Propagation Notes:
Seed - best sown in a greenhouse as soon as it is ripe in the autumn. Stored seed may requires up to 3 months cold stratification, though scaritication may also help[113]. Sow stored seed in a cold frame as early in the year as possible. Germination should take place in late spring, though it might take another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant them out in early summer.
Cuttings of half-ripe wood, July/August in a frame.
Root cuttings, 3cm long, planted horizontally in pots in a greenhouse. Good percentage[78].
Suckers, removed in late winter and planted into their permanent positions[113].
