Care notes

Cultivation
For fruit production, grow as a goblet-shaped bush. Keep clear soil in a 60cm radius around trunk
Pruning
Brutting or breaking sideshoots half way along their length in August followed by shortening the brutted shoots to 3-4 buds when the catkins are shedding pollen in late winter. When necessary remove up to one third of old overcrowded shoots to the main branches
Propagation
Propagate by chip budding in mid- to late summer or grafting onto clonally produced rootstocks or seedlings in late winter.
Pest resistance
May be susceptible to caterpillars, gall mites, aphids and sawflies. Squirrels like to feed on the nuts
Disease resistance
May be susceptible to honey fungus, silver leaf and powdery mildews
