Thanks for your reply water butts posted previous before reading yours.
I was hoping I could avoid this. But I know you are right!
I have just cut the geranium back to ground level as they had finished flowering/looked tired from dry weather. I don't know weather they will have second flush of flowers? So was thinking of doing it now, but I never give it a thought to leave it till the autumn.
I will lose all the geranium though as it would be impossile to do. Don't fancy the fine tooth comb option
