Start with telling us where in the world you are.

In an area of high blackspot pressure, I found Dublin Bay very prone to the disease. It is long gone. If this happens every year, either start spraying with a fungicide, or pull it and replace with something more disease resistant like Quadra.

Sorry located in zone 7 Central New Jersey i got this from Heirloom roses and asked them for something that was low maintennace ( as low maint as roses can be)

Get rid of it. Ask here for local recommendations for roses that will be blackspot resistant in an area with extemely high blackspot pressure. Pay no attention to people who are either west of the Appalachians, or people who don't give a location.

May I recommend the Kordes rose Florentina in its place?

I agree with @mad_gallica (z5 Eastern NY). A west coast nursery isn't necessarily going to know which roses are going to do well in an eastern location. Unless you start applying fungicide to your rose every 7-10 days, you're going to have a leafless pile of sticks every year. It's shown you what it's like in your climate, so there's no reason to think it will suddenly improve in performance. Bid it farewell and don't look back.

'Bantry Bay' is bred from 'Altissimo', and in my experience, pretty much all offspring from 'Altissimo' have serious issues with Blackspot. Any plant of 'Altissimo' I ever saw was leafless 90% of the growing season.

I suggest looking at some of the Canadian Explorer roses, such as 'Quadra', as was recommended.

Thanks for the feedback when it bloomed in the spring it was amazing but then it became high maintance i will take your advice and check out the suggestions any other suggestions for New Jersey rose vines that are low maintenance are appreciated

I'm in zone 6 central NJ, and grow hundreds of roses. I don't spray at all, and yes, I get blackspot. But I've learned which roses can shrug it off and survive (lots) and which simply are too weakened by it to survive the winter (most hybrid teas, some older floribundas, etc.) My question for you is - do you expect perfection of foliage from leaf break to frost, or is "pretty good" good enough? If the former, then honestly, I think here in humid NJ you are going to have spray - or grow something else (maybe a gold flame honeysuickle?) If good enough will work, well, there's lots of options. I just had a walk through my garden, and these climbers - Parade, John Cabot, Capt. Samuel Holland, Honeymoon Arberose, Sir Paul Smith (probably hard to find), Red Dawn (also hard to find) Climbing Pinkie, and Cape Diamond were among those looking pretty good, to me. A few yellow and spotted leaves, but not badly defoliated and most of the leaves green. I don't grow a lot of reds, if that's what you are after, but I thought Don Juan didn't look bad, etiher. I guess my philosophy is this: I want my roses to be glorious for their big spring flush in May and June. And then, hot humid weather comes in July, and they're not going to look their best. But I don't expect them to be perfect (I'm certainly not at my best in 90 degree weather with a dew point of 72, which we had last week and will again by the end of this week). So again, if you expect perfect foliage all season and no spraying, roses may not be the best choice. A suggestion: are you anywhere close to Somerset County? (I'm assuming so if you are in central NJ). There a place called Colonial Park where they have a big rose garden: https://www.somersetcountyparks.org/colonial-park-gardens/pages/rudolf-w-van-der-goot-rose-garden. They have lots of roses AND the rosarian there is this guy named Christopher who used to post here all the time but no longer does. Anyway, he's really nice and VERY knowledgable about roses. I don't know if they spray there, but if so I'm sure he'd give you an honest report of how often, etc. And also of which roses do best for him. Checking out BBG and NYBG is also an option (NYC is about an hour away from me on NJ transit). The climate there is very similar to central NJ. Though I have no idea if they spray or not (I'd guess they do, but ...?) Anyway, best of luck! I hope you find either a rose that will do for you, or some other climber that will make you happy!

I think you have gotten very good honest advice regarding the situation with your rose. I will like to say that here also in the south east Florentina does great no spray. It keeps all foliage intact until late in the season when there are some infected leaves by cercospora or something similar. She is my only blackspot resistant red climbing rose.

@Frances White Thanks for the great detail. The Honeymoon Arberose looks really interesting. Will give it a shot.

Third vote for Florentine and Raspberry Cream Twirl if you like stripes and thornless!😉
