How to Kill a Walnut Tree Without Cutting It down

If you want to kill a walnut tree without cutting it down, there are several things you can do. The most common method is to use herbicides. You can either drill holes into the trunk and fill them with herbicide, or you can cut the bark and apply the herbicide to the exposed wood.

There are also chemicals that you can inject into the trunk which will eventually kill the tree. Another method is to girdle the tree, which means cutting through the bark all the way around the trunk. This will prevent nutrients from reaching the leaves and eventually kill the tree.

Finally, you can simply remove all of the leaves from the tree. This will starve it of sunlight and cause it to die.


If you’re looking to kill a black walnut tree, there are a few things you can do. You can cut it down, but this will only work if the tree is small. If the tree is larger, you’ll need to use a chemical herbicide.

You can also try burning the tree, but this isn’t always effective.
