Not normally grown from seed as it is unlikely to be true to the parent plant. Hard wood cuttings can be taken in autumn, or buds grafted to rootstock
Take 30 to 40 cm hard wood cuttings and strip off all but the top two leaves. Dip into rooting hormone and insert into a trench with added grit prepared in less sunny part of the garden. The cuttings will be ready for individual planting the following autumn
Normally grown from bare root stock, commercially produced, that are best planted out in early winter while the plant is still dormant. Dig a hole in a sunny spot deepen ought to take the root and covert graft by 4cm. Back fill, and add some blood, fish and bone, water well, heel in, and cover again until the graft is covered by 4cm
