Does anyone know what this illness is? Roses

[Fiona1987]

Hi everyone,

one of our roses is dying. Please find picture attached.

We have no idea what the illness is. Any advice?

Thanks xx

Can you take a close up picture of the leaves, both sides of the leaf and and both yellow and green leaves? It looks like it might have black spot but it's hard to tell from the photo.

Black spot. Only way to fix it is to just chop every infect area. It'll infect all the other roses bushes in the area

I'm not entirely sure that's black spot, the affected leaves don't have a typical black spot appearance. You would expect to see leaves developing a dark spot in the middle. Most my roses seem to get black spot, it's a nuisance but it's rarely fatal. It's a fungal disease which can be treated with sprays like Roseclear, which should help strengthen your rose.

There's a lot of research into breeding new rose varieties with strong fungal disease resistance, but unfortunately fungal diseases and viruses are continually mutating, so roses which were disease resistant initially become less so as the contagion changes.

Your best bet is to get your roses in the best health you can, so plenty of feeding and watering. I spray mine with Roseclear at the first sign of trouble and cut off any badly affected shoots (put these in the landfill bin, not compost or garden waste bin) and simply hope for the best.

Some of the symptoms your rose has indicate deficiencies, so I would give it frequent feeds (as well as the fungicide spray) and see if it picks up.

My guess is a combination of drought, sun scorch, wind damage and some sort of mineral deficiency.

How long have you had it, and what is it planted in?

@yamadori: we've had it for about 2 months and it's planted in some sort of rose compost ( my partner planted it, but he can't really remember what he planted it in). We planted about 8 roses in our garden, the other ones are doing fine

@TheNoodlesIncident: Thank you for your advice. We'll remove this rose tomorrow to protect the other roses, but we'll get a bottle of roseclear for the future.

You don't need to get rid of it yet, @yamadori could be right and it's simply a combination of damage by the elements. I had one plant get a whole barrage of black spots on the leaves. The blackened areas died and went brown, but subsequent new leaves were fine and I suspect the cause was an animal, probably a tom cat or fox, spraying the new plant with pee. It was unsightly but the plant wasn't harmed very much.

If you feed your rose and keep an eye on it for a couple of weeks, you should see new growth which looks healthy. If not then chuck it out, but there's no reason to give up on it yet - and roses are notoriously greedy hungry and need feeding pretty much continuously over the growing season.
