Is this black spot? If so, what should I do?

[BlusyTusday]

My newish and usually healthy rose isn’t looking too happy at the moment. I was wondering if this was black spot, or just what a rose might look like in a pretty mild and wet January? If it’s the dreaded black spot what should I do? TIA

Your options are:

Conduct an all consuming campaign against it from now until the end of time

Or just give up, feed and prune your roses as normal and accept that it's there.

After many years of option 1, I now do option 2 and enjoy the garden and the roses a lot more as a result.

Cut all diseased leaves off now, and also collect all fallen ones from under the bush. Then prune as normal by Valentine's Day, and keep an eye out for any sign of it on new leaves. You can always spray with a rose fungicide if it reappears on new growth, but some varieties of rose are more susceptible to it than others, so it might return on a regular basis.

Forgot to mention, don't compost diseased foliage, throw it in the bin.

I agree with @AnnaMagnani. IME it's not worth worrying too much about. In my garden it only really affects one particular rose, and I don't like the idea of spraying around a load of chemicals just for that, although you can spray the new shoots as they appear. It can be a sign of neglect, so feed well through the season.

Keep on top of diseased leaves as soon as they appear and dispose of them, including any fallen leaves. As PPs say, do not put them on your compost heap!

Can’t see any black spots on the healthy leaves, so I don’t think it’s blackspot.

Black spot spores are everywhere, so don’t get too hung up with destroying every leaf.

even if the bush is completely defoliated, they seem to come back happily next year.
