Seeds:

Grafted Magnolia grandiflora plants can be purchased from nurseries. Propagation can also be accomplished by taking cuttings from existing plants and grafting them onto a new rootstock. Magnolia grandiflora is compatible with a variety of other Magnolia species, so it is best to do a bit of research prior to grafting to determine which species will provide the best graft.

Layering is an easy way to propagate Magnolia grandiflora. Find a healthy mature branch on the plant and scrape away the bark at the base of the branch. Bury the bare area in soil and cover with a layer of mulch or compost. The branch should take root in approximately 6-12 months, at which point it can be cut away from the parent plant and transplanted to a new location. Make sure the new soil has the same acidic properties as the original soil.
