Landscape Attributes

Bigleaf Magnolia is a multi-stemmed deciduous tree with an upright spreading habit of growth. Its strikingly bold and coarse texture can be very effective in a balanced landscape composition.

This is a relatively low maintenance tree, and is best pruned in late winter once the threat of extreme cold has passed. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Bigleaf Magnolia is recommended for the following landscape applications;

• Accent
• Shade

Planting & Growing

Bigleaf Magnolia will grow to be about 50 feet tall at maturity, with a spread of 40 feet. It has a low canopy with a typical clearance of 4 feet from the ground, and should not be planted underneath power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 80 years or more.

This tree does best in full sun to partial shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is not particular as to soil type, but has a definite preference for acidic soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This species is native to parts of North America.
