Rita hoping for the best with all of your lovely roses, they may surprise you since your spring is delayed. I sure can understand about you not wanting to dig up dead ones and replanting it takes a lot of energy, plus your pruning and spraying them must also take lots of energy. I know I couldn't keep with that many, the roses that are here are all very hardy growing on their own root systems.
I was listening to the weather today and they said we actually had nine inches of snow, no wonder it seemed like a lot. They are talking about more tomorrow night I am hoping that misses us.
