Will Deer Eat Black Walnut Trees

Deer will eat black walnut trees, especially the young saplings, fresh buds, and tender leaves.

 

While mature black walnut trees are usually too tough for deer to bother with, the younger growth is a different story entirely.

 

If you’ve been asking yourself, “will deer eat black walnut trees?” the short answer is yes, but there are some important nuances to understand.

 

In this post, we’ll explore why deer eat black walnut trees, what parts they target, and how you can protect your trees if you want them to survive.

 

Let’s get into it.

 

Why Deer Will Eat Black Walnut Trees

Deer will eat black walnut trees because they’re always on the lookout for nutritious, easy-to-reach food sources.

 

And young black walnut trees happen to fit that description perfectly.

 

1. Young Saplings Are Tender and Tasty

The main reason deer will eat black walnut trees is that young saplings are incredibly tender.

 

When a black walnut tree is just a few years old, its stems and leaves are soft enough for deer to nibble on without much effort.

 

Deer are browsers by nature, meaning they prefer to eat leaves, twigs, and buds from woody plants rather than grazing on grass.

 

So a young black walnut sapling is basically a buffet for them.

 

2. Deer Love the Buds and Leaves

Deer will eat black walnut trees because the buds and leaves are packed with nutrients.

 

In early spring, when other food sources are scarce, those fresh green buds are one of the first things to emerge.

 

And deer know it.

 

The leaves of a black walnut tree are also rich in protein and fiber, which are essential for a deer’s diet.

 

So if you’ve got a black walnut tree with low-hanging branches, don’t be surprised if you catch a deer snacking on it.

 

3. Black Walnut Trees Aren’t Toxic to Deer

Unlike some plants that are poisonous to wildlife, black walnut trees aren’t toxic to deer.

 

In fact, deer can eat black walnut trees without any ill effects.

 

The juglone compound found in black walnut trees, which is toxic to many other plants and some animals, doesn’t seem to bother deer.

 

So deer will eat black walnut trees freely, and they’ll keep coming back for more.

 

4. Deer Prefer Them Over Other Food Sources

When given the choice, deer will often eat black walnut trees over other available vegetation.

 

That’s because black walnut leaves and buds are more palatable than many other woody plants.

 

And since deer are creatures of habit, once they find a black walnut tree they like, they’ll return to it again and again.

 

So if you have black walnut trees on your property, you might notice deer making a beeline for them.

 

What Parts of Black Walnut Trees Do Deer Eat?

Deer will eat black walnut trees, but they don’t eat every part equally.

 

Here’s a breakdown of what they target most:

 

1. Leaves

Deer will eat the leaves of black walnut trees, especially the younger, tender ones.

 

They’ll strip the leaves from low-hanging branches and saplings.

 

2. Buds

The buds are a favorite for deer.

 

They’ll eat them in early spring before the leaves fully open.

 

3. Twigs and Stems

Deer will also eat the twigs and stems of young black walnut trees.

 

They’ll browse on them throughout the year, but especially in winter when other food is scarce.

 

4. Bark

Deer will sometimes eat the bark of black walnut trees, especially in late winter.

 

But they usually only do this when other food sources are hard to find.

 

How to Protect Black Walnut Trees from Deer

If you want to keep deer from eating your black walnut trees, you’ve got a few options.

 

1. Fencing

The most effective way to stop deer from eating black walnut trees is to put up a fence.

 

A fence that’s at least 8 feet tall will keep deer out.

 

2. Tree Guards

For young saplings, tree guards are a simple solution.

 

Wrap them around the trunk to protect the bark and lower branches from deer.

 

3. Repellents

Deer repellents can also help.

 

Spray them on the leaves and buds to make them less appealing to deer.

 

4. Plant Alternatives

If deer are a big problem in your area, you might consider planting trees that deer don’t like.

 

But if you’re set on black walnut trees, you’ll need to take steps to protect them.

 

So, Will Deer Eat Black Walnut Trees?

Deer will eat black walnut trees, especially the young saplings, buds, and leaves.

 

While mature trees are usually safe, younger ones are at risk.

 

If you want to keep your black walnut trees safe, you’ll need to take steps to protect them.
