Do my roses have Verticillum Wilt?
In the last couple of years I have had a number of roses that, apparently healthy, have suddenly had a cane wilt, turn brown, then die completely. In some cases the plant died, in others the plant survived. I put out a thread about this but didn't receive any plausible answers as to the problem. I recently heard about Verticillum Wilt and it sounds as though it may be the culprit. Can any of you experts tell me about it? What does one do about it? Are there organic solutions to the problem? Where I lost roses this way I didn't replant with roses.
As a non-rose addendum, do oaks get the disease? I've seen oaks on our property that showed similar sudden dieback.
Thanks for the help!
