These trees are known for their large, glossy leaves and fragrant, showy flowers, making them a popular choice for home gardens, commercial areas, and parks.

Propagation:

Southern magnolia trees are relatively easy to propagate. They can be grown from seed, but for more predictable results, consider propagating from cuttings. By following simple steps, you can create exact clones of the parent plant, ensuring consistency in size, shape, and growth rate.

From Cuttings:

• Take an eight-inch cutting from the tree in the spring.
• Remove excess leaves, leaving only the top two, and vertically cut them in half to reduce tissue.
• Dip the cutting in rooting hormone and plant it in a container with seed starting medium.
• Keep the soil moist and place the pot in a partially sunny area until roots develop.
• Transplant the cutting into the ground once it has established roots.

Growing Tips:

• Southern magnolias thrive in full sun to partial shade.
• Maintain even moisture, especially for young trees, and provide adequate drainage.
• Apply mulch around the base to retain moisture and reduce weed competition.

Pruning and Maintenance:

• Prune lower branches that obstruct walkways or touch the ground.
• Remove branches with tight crotches to prevent breakage.
• Prune in late winter or early spring to avoid frozen wood.

Recommended Cultivars to Select:

• ‘Bracken’s Brown Beauty’
• ‘D.D. Blanchard’
• ‘Edith Bogue’
• ‘Goliath’
• ‘Kay Parris’
• ‘Green Giant’

Each cultivar offers unique features, such as different flower sizes, foliage colors, and growth habits, allowing you to select the perfect magnolia tree for your garden.
