Information on Planting Magnolia Trees

Magnolias grow best with access to full sun conditions.

Magnolia trees are some of the most iconic trees available in the southern United States. These trees, known for glossy green leaves and creamy white blossoms, are fairly easy to care for once the trees acclimate. However, due to an unusual root system, planting and transplanting Magnolias can be difficult.

Planting Zones

The first step to growing a healthy magnolia tree is growing the tree in the proper climate. Southern magnolia trees grow best in planting zones 6 through 10.

Soil Conditions

For a young magnolia to thrive, the proper soil is essential. Magnolias respond best when planted in rich, well-drained soil. Soil pH should range from neutral to slightly acidic, suggests the "Southern Living" website. Mix compost or other organic material into the soil.

Space

Ensure the magnolia has plenty of space to grow, as mature magnolias are very large. Southern magnolias reach a mature height between 60 and 80 ft., with a spread reaching 40 ft. Small, shrub-like varieties of magnolias are also available.

When to Plant

Southern magnolias and other evergreen magnolias should be planted in the early spring. Deciduous types can be planted in the fall or the spring, according to the United States National Arboretum.

Planting and Transplanting

Dig a hole 2 to 3 times wider than the root ball of the tree. The hole should be about as deep as the root ball, as most roots grow in the top foot of the soil. Transplanting magnolias is not recommended, except for very young trees. Cut off the roots the year before transplanting will occur. Dig a hole as wide as possible, to ensure most of the roots are captured.

Light

Magnolias grow best when planted in full sun, so choose an area of the garden that receives six to eight hours of light daily.
