Dig up the root clump and cut off as many sections as you require, making sure they all have at least one growing point. The larger of these divisions can be planted out straight into their permanent positions, though small ones are best potted up and grown on in a cold frame until they are established.Root cuttings, 3 - 10 cm long, in spring. These can be planted straight into the open ground or you can pot them up in the greenhouse and plant them out once they are growing strongly.
