How to grow

Cultivation Easy to grow in most moist soils and will tolerate hard pruning. Not susceptible to aphid infestation and is therefore free of sticky honeydew. Avoid exposure to cold drying winds

Propagation Propagation is not easy but to propagate by seed, sow stratified in containers outdoors in spring. Chip budding is the most appropriate method although care must be taken with the choice of rootstock
