I have a rose 'blue rhapsody' which I bought in the summer from a local rose society. It's had 4 lovely flowers this summer, though they were suspiciously less blue than the plants displayed at the show!
It's finished flowering now, and has picked up blackspot. I was just wondering, when I should prune it and if I need to treat it with fungicide now or wait until next spring?
