Blackspot infestation on Peace Rose - any solutions / advice?.
I have a much loved Peace Rose (which I've had for 11 years) which, while always susceptible to the odd bit, now seem to be under attack from blackspot. Pretty much every leaf is affected. Is there anything I can do to get rid of it (I don't want to use sprays if I can help it as I don't want to harm any insects)? I've been picking off the affected leaves and throwing them in the bin but it's just getting worse and the poor thing will have no leaves left if I keep going. Is it just unsightly or do I need to get rid of it. I'd hate to lose the rose. Wasn't sure if a good hard prune would help.
