I have a yellow rose for about 25 to 30years which has produced lots of beautiful scented flowers every year. This year it did flower but not quite as much but now one large branch with leaves have turned a copper colour very quickly and the rest of it seems to be starting to go the same way. Could it be dying off altogether. I would hate to lose this plant. Is there a successful way of taking a cutting from it if it cannot be saved.
It may not have flowered so well due to dull weather, but it is possible that it may have a root disease.
Take some cuttings now, either indoor ad covered with a plastic bag or outdoors as it is a good time now to root rose cuttings outdoors.
