I'm about ready to rip them out. Please don't rip out your roses, says UC master gardener Carol Bowden. They just need pruning and, perhaps, fertilizer. Since they did well the first few years, you must be taking good care of them. Roses like fertilizer when growth begins in the spring and after each blooming period ends.
Canes generally bloom heavily for only two or three seasons.
Attach them loosely to the fence in a horizontal pattern. Remove branchlets that point down or out, leaving ones that point up with about 6 inches between them. Shorten these to about 6 inches. As the tall, straight shoots develop on your plants, bend horizontally and tie them to the fence. It's also a good idea to attend one of the many pruning clinics scheduled this winter.
