I garden in the root zone and canopy of a forest of walnut trees. They are absolutely fine with jugalone. One bed is under the tree now that the tree increased in size. I do lose occasional canes when they are slammed with a baseball sized nut falling 50ft.

I'll also add that the leaves are left to decompose in with the roses. The squirrels are kind enough to plant a walnut under every plant that I grow sometimes two. So the roses are exposed to every part of the trees.

I do need to make up for the nutrition and water that the trees take thou.

Oh thank you! I figured any too close would be needing extra care, but it's great to hear that they shrug off the leaves, roots, and nut hulls (sort of anyway lol).

My garden has been growing alongside/ under black walnut street trees for 112 years. Right now we have an entire bed of roses under one. No problems whatever, as long as, as you said, the roses get light and water. Sometimes the walnuts are so deep that we have to remove them with a shovel. My next door neighbor pays her children 25 cents each to collect them in a bucket.

I thought the problem was with black walnuts only, and not English walnuts. Or is it both types of walnuts we are talking about? Diane

Well that was interesting I looked it up. All walnut and hickory trees produce juglone.

Thanks for this insight. I had been growing all my roses in pots for fear the juglone would kill them but after reading this I will try planting one.

I am glad to see this thread. Black Walnuts & roses have been on my mind because this spring I ordered 5 little Black Walnuts trees. I figured maybe a few wouldnt make it. I have them in pots. I also have 2 Chinese Chestnuts. They are all doing great.

So I have been wondering/kinda worrying about how far I would have to keep the Black Walnuts from the roses. I guess I dont have to worry too much. We have a remnant of an old Pecan Orchard on our property and the pecan trees havent bothered anything.
