Best sown as soon as it is ripe in a cold frame, it usually germinates in the following spring. When large enough to handle, prick the seedlings out into individual pots. Protect in the green house for the first few years before planting or potting them outdoors.
Cuttings of young shoots in June or July. The cuttings should have 2 - 3 pairs of leaves, plus one pair of buds at the base. Remove a very thin slice of bark at the base of the cutting, rooting is improved if a rooting hormone is used. The cuttings need a humid atmosphere as they can wilt and quickly die in dry conditions. The rooted cuttings must show new growth during the summer before being potted up otherwise they are unlikely to survive the winter.
Air-layers should be carried out in May. It takes about 12 months, if successful.
