How to prune magnolia grandiflora 'gallissonnière'

Late summer after flowering, or mid-spring once frosts have passed. Remove dead or damaged limbs back to the branch collar with a clean cut. For wall-trained specimens, cut back outward-growing shoots to 2–3 leaves after flowering. Avoid removing large limbs — magnolias compartmentalize wounds poorly.

Rarely; inspect annually and remove dead growth only as needed. Magnolia grandiflora 'Gallissonnière' needs minimal pruning. This evergreen magnolia resents hard cutting and heals wounds slowly, making it prone to disease. Limit work to removing dead, damaged, or crossing branches. Shape only if needed to clear a path or wall, and always use clean, sharp tools to minimize damage.
