  • Black fly

    Hi all
    I have read on a few threads that broad beans sown in winter are less likley to be attacked by black fly..
    Is this true & if so does anybody know why??
    Cheers

      It's because they are sap suckers ... and there is less sap in older, tougher plants. Young fresh green growth is full of sap, and therefore more available to aphids

          However, I have to say that when the new growth starts on the over-wintered broadies in spring - they still get the black fly. Mine did anyway.

            Yep, blackfly always attack the young new shoots at the top......that's why it's recommended to nip these off!
