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've just had a couple of stems with small clusters. I tend to use a
domestic Pyrethroid fly spray to spot treat these, not worth mixing
for 2 or 3 stems.
Sacha, your dahlia is now in bud.

Could you take a pic and let us see how it turns out, David? Is it outside
or in a greenhouse? Your D. excelsa is looking wonderful, apart from the
blackfly. I've put seed feeders near it in the hope the birds will take the
hint and the blackfly!
