Magnolia Care Guide: Planting, Watering, and Common Issues

Site Selection and Soil Preparation

Magnolias are fast-growing trees that thrive in full sun across Georgia, yet they tolerate heavy shade better than most evergreens. For maximum growth, prepare a planting hole approximately 4 feet wide and 2 feet deep. Firm the soil beneath the root ball to prevent future settling.

Planting Depth and Initial Watering

Plant the tree at the same depth it grew in the nursery. For balled-and-burlapped specimens, the top of the burlap should remain visible after planting. Water thoroughly to settle soil around the roots.

Managing Transplant Shock

Magnolias often show transplant shock during the first growing season. Older leaves may yellow or brown and drop, but as long as terminal leaves remain and new growth appears, the tree should recover and resume normal growth the following year. Water young trees weekly during dry periods in spring, summer, and fall, and apply mulch to retain soil moisture.

Pruning for Strong Structure

Single-trunk magnolias are more attractive than multi-trunk forms. When the plant is small, prune out side branches that compete with the central leader. All magnolias eventually flower, though seedling variations mean some bloom earlier than others.

Common Pest: Magnolia Mites

A frequent problem on Southern magnolias is a microscopic mite that feeds on leaf undersides, causing brown discoloration near the base and margins. The corresponding upper surface turns yellow, and heavy infestations can cause premature leaf drop.
