My broadies are covered in blackfly can anyone recommend an organic solution? I do have lots of ladybirds but they are having very little impact.
Nip the tops off. Squish the little barstewards. Spray with Perithrin - in the evening after the bees and ladybirds have gone to bed.
Nip the tops off or spray with soft soap. If the broadies are near to trees or hedges, a strategically sited feeder might bring the blue tits in, though they seem to like greenfly more than blackfly. Personally I leave them alone as I'm far from convinced that they do any real harm.
Black fly and broad beans are the marriage made in hell.
Nearly always happens.
I found that you do need to spray even after nipping the tops off, if you do not catch the blighters soon enough, so check daily for them, they are sure to arrive.
Thanks for the advice I shall pop up this evening and pinch out the tips.
Sad to say, pinching out the tops has never stopped the black fly once they are on the plants, well they never have on my plants.
