Campanula Blue Belle, divide or not?
Last week got a good deal on 3 for 2 perennials, ( 3 litre size) at a local independent nursery in Glocs. A new geum called Sunrise and a Geranium ( a colour we haven't got), they will go in back garden , but want to split the campanula into maybe 6 plants . Is it a good idea to do it now ? Or wait it's still mild here in South Wales.
