Propagation

Seed - surface sow in a greenhouse in spring[113]. Cover the pot with paper until the seed germinates[78]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 8cm long, July/August in a frame. Overwinter in a greenhouse and plant out in late spring[78]. Thick growths make the best cuttings, but these should be placed in individual pots[78]. Good percentage[113]. Cuttings of mature wood in late autumn in a frame[200]. Mound layering in spring. Takes 12 months[78]. Division of suckers in late winter[113]. They can be planted out direct into their permanent positions. Leaf-bud cuttings of the current seasons growth in a frame[200].
