@WAMS I try not to spray, I find a good feed helps even my worst avoid it though, Brother Cadfael can be bad but I think i was underfeedinģ a good heap of empathy twice a year and mulch its been wayyy better ever since. This years been horrendous for spot in the garden and Albertines been hit, so have had to use a fungicide briefly to try and get it back under control as I have so many.
Worst; Zephrine Droughin - gets EVERYTHING, Purple Tiger - Zephrine wannabe, Sheilas perfume - black spot, but totally worth it. Powdery mildew; Albertine and wedding day both get BUT I realised that was airflow related and created a breeze through, really helped the problem.
Healthyrose wise, Sweet Syrie flat dosent get anything!!! Glossy and healthy, even though the roses next to it have spot.
Brother Cadfael Sweet Syrie Lost labelled HT from a show but scented, tall, not hugely thorny... littlehint of white in both blooms currently @Marlorena any ideas? Macmillain nurse
@agnasia can’t recall whether anyone said, but yes cut those dead ends of canes right down to soil level or a bit below. I occasionally have a new basal pop up in the exact same spot, but that could just be coincidence.
@WAMS I have a theory that roses get addicted to sprays and are less able to fend for themselves. I don’t spray nor judge either.
When I first planted lots of roses here BS was endemic and pretty much on every rose at some point with the exception of Astronomia. Even Julia Child got it very badly in summer. I feed and water well, practice good ‘rose hygiene’ and re-mulch at least once in the summer. Over the years incidence of BS has definitely reduced. Sometimes the weather just kicks in and this year it’s fairly bad on a few roses that have never had it before. Some DAs used to be my worst, Darcy Bussell is very prone to it whatever, but they have all got cleaner over the years. Changing weather patterns, good practices, maturity, luck? Take your pick!
Mountainous Northern Catalunya, Spain. Hot summers, cold winters.
...like a winter's day today, and has been so for some time and no change in prospect here.. I've not had the warm temps some of you have experienced.. at this rate some roses won't be in full bloom until late June !..
..meanwhile.. 'Tottering by Gently'.. 'Tall Story'.. 'Wilhelm'.. 'Sally Holmes'.. 'Sophie's Perpetual'.. ..thank goodness I have 'Marie Nabonnand' to save the day..
I need to do a separate post for 'Zephirine Drouhin'.. extollling its virtues..
@JessicaS ..sorry I can't help with that i.d. pretty HT, nice to get one with few thorns..
ok.. 'Zephirine Drouhin' is much maligned I notice.. as much as I admire Chris Warner and his roses, I'll disagree on this one.. I had this rose for some 6 or 7 years and it was never much of a problem disease wise, some bs and mildew in August, but I've had roses much worse from the outset.. the disease problems associated with it I regard as much overstated.. but that's my experience in East Anglia.. I should add, it may be worse in wetter, western parts..
I now have 'Kathleen Harrop', which is the same rose in a lighter colour.. my rose is young but as you can see, not exactly a disease magnet so far,... even last year during hot summer, I did not notice anything detrimental when even smaller.. it's not quite as vigorous as its more famous sister..
I know some of us spray, and some don't (no judgment here!), but for those of us who don't, which roses should you avoid purchasing because their disease resistance is so low they'll probably never really flourish without benefit of poisons? I asked this in another rose group and the answer was "Don't plant Austins!" but some of the healthiest and BS-free roses for me this year are DAs- Eustacia, William and Catherine, Tranquillity.
I don’t have a lot of roses (and I don’t spray) but my few DAs are completely healthy: Olivia Rose Austin, Roald Dahl, Vanessa Bell. Wollerton Old Hall has some mild blackspot now but it’s high up on a pergola and I leave it to its own devices.
Pheno Geno ‘Draga’, also sold as ‘Hallie’, is extremely shiny and blackspot free — just that something keeps nibbling the leaves and the vine weevil nematodes don’t seem to be working, but I’m not too bothered.
Flower Carpet is obviously disease free, but also scent free.
Apologies I realise I answered your question in the opposite way…
@Marlorena, wow on your ZD! I never knew it was related to Kathleen Harrop, which is such a pretty pink.
@JessicaS do show us Night Butterfly when it’s fully open!
@Marlorena Hi Marlorena, your Marie Nabonnand always looks stunning, is it a repeat flowerer, and do you think it would be suitable for more wetter, less warmer climes. Regarding the weather up here, it's been pleasantly warm and sunny during the day...18-22degrees...but ridiculously cold at night, well down into single figures, so it's taking until midday to warm up again. The poor roses probably don't know whether they're coming or going.
@WAMS I don't spray at all; I personally think as long as the roses flower, a bit more of BS doesn't matter. I try to pick regularly the BS leaves from my potted HTs; Masquerade, Louise Odier and Louis de Funes are the worst blackspot offenders. DAs are comparatively less BS prone - Summer Song has a few BS leaves. Munstead Wood has had mildew the past 2 seasons
Here are a few photos taken a few hours ago. Munstead Wood, Golden Celebration and Eustacia Vye. Golden Showers Arthur Bell displaying Peace-like shades of pink as the flower ages. Charlotte Macmillan Nurse Enchantress - huge flowers with a weak neck, but a heady fragrance. Palais Royal/White Eden - difficult to photograph as it flowers mostly at the top and facing my neighbour's garden. Queen of Sweden Our Beth - nice flower form, looks dainty.
Oxford. The City of Dreaming Spires.
And then my heart with pleasure fills,
And dances with the daffodils (roses). Taking a bit of liberty with Wordsworth

Arthur Bell is so late this year, but finally some colour. Also foaming at the neck!
Lady of Shalott is gloriously orange and relatively open at the moment.
Lovely collarette dahlia Night Butterfly is coming out, and the forget-me-nots still haven't gone over.🙃
Worst; Zephrine Droughin - gets EVERYTHING, Purple Tiger - Zephrine wannabe, Sheilas perfume - black spot, but totally worth it.
