Answer: I sure wish I could inspect the plant! That would make diagnosis the problem much easier! If the stems or branches are dying one by one I would suspect a root or a crown rot, or damage from borers. You'll need to put on your detective cap to determine which it might be. Cane borers leave holes and little sawdust looking particles wherever they bore into the canes so carefully inspect all of the canes for this type of damage. Crown rot is more difficult to see. You'll need to brush away the soil from the tops of the roots to look for mushy or off colored stems. Likewise with root rot. You'll need to dig down and inspect the roots. I hope you find the problem before you lose your entire rose bush!
