I have a few you young plants in 2 litre pots. When should I take cuttings? Autumn,whilst it is warm or when it's dormant(if we have a winter this year!)?
if they are young plants, I would wait till Autumn to give them a chance to beef up a bit. I planted some years ago and found they sulked for a good year, then settled in rather too well in places! I have just pulled some up to stop them taking over a border and stuck them in pots for a friend who wants some, but am not expecting a massive success rate.
Gosh Cotty, I've been so unnerved by posters sightings of Japanese K that I was aghast to read that you actually want to take cuttings.....I had to re-read your title and still find myself doing a double take when I come across it.

I've always done root cuttings as plants go dormant for winter.
My success rate isn't that great though
In the sticks near Peterborough
Would you pot it up or put it straight into the garden, mine is about a foot tall now?
Traditionally root cuttings are done in late autumn.

Don't worry lavande(r) it isn't knotweed I am interested in.
I think I will take your advice gingly,let them get bigger with more established roots and whilst it's warm take some cuttings.
I have done this in winter with sea holly and acanthus with limited success. The warmth might help?
I will try that link later Dave when the kids are in bed. Got to plant some asters that I pinched from the in-laws before they dry out
