Identifying and Recovering from Glyphosate Damage on Roses

A rose bush that bloomed well last year now shows classic glyphosate (Roundup) injury: tiny, clustered leaves along the stems. This distinctive "witch's broom" growth is a hallmark of glyphosate exposure, whether from spray drift on a windy day or residue in an unwashed sprayer. Unfortunately, once a rose shows these symptoms, it rarely recovers and will likely die.

The best course is to remove the damaged plant and replace it next season. To prevent future accidents, dedicate separate sprayers for herbicides and other garden products, and avoid spraying on breezy days. Glyphosate damage is irreversible, but it's also a clear diagnostic sign that helps avoid repeat mistakes.
