when you make dye with black walnuts.
 

1. Don’t Use Aluminum Pots

Aluminum can react with the juglone and change your color unexpectedly.
 
Stick with stainless steel or enamel pots.
 

2. Ventilate Your Space

The smell of simmering black walnut husks is strong.
 
Open a window or work outdoors if you can.
 

3. Be Careful With Juglone

Juglone can be toxic to plants and some animals.
 
Don’t pour your leftover dye bath on your garden.
 

4. Test on Scrap Fabric First

Always test a small piece before dyeing a big project.
 
This helps you see exactly how the color will turn out.
 

So, How Do You Make Dye With Black Walnuts?

You make dye with black walnuts by simmering the husks in water and soaking your fabric in the resulting dark liquid.
