We have also had the dreaded blackfly on nasturtiums ,looked terrible, so they ended up in the composter. Just hope the little devils leave my runner beans alone !
I've never grown nasturtiums before this year and they are slathered in blackfly to the point where the plants were just just miserable...I've cut them back in the hope the black fly will run out of steam.
I don't know about the sacrificial plant Paulk2, but the black fly on mine seem to have spread to other plants.
Had to keep one plant intact as it had large white caterpillars on and now I don't know where the pupae are so I'll have to leave it in place...they are hard work for bedding plants I have to say =+\

The thing that I wonder about is would you have had the blackfly without growing the nasturtiums which seems to attract them like a magnet and/or does growing nasturtiums make it worse for all the other plants in the garden?

Is it still recommended to grow nasturtiums as a sacrificial plant for other more precious plants in a garden that would also be affected by blackfly?

I read that helps.

I wondered that also or if it is just coincidence that I have mountains of black fly the first year I have grown them
Edit: noticed a sparrow eating them this AM so not all bad
