Most years black spot hasn't been too much of a problem (I've only got one rose - a climber) and I've just picked off the affected leaves when I've spotted them.
This year I wouldn't have any leaves left if I did that and despite the black spot it's the best display of roses I've ever had.
I'll have to resort to spraying, but I'm a bit concerned about spraying so many open blooms. Anyone know if that's a problem?
