| I looked online, and saw similar canes where the site said it was blackspot. I've never before noticed a rose where the canes had blackspot, and the foliage was fine.

| I'm not an expert, but it looks like canker....although black spot can present on the canes as well. Tammy |

| Looks like canker to me too, Jill. Jackie |

| At this time of year I'd have to agree with canker. I have seen blackspot present like that coming out of winter in the very early spring but not that I know of mid-season. If it were blackspot at this time of year it would show all over those leaves already. |

| Thanks for the responses. OK, so what should be done about it? I can't spray for it. Should I remove the affected parts and see if there is any plant left? Should I just try to find another of the rose (Country Living)? Are some roses more suseptible to canker than others? TIA Jill |

| Hi Jill, i am in agreement with everyone else,..i would surely say it is Canker,..which is a Fungal Disease,..there are a few species of Canker plus a similar one called "Black Saddle",..yours appears to be brown from your picture. What to do,..well i would cut off most of the diseased canes and burn them,..do not leave them in the garden seeing its a fungal disease,.then i would douse the remainder of the canes with an Anti Fungal Spray,..i make up my own sprays but you can Google for "Anti Fungal Home Made Mix/Spray",..if you want you can purchase a spray,..the same spray against "Black Spot",..will do. I would certainly try to save the rose bush,..and it can be saved and taken back to full health. |

| Jill, I had (I think) about 5 this spring that had canker pretty badly. I cut back the canes as far as I could, and 3 of them survived, while 2 did not (well, one of the two is sort of hanging on but I think its getting shovel pruned shortly...) As for Country Living, when I purchased it this spring, I think that Hortico was the only nursery offering it. Of course, there's mixed opinions about them, but I placed my first order from them for this past spring and everything went fine. Tammy |
