Deformed rose leaves, chemical or virus? #417322
Asked July 27, 2017, 3:52 PM EDT
I have 4-5 different rose bushes in a berm that are not right...two almost dead, and others beginning to have this leaf damage on different canes.
three photos rose bush one, has severely little new cane growth, severely distorted leaves, and one rose! Rose bush 2, no new cane growth, very damaged leaves in clusters, Rose bush 3, a climber, with very damaged wisps of leaves at the bottom and middle, dwarfed and thinner leaves, and then normal leaves. a person at O'Tooles said he thought it was chemical damage. Another says Rose Rosette.

To find the most appropriate individual to answer your question, what county in Colorado do you reside? Thanks! Ruth
I am in Jefferson County...at border of Denver and Jefferson, near Bear Creek.
I am reading other comments on Rose Rosette posted on this site...and am aware that my "deformed leaf growth", though some look like "brooms" are not red at all, they are light green. Maybe this means some other problem. I am looking forward to your analysis. Anonymous is really Robbie.
Dear Robbie,
We have not yet confirmed rose rosette in the Denver Metro area. The damage is consistent with herbicide injury - possibly glyphosate injury. Your plants may or may not survive.
