Provide Jane Magnolia with well-drained, slightly acidic soil and ensure it receives full sun to partial shade for optimal growth. Water regularly during dry spells, especially when the plant is young, to maintain consistent soil moisture. Prune after flowering to shape the tree and remove any dead or crossing branches. Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth and abundant blooms. Protect from strong winds to prevent damage to the delicate flowers.
