How to prune magnolia 'susan'

Immediately after flowering in mid to late spring. Cut out dead and crossing branches back to a healthy lateral or main stem with sharp, clean tools. Remove any suckers from the base by pulling rather than cutting to discourage regrowth.

As needed; minimal intervention preferred — once every few years is typical. Magnolia 'Susan' is a compact deciduous magnolia that needs very little pruning. Remove dead, damaged, or crossing stems immediately after its purple-red flowers fade in spring. Lightly shape to maintain an open, balanced crown at the same time. Avoid pruning in winter or autumn — magnolias are prone to bleeding sap and fungal entry through winter wounds.
