Can roses get rust? I seem to remember reading this about 12 years ago.
At the time I'd planted a few precious roses (which I think got rust on
them, hazy memory), I had rust on my hollyhocks - spraying did help but I
didn't want to use too many chemicals so I got rid of the hollyhocks. I
haven't had rust on the roses since then. Last year I grew some more
hollyhocks from seed and they were soon covered in rust. The roses weren't
affected this time, but a mallow did get it. Does anyone else know if
roses can get rust?
