do i prune or pull out lupins and hollyhocks ?

I dont know about hollyhocks, but I just cut lupins right back when they look tatty. Mine are still flowering, so wont be for a while yet.

I am not really in the know but for the last three years the hollyhocks in the garden I took over have just ben dead headed and the bad leaves taken off them in autumn. BY deadheading I mean I just tcut the flower stalk right off. This worls for me as they have re-flower but knowing me its probably more luck than judgement.

Sorry, i also meant to say that lupins will come back year after year - so dont pull them out unless you dont want them anymore.

But remember lupins are short-lived perennials...best replaced every few years. Hollyhocks are perennials but treated as biennials....they tend to get an unsightly rust...again...replace every few years....
