Hi, I'm new to this forum. I have a question about whether roses generally are susceptible to juglone toxicity, the toxin produced by walnut trees. I have a small property with several walnut trees on neighboring land, close to and overhanging a sunny bank where I would like to plant a rambler. Any idea if it will be affected? Thanks!

Welcome to the rose forum! Are there other things currently growing where you want to plant your rose? If there are, there is a good chance the rose will be okay there too.

I have several roses growing close to a black walnut tree. I think they're bothered more by the shade it casts than by the juglone.

Hi Akinney, to the Rose Forum!

From my experience, I found that the decomposing leaves of walnut to be quite unpleasant for roses. Not sure what it is, but the roses would stop growing and a bit of chlorosis on the foliage.

I used to garden near black walnut trees. I saw Rosa multiflora growing next to black walnut trees. I am not sure about other rose varieties. My roses were not close to the black walnut trees.
