Problems With Planting a Magnolia Tree Beside a House

Planting trees around your house is a good idea. Not only will the branches shade your tree in the summer, trees are a beautiful part of the landscape. All too often, homeowners plant young trees close to the house, forgetting or unaware of the adult size of the tree. Magnolia trees are attractive year round. They have dark glossy leaves that are evergreen in warmer climates and bear beautiful pink or white flowers in the spring. But these trees also grow to a height 35 to 60 feet. Problems can arise with planting any tree, including a Magnolia, too close to any structure.

Tree Litter

The leaves of the Magnolia are evergreen, but they fall year round. This can cause your rain gutters to clog up when branches overhang the roof. The giant flowers of the Magnolia tree produces large seed pods which contain little red seeds favored by birds. Accumulation of foliage and seed pods litter on the roof can also begin to decompose and cause damage to roof shingles or tiles. This litter can also foster the growth of fungus—such as mold and mildew—that can adversely affect and damage your home.

Roots

Although the Magnolia tree does have a tap root, the roots of the tree extend the approximate same distance underground as the branches do above the ground. If the branches are brushing against your house, it's likely the roots are invading the foundation of your house. Your Magnolia tree should be planted at least 20 feet away from your house, according to the University of Missouri, for optimal shade benefits and to reduce the chance of damage to your home.

Branches

The branches of the Magnolia can scratch against the side of the house causing damage to siding, rain gutters and even roof tiles. Branches can also break off, damaging the structure of the house.

Pests

Small animals that nest in trees, such as rats and squirrels, can use the overhanging branches of your Magnolia as a bridge to enter your home. These animals can nest or even winter in your attic or crawl spaces, causing damage or leaving behind droppings.
