Is Black Walnut Killing Your Plants

“Black walnut kills plants.”

I first heard this statement many years ago.  Occasionally, I still hear some version of this claim:  Black walnut engages in warfare by releasing a chemical into the soil.  This chemical kills or inhibits the growth of plants.

But is this entirely true?  Does black walnut actually kill plants?

Some people say yes.  Other people say no.

In a brand-new video, I share several key findings from scientific studies and personal observations that shed some light on this controversial topic.

You can watch the video here.

Thanks for reading and watching, and thanks for your continued support!
