My white roses have turned pink and the leaves have gone yellow and limp. They look more like dog roses now. Do I need to dig it up or can it be saved? Could it have been pruned back too hard? It was such a lovely bush.
Hmmmm... Sounds like a grafted and rose and the top part of the rosebush, the desired part, has died over winter. The hardy root stock it was grafted to is now taking over. I would dig it out and get either the same rosebushes you had before or try something new.
