How to grow Star Magnolia

Written by the GardenDecoded editorial team · Last reviewed 21 July 2026 · Written for UK gardens · How we research our guidance

Planting

Position out of frost pockets and away from an east-facing aspect — the flowers open early and frosted buds thawed quickly by morning sun turn brown. Plant shallowly and mulch rather than digging around it later.

Pruning

Prune as little as possible. If a branch must go, take it out in midsummer; magnolias heal slowly and winter cuts often die back further than you intended.

Propagation

Softwood cuttings in early summer under mist, or layering. Neither is quick, and most gardeners are better off buying a plant.

Pests and diseases

Generally healthy. Coral spot can enter through pruning wounds and dead stubs, so cut cleanly and remove dead wood.

Value to wildlife

Early flowers give some pollen to bees on the first warm days, though this is not a major wildlife plant.

Notes

Roots are fleshy, shallow and easily damaged — never cultivate beneath it, and keep it clear of a lawn edge where a strimmer or spade will reach. It is slow, adding perhaps 10–15 cm a year, which makes it one of the few magnolias that suits a small garden.
