Prick seedlings out into individual pots when large enough to handle, then grow on in light shade in a cold frame or greenhouse for at least the first winter before planting out in late spring or early summer. Other options include half-ripe wood cuttings in July/August in a frame, ripe wood cuttings of the current season's growth at 15–30cm long in a cold frame, root cuttings in late winter, or division of suckers during the dormant season.
