I received a 2 qt Icy Drift from New Life Nursery in August (only nursery I could find that carried it). When moving my potted roses off the deck for the season to prepare to put them in the unheated garage, I noticed narrow leaves at the end of some new growth. The only time I have seen leaf strapping is with herbicide damage and RRD. Herbicide damage is very unlikely considering the time of year, all surrounding potted roses are fine, and the protected location. Even though I do not see any other concerning symptoms, I am hesitant to overwinter it in the garage with the other roses if this is early RRD.

What are your thoughts? What would you do?
