How to prune english walnut 'pedro'

Late summer to early autumn after harvest. Young trees: train a central leader with lateral scaffolds spaced 60 cm apart. Mature trees: remove dead, diseased, or crossing limbs outside the branch collar; cut water sprouts flush. Minimise wound size — walnuts are slow to compartmentalise large cuts. No heavy thinning once established.

Annually for light maintenance; structural training in years 1–5. English Walnut 'Pedro' is a late-leafing, partially self-fertile cultivar. Pruning approach is the same as for 'Hartley': establish a strong scaffold when young, then transition to light annual maintenance on mature trees. Avoid pruning in winter or spring when sap flow is high — late summer after harvest is ideal.
