The best time to take them is in early autumn.
Select sturdy shoots from the current season growth, and cut them into 200-250mm (8”-10”) lengths, remove all the lower buds
to leave four at the top.
Form a groove in a sheltered bed, fill it with sharp sand and insert the cuttings, to half their length 150mm (6”) apart.
The cuttings may take up to 12 months to root.
When rooted, they can then be lifted and planted out into their permanent positions.
