Magnolia trees need consistently moist, slightly acidic, well-drained soil. They should be watered regularly until they're established, with greater frequency in warmer weather. While deciduous varieties prefer full sun to part shade and situated where sheltered from wind, evergreen varieties thrive in full sun and only need protection if planted in areas prone to frost. 

 

All magnolias can be pruned/trained to your desired size. Be sure to prune after flowering or in late summer.
