Have two very nice ones from Sacha's and have taken cuttings but is it
possible to get the actual plants through the winter in say an unheated

Should I cut them back or just chnace taking cuttings ?

Janet, they very easily overwintered in frost-free conditions and
cool, dry, bright and airy are the keys to success. Cut the main
stems back by about a third (more if you have problems with space),
remove old, diseased and yellowing leaves, place in good light and
water only when dry. During winter they don't need anything special at
the root so old potting compost is fine as long as it is gritty and
free draining. The plan is not to keep them growing - winter light in
the UK is too poor for healthy growth, just gently ticking over.
Argyranthemums suffer far more from cool, dank conditions than they
ever do if it is cold and dry. Good ventilation will keep them in
good health and as long as temperatures don't fall below approx. -3C
for long periods, they should be fine.
