Rose black spot/rust: too late to hard prune?
I've been away from the garden for over a month and have come back to my two Darcey Bussell roses absolutely covered in black spot/rust
There's lots of advice on the internet as to how to prevent or treat this, but little advice as to what to do if you're at the stage where the roses are in too bad a state to treat (which I think is the case here). Every single leaf I can see is affected... So what now...? Can I give them a hard prune at this stage to remove this year's leaves / growth and start again or is that too late at this point in the year? They were so beautiful and healthy throughout last year's hot summer too... the
