Hi - I have got several lupins in my garden, which have had a terrible year presumably because of the lack of sun. For the last 6 to 8 weeks, they have been absolutely smothered in green/whitefly - often two or three deep. I have gone around many times wiping them all off with kitchen towel (and squashing a lot of them!), but the next day, there they all are again. I have also sprayed with organic pesticide - I think that it is fish oils - which washes them all of, but again, there they are again the next day. I bought a load of ladybirds, which all promptly flew away (home I guess ), and now my lupins are all dead looking, with grey/black foliage and very floppy. Any greens bits are still smothered with greenfly. Do you think that they will come back again next year, or have the flies sucked all of the nutrients out of them? If they are doomed, I might take them out now and put new ones in next Spring. Thanks as ever for all your helpful advice!
