My dahlias are smothered in black fly too.

Our Dahlia excelsa (present from David Hill) has had a real blackfly
attack.
I was walking past it this afternoon and saw twisted and 'sad' leaves
and
then, further up this very tall Dahlia, several stems and leaves
infested
with the critters. I don't remember it suffering like this before and
as
there are loads of sparrows nesting in the eaves above it, I think the
ungrateful little devils better get to work!
Ray has sprayed it with an organic spray, so we will inspect again
tomorrow.
Is this a particularly bad year for blackfly in others' gardens?

I had some on my runner beans, but I haven't really done any more checks
to
follow it up.



They love broad beans too, don't they?
