Take heel cuttings, 3-4 inches long from half-ripe lateral shoots preferably with a heel at any time between early and late summer. Insert into equal parts of sand and peat in a propagating case at a temperature of 16C. When rooted, pot the cuttings singly in 3 inch pots of John Innes No 1 and overwinter in a cold frame. The following spring, pot on into 4 inch pots and plunge outdoors until planting out in autumn.
