7 Disease-Resistant Trees to Grow for a Thriving, Low-Maintenance Yard

Red Maple

The red maple (Acer rubrum) is one of the most widespread deciduous trees in eastern and central North America. It is cherished for its vibrant red foliage and red-tinted twigs. The cheerful tree is considered moderately disease-resistant to certain fungal diseases, such as verticillium wilt, particularly compared with Norway or silver maples.

David Fried, co-owner of Elmore Roots, notes that the red maple tree is also mostly resistant to black tar spot, a fungus that causes unsightly black spots on the leaves. Although red maples may still be affected, the chance is low, and incorporating cultural controls, such as leaf raking, can help reduce the risk of infection.

Empire Apple

The Empire apple (Malus domestica 'Empire') is a hybrid of McIntosh and Red Delicious. It is a popular choice for gardeners due to its low maintenance requirements and cold hardiness. One of its notable features is its resistance to cedar apple rust, a common fungal disease that affects many apple trees. This disease is characterized by yellow-orange spots on the leaves, often bordered in red and marked with black dots. Cedar apple rust can reduce fruit quality and cause premature leaf drop. In addition to the Empire apple, Fried highlights that other apple varieties resistant to cedar apple rust include Dolgo, Chestnut, Haralson, Liberty, Macfree, Macoun, Wolf River, Yellow Transparent, and Zestar.

Ginkgo

The ginkgo tree (Ginkgo biloba) is a durable and attractive species renowned for its unique fan-shaped leaves, which turn a brilliant yellow in the fall. This deciduous tree is exceptionally tolerant of pollution and highly resistant to diseases caused by bacteria, fungi, and viruses, making it an ideal choice for urban environments. Due to its strong, long-lasting immune system and genetic diversity, the ginkgo produces antimicrobial compounds that help protect it from various diseases and pests. To maintain its disease-resistant qualities, the ginkgo should be planted in well-draining soil and a location that receives full sun.

7 Trees You Should Never Plant Near Your House, According to Experts

American Persimmon

The American persimmon (Diospyros virginiana) is extremely resilient, low-maintenance, and naturally resistant to most pests and diseases, says Katie Brines, member of the National Garden Bureau and specialist with Stark Bro’s Nurseries & Orchards Co. The deciduous native tree has distinctive dark bark that resembles alligator skin. It features glossy green leaves that turn purple in the fall and produces small, fragrant, bell-shaped, yellowish-white flowers in the spring. The fruit is small and round, changing from green to deep orange-red, with a thin, wrinkled skin when ripe. It’s important to note that persimmon trees are dioecious, meaning that male and female flowers grow on separate trees. To ensure successful pollination and produce sweet fruit that ripens in autumn, it's essential to plant both a male and a female tree.

Southern Magnolia

Southern magnolia (Magnolia grandiflora) is a large, iconic evergreen tree known for its glossy, dark green leaves with rusty undersides and large, highly fragrant white flowers that have a lemony scent. This striking tree is low-maintenance and hardy, exhibiting a high resistance to most pests and diseases. Notably, it is resistant to oak root fungus. To ensure the tree thrives and remains strong, plant it in full sun and well-draining, acidic soil, providing it with consistent moisture, especially when young.

Kousa Dogwood

The Kousa dogwood tree (Cornus kousa) is a deciduous tree highly valued for its resistance to dogwood anthracnose, a harmful fungal infection that affects the tree's leaves, twigs, and trunk. In late spring, it displays striking white bracts and produces edible red berries with a sweet flavor reminiscent of persimmons, mangoes, and apricots. Additionally, the leaves of the dogwood have trichomes that help protect against environmental stressors and pests. This cultivar is also less susceptible to powdery mildew compared to native dogwoods. For the best disease resistance, plant the tree in well-draining, acidic soil that is enriched with compost. Prune annually to improve airflow and sunlight penetration, which strengthens the tree against diseases and pests.

Sugar Maple

Sugar maples (Acer saccharum) are large, hardy, deciduous trees renowned for their vibrant yellow, orange, and red fall colors and for their syrup production. Although they are susceptible to some widespread diseases, Fried highlights that they are notably resistant to black tar spot, much like red maples.

To minimize the risk of infection, rake fallen leaves in the spring, as the fungus that causes the disease overwinters in them. Sugar maples are sensitive to road salt, drought, and compacted soil. To ensure your tree thrives, plant it in cool, moist, well-draining, fertile soil.
