How to Grow a Star Magnolia Tree

The star magnolia (Magnolia stellata) is one of the most popular landscape trees in the United States, and for good reason. This multi-trunked ornamental deciduous tree has spectacular white star-shaped blooms in early spring. It is an excellent specimen tree for just about any location and even works well in naturalized locations. Here's how to make this magnolia the star of your home garden.

Things You'll Need

• Star magnolia tree
• Shovel
• Knife
• Garden shears
• Water
• Mulch or other organic material

Instructions

1. Select the planting site. A location that receives full sun in the morning and some shade in the afternoon is perfect for the star magnolia. The soil should be evenly moist, slightly acidic and rich in organic material. Star magnolia will adapt to many soil types so it is worth trying in various locations. The tree can be successfully grown in Hardiness Zones 4 through 9.

2. Prepare the tree. Star magnolia is readily available either containerized or balled-and-burlapped. Remove all wire and twine used to secure the rootball. Cut away half of the burlap covering the rootball.

3. Dig the planting hole. Dig a hole three to four times the width of the rootball or container and equally as deep. When planted, the top of the magnolia rootball should be even with the surrounding ground.

4. Position and plant the tree. Place the star magnolia in the planting hole. When the tree is straight, add a small amount of soil to help secure it. Fill the planting hole with water and allow the rootball and soil to absorb. Backfill the remaining soil and water again deeply.

5. Mulch the planting area. Mulching, or "dressing," the planting site is important to keep the magnolia roots cool and to retain moisture. Spread a three to four inch layer of mulch around the tree and over the entire planting area.

Tips & Warnings

• The star magnolia is most successful when planted in the spring. If transplanting in the fall, take extra care to water, enrich the soil and fertilize. Make sure the tree is deeply watered before the first frost to help prevent winter burn. Plant in an area that is not exposed to salt.

• At maturity, the star magnolia can reach 15 feet tall and equally as wide. It is a slow grower.

• Late frost in spring can turn the fuzzy magnolia buds brown.
