Thanks for this Bekkie (and nutcutlet - yes I should have given the alternative same, well done). That sounds about right; I'll set to dead-heading, which is never a bad plan anyway.
As a matter of interest, what sort of location are yours in Bekkie (eg: are yours in full sun in Devon or facing North in Aberdeen etc) and how tall etc have they got in how many years? (and is all this information free? I should be so lucky ... )
