I regularly grow purple surfinias; this year they have Developed white spots on the flowers which then fade to a very light lilac instead of the intense blue/purple that is usual. Does anyone know what the problem is or how to control. I am of course deadheading.

« Hi Everyone, I have two questions. I work near St Pauls Cathedral (in London)...
Have the white spots only been a problem since the weather got very hot?
