Not a clue -- but if we knew where you were located, we might eliminate some possible causes.

Thanks Jim! I didn't realize the pic was sideways! It looked right side up on my iPhone! I am in southern Ca... Zone 9 ( or 19 sunset) ... I'm in a coastal valley.. Fairly dry and moderate. We received very little rain this year and no frost. I'm worried about nematodes.., there were some in my veggie garden that killed my tomatoe plants last year.

Thanks for more info... I'll let those that live in California have the floor as they are much wiser than I whom lives 3000 + miles away...lol

Sabine, I live in a hot, dry area in San Diego County and have noticed that, with the little rain we've had, many of my roses are suffering, in spite of watering every second day. The other day I dug down into the dirt around some of the roses and discovered that, although the top was moist, one or two inches down there was no moisture at all. What I'm doing now is putting the hose to each plant with just a trickle of water coming out and leaving it there until I can see that there's moisture further down when I check with a trowel. Have a look at the soil around your roses; you might be having the same problem. Other than that I can't imagine what could be causing the dieoff. If it is a lack of water I would also put mulch around the roses, if you haven't done so already, to keep the sun from sucking up all the moisture.

Thanks Ingrid,
This rose is so old and established I never really had an issue with water, I just recently started to let the area soak. The part that concerns me is that it is the only rose in my garden that is behaving this way. I think I am going to take soil and tissue samples in to get tested
