Trees for Specific Purposes: Best Trees To Plant In Tennessee
Selecting the right tree for a specific purpose requires understanding its growth characteristics and how it interacts with its environment. Factors such as mature size, root system, and leaf density are crucial considerations for optimal results. Choosing appropriately will ensure the tree thrives and fulfills its intended function in the landscape.
Trees for Shade
Trees providing ample shade possess large canopies and dense foliage. The extent of shade cast depends on both canopy size and leaf density. A large, dense canopy will create a more substantial shaded area compared to a smaller, less dense one. The ideal tree for shade will also have a relatively fast growth rate to quickly establish a significant canopy.
Examples of shade trees well-suited to Tennessee include the American Sycamore (Platanus occidentalis), known for its massive size and broad, spreading branches, and the Pin Oak (Quercus palustris), which develops a dense, rounded crown with deep shade. The Red Maple (Acer rubrum) also offers excellent shade, particularly cultivars chosen for their size and density.
Trees for Windbreaks
Windbreaks require trees with specific characteristics to effectively reduce wind speed and protect structures or crops. Height is a critical factor, as taller trees intercept more wind. A dense canopy, often achieved through multi-stemmed growth or close planting, further enhances wind reduction. The root system should be robust and extensive to anchor the trees against strong winds.
Resilience to wind damage is paramount, requiring trees with flexible branches that bend rather than break. Good choices for windbreaks in Tennessee include the Eastern Redcedar (Juniperus virginiana), known for its dense, upright growth habit and deep root system, and various species of Leyland Cypress (x Cupressocyparis leylandii), a fast-growing conifer known for its tolerance of harsh conditions and wind resistance.
The Green Ash (Fraxinus pennsylvanica) also offers some windbreak capabilities with its rapid growth and fairly resilient branches, but it is crucial to note its vulnerability to the Emerald Ash Borer.
Trees with Attractive Fall Foliage
Many deciduous trees native to or thriving in Tennessee display vibrant fall colors. The timing and intensity of these colors vary depending on the species and environmental factors such as temperature and rainfall. Peak color typically occurs in late October and early November, but can shift based on the year’s weather patterns.
- Sugar Maple (Acer saccharum): Displays a range of colors from brilliant yellow to fiery orange and red.
- Red Maple (Acer rubrum): Exhibits scarlet, crimson, and orange hues, often exhibiting intense color early in the season.
- Sweetgum (Liquidambar styraciflua): Known for its star-shaped leaves that turn shades of yellow, orange, red, and purple.
- Black Gum (Nyssa sylvatica): Provides a stunning display of scarlet, crimson, and purplish-red tones.
- Sassafras (Sassafras albidum): Offers a unique palette of yellow, orange, and red, with some leaves exhibiting a mix of colors.
Maintaining Newly Planted Trees
Successful tree establishment in Tennessee requires diligent care following planting. Factors such as proper planting technique, consistent watering, and appropriate mulching significantly influence a young tree’s survival and long-term health. Ignoring these crucial steps can lead to stunted growth, susceptibility to disease, and even mortality.
Proper Tree Planting Techniques in Tennessee
Planting a tree correctly is paramount for its survival. The process begins with selecting the appropriate planting site, considering sunlight requirements, soil drainage, and mature size of the tree species. Digging a hole twice as wide as the root ball but no deeper is crucial to avoid root circling. Gently remove the container or burlap, ensuring no roots are constricted.
Place the tree in the hole, ensuring the top of the root ball is level with the surrounding ground. Backfill with the excavated soil, avoiding amendments unless the soil is severely deficient. Firmly pack the soil around the base of the tree to eliminate air pockets. Water thoroughly after planting.
Watering and Mulching Newly Planted Trees
Consistent watering is vital, especially during the first year. Newly planted trees require regular watering, especially during dry spells. The frequency depends on weather conditions and soil type but aim for deep, infrequent watering rather than shallow, frequent watering to encourage deep root growth. Mulching helps retain soil moisture, regulate soil temperature, and suppress weeds. Apply a 2-3 inch layer of organic mulch, such as shredded bark or wood chips, around the base of the tree, keeping it a few inches away from the trunk to prevent rot.
Common Tree Diseases and Pests in Tennessee and Their Management
Tennessee’s diverse climate and landscape support a variety of tree diseases and pests. Early detection and appropriate management strategies are critical to minimize damage and protect tree health.
- Oak Wilt: A fungal disease affecting oak trees, characterized by leaf discoloration and wilting. Prevention involves avoiding wounding oak trees during the growing season and promptly removing infected trees. Treatment options are limited and often unsuccessful.
- Anthracnose: A fungal disease affecting various hardwood trees, causing leaf spots, blight, and twig dieback. Good sanitation practices, such as removing infected leaves and branches, can help manage the disease. Fungicides may be necessary in severe cases.
- Emerald Ash Borer: An invasive beetle that attacks ash trees, causing significant damage and mortality. Early detection is crucial, and treatment options include insecticide injections. Removal of severely infested trees is often necessary.
- Aphids: Small, sap-sucking insects that can infest many tree species. Natural predators, such as ladybugs, can help control aphid populations. Insecticidal soaps or horticultural oils can be used for more severe infestations.
- Spider Mites: Tiny mites that feed on tree leaves, causing stippling and webbing. Regular monitoring and water sprays can help control spider mite populations. Miticides can be used in severe cases.
