We actually just got this house about 2 years ago so I have no idea what type of rose it is or how old unfortunately....but thank you all for the info I figured the other plants had something to do with it. I'll see what I can do about it later today.
We got a drench for that, but when the stuff melted the surface of a plastic measuring spoon, we gave up that idea. Instead, we did what local avocado growers do for avocado root rot (a closely related fungus). We got FRESH horse manure from a stable. Piled it around the base of the plant, from a few inches away from the base all the way to the drip line. That did the job.
I agree that the plants all around it need to be cleared away, and I would feed the rose. And you need to cut off all of the dead canes. (Dead stuff isn't helpful.)
I would also ask what rose this is?
How old is the plant?
What did the blooms look like LAST year?
What did the blooms look like THIS year?
