Saucer Magnolia Tree Care

The saucer magnolia or Magnolia x soulangeana is a deciduous tree that is native to Asia. It gets its name from the shape of its flowers, which resemble saucers. The tree blooms in early spring, and its flowers can be white, pink, or purple. Saucer magnolias typically live for between 20 and 50 years and develop a height and canopy spread of 20 to 30 feet.

How to Care for A Saucer Magnolia Tree

Saucer magnolias are relatively low-maintenance trees. However, they do require some care to ensure that they thrive. Here are a few tips on how to care for your saucer magnolia tree:


Saucer magnolias prefer a temperate climate. They will not tolerate extreme cold or heat. When the weather degrees drop or scorch in Texas, be sure to apply mulch so soil temperatures are better stabilized.


The ideal soil for a saucer magnolia is rich, loamy, and well-drained. Avoid planting in clay or sandy soil, as this can cause the roots to suffer.


Saucer magnolias need regular watering, especially when they are young, but allow the soil to dry out slightly between watering. Once established, they are relatively drought tolerant. However, during periods of extended drought-like summertime in Dallas, TX, you may need to water your tree more frequently.

A saucer magnolia benefits from annual fertilizer in the spring. Look for a fertilizer that is high in nitrogen and phosphorus. Avoid fertilizers with too much potassium, as this can encourage leaf drop. Be sure to always follow the instructions on the package, as excessive fertilizer can damage the roots.


Pruning is not typically necessary for a saucer magnolia. However, you may need to prune to shape the tree or remove damaged branches. If you do prune, be sure to have an ISA-Certified Arborist assess how much and when it is best to do so.

Sun Exposure

Saucer magnolias prefer full sun to partial shade.


They also need well-drained soil. If your soil is heavy or poorly drained, consider planting in a raised bed.


The flowers of a saucer magnolia tree are beautiful, but they can be messy. If you don’t want to deal with the cleanup, consider planting your tree in an area that is out of the way. They typically bloom in early spring.

What Diseases and Pests Are Saucer Magnolias Prone To?

Saucer magnolias are generally healthy trees. However, they can be susceptible to a few diseases and pests. Here are a few of the most common problems:

Verticillium wilt

This fungal disease affects the vascular system of the tree, causing the leaves to wilt and turn brown. It is most common in poorly drained soils. To prevent verticillium wilt, plant in well-drained soil and avoid overhead watering.

Powdery mildew

This fungal disease causes white powdery spots to form on the leaves. It is more common in humid climates. To prevent powdery mildew, plant in a well-ventilated area and avoid overhead watering.


These small pests suck the sap from the leaves, which can cause damage. They are most active in spring and early summer. To control aphids, hose them off with water or use an insecticidal soap.

Japanese beetles

These destructive pests can cause serious damage to a saucer magnolia. They are most active in late spring and early summer. To control Japanese beetles, use an insecticide or trap them with pheromone traps.

Saucer magnolias are beautiful trees that make a fantastic addition to any landscape. With proper care, they will thrive for many years. By following the tips above, you can ensure that your saucer magnolia tree stays healthy and blooms beautifully each spring. If you have any questions about how to care for.
