Redtop19 - I don't know what type of rose you have, but it doesn't seem to affect single roses quite as much.

Monty Don mentioned this on Gardeners World a few weeks back, his solution was to just snip off the whole head before flowering as it obviously wouldn't amount to much. However some people peel off the outer petals in order (or an attempt) for the rose the bloom, although I guess you would have to do this before things got too bad.

Wet weather and no sunshine are ideal conditions for this, as they reckon roses need a good spell of dry weather. Also, avoid over-watering, spraying/misting those that are susceptible.
