I am in what I think is Zone 9, about 50 miles north of San Francisco, in an area of cool nights and foggy mornings. Out of 160+ roses, I have only ever had to remove one due to rust: Climbing Dainty Bess. And, just for the record, this rose was somewhat mis-treated this past season by having several pots of plants gathered around its base, decreasing the airflow. Gophers reached critical mass this past year and plants were dug up and potted to protect them until they can be replanted in gopher baskets; unfortunately it seems that trying to deal with one affliction may have led to another. Since I posted my intention to remove this rose, I have reconsidered. I am going to give it another season. I have pruned it very seriously, cleaned up the ground underneath, and will probably (eeeeek) spray with copper and add another inch or two of soil over the old. If it misbehaves next season, I will dig it out and pot it and see if another location is better for it. It is such a beautiful rose and I have already had it in this spot for at least 10 years, soI am just gonna give it a bit more care before giving it the shovel.
