How to prune acer rubrum 'autumn blaze'

Late summer (July–August) or late autumn after leaves drop. Make clean cuts back to the branch collar — never flush cuts or stubs. In the first 2–3 years, select a central leader and 4–6 well-spaced scaffold branches, removing any competing upright stems or included bark unions. On mature trees, prune reactively only when defects are found.

Rarely; formative work in years 1–3, then only as needed. Acer rubrum 'Autumn Blaze' (a red × silver maple hybrid) has a naturally upright, oval habit that needs little corrective pruning. As with all maples, avoid late-winter and early-spring pruning to prevent heavy sap bleeding. Remove dead, damaged, or crossing branches in summer or late autumn. This cultivar rarely needs crown shaping once established.
