How to prune filbert 'barcelona'

Late winter to early spring, after catkin pollen shed (late February–March). Remove 1–3 of the oldest, thickest stems at ground level each year. Open the centre by cutting any shoots growing inward or crossing. Remove all suckers by tracing to their origin and cutting flush. On trained trees, shorten side-shoots to 5–6 leaves in summer to expose developing nuts.
