    Hi all, I have started growing lupins for the first time this year and so far so good, got my first 2 flowers. My question is how do I look after them now on.... what type of food do they like ...when do I cut the flowers off to stop them seeding and where do I cut them ?? ...also what do I do with them over winter.

     Kind regards

    Lupins pretty much look after themselves.  Mine are in the ground, the borders are mulched in autumn and is about the only feed they get.  Once the flower spikes have flowered, cut them off to the base of the flower and then the smaller ones will come into flower.  

    One thing to look out for is the Lupin aphid, the big fat things have literally swamped one of my Lupins while it was in flower and made the spikes droop over.  There were too many aphids on it for the plant to recover so I've had to cut all the flowering stems off.

    Yes, when the large flower has finished flowering, cut it towards the base of the stem to just above where new leaves are forming (there should also be  a new flower shoot there too).

    I didn't realise your lupins were in pots Phil, so a general plant feed will suffice.

    No need to cut them down completely in the winter, they will die back naturally and when new growth begins next year, the old brown stuff can be pulled off.

    Sow both lots of seeds now Potting Gnome.  The night scented stock will grow and flower this year, the lupins will grow now and can be planted out but won't actually flower until next year.

     This year's leaves will naturally die back and new ones will grow for next year.

     I've never done very well with lupins - I'm wonderingif they prefer acid soil?

     It sounds like you've had an attack of the Lupin aphid Big Phil, that happens to a lot of mine here and they really do suck the sap out of the plants and make them wilt badly.  I have tried spraying with soapy water when there's only a few aphids on the plants which keeps it at bay for a while but when they are really infested, I have had to cut the plants back and most do come back again the next year.
