I have a recently purchased a standing rose in a pot which up until a few days was ladden with buds, then suddenly it began to shed all of the buds leaving black stalks in their place. The various potted plants that we're near the rose also appear to be withering.

It has been suggested to me that there was some form of virus and I should take the rose back to garden centre.

Any thoughts/suggestions would be much appreciated.

In anticipation

Dan
