Plant wisely today for beauty, shade, and enjoyment for generations to come.
Few things contribute more to the beauty and character of a landscape than a well-chosen tree. Trees provide shade, shelter wildlife, soften the outlines of buildings, and lend a sense of permanence to our surroundings. Some announce the arrival of spring with clouds of blossoms. Others brighten autumn with brilliant foliage. Still others stand as stately evergreens, lending structure and dignity to the landscape throughout the year.
But choosing a tree involves more than selecting one that catches your eye at the garden center. A tree is a long-term investment, and the decisions you make today may influence your landscape for decades—or even centuries.
The old gardening principle, “the right plant in the right place,” is especially important when it comes to trees. A perennial planted in the wrong location can usually be moved. A towering oak planted too close to the house presents a considerably greater challenge.
Before putting a spade into the ground, consider what you want your tree to accomplish, how large it will eventually grow, and whether your property can provide the conditions it needs to flourish.
Begin with a Purpose
Every tree should have a reason for being where it is planted.
Are you looking for shade over a patio? A flowering specimen near the entrance? A screen to provide privacy from neighboring properties? Perhaps you want to attract songbirds, produce fruit, or establish a handsome tree that your grandchildren may someday enjoy.
Different purposes call for different trees.
Shade Trees: Large deciduous trees, such as oaks, maples, and elms, can provide welcome relief from summer heat. Properly positioned, they may also help reduce cooling costs by shading buildings and outdoor living areas.
Flowering Trees: Dogwoods, redbuds, magnolias, and flowering cherries offer seasonal beauty. Many are particularly effective as specimens near entrances, patios, or garden borders.
Evergreen Trees: Hollies, certain magnolias, cedars, and other evergreens provide year-round foliage, privacy, and shelter for wildlife.
Ornamental Trees: Japanese maples, serviceberries, and other smaller trees can become focal points in modest landscapes without overwhelming their surroundings.
Fruit and Nut Trees: Apples, pears, pecans, figs, and persimmons combine ornamental value with the satisfaction of a harvest. However, their pollination, pruning, pest-management, and maintenance requirements deserve careful consideration.
Once you have established your purpose, choosing among the many available species becomes considerably easier.
Think About the Mature Tree, Not the Sapling
One of the most common landscaping mistakes is underestimating how large a tree will become.
A young tree standing six feet tall in a nursery container may look perfectly proportioned beside a house. Thirty years later, that same tree might tower over the roof, spread its branches across the driveway, or crowd neighboring plants.
Consider the Southern live oak (Quercus virginiana). Few trees are more magnificent in the Southern landscape. Its massive trunk, spreading limbs, and evergreen foliage give it an almost architectural presence.
Yet a mature live oak may develop a crown considerably wider than the average suburban lot.
Planting such a tree in a confined space is asking for trouble.
Before purchasing any tree, investigate its expected mature height and spread. Remember that published dimensions are estimates. Actual growth depends on climate, soil, available moisture, and growing conditions.
As a general guide:
- Small trees: Usually mature at less than 25 feet tall. Suitable for smaller yards, courtyards, and locations near buildings, provided adequate clearance is maintained.
- Medium trees: Generally reach 25 to 50 feet. Appropriate for moderately sized landscapes where their crowns have room to develop.
- Large trees: Often exceed 50 feet and may spread just as widely. Best reserved for spacious properties, parks, and large lawns.
Do not forget to look upward. Overhead power lines and tree branches are a poor combination.
Look downward as well. Underground utilities, drainage systems, sidewalks, foundations, and paved surfaces should all influence your planting decisions.
Tree roots generally spread well beyond the trunk, often extending outside the canopy. While healthy roots do not ordinarily penetrate sound foundations or intact pipes, they can exploit existing cracks, damaged plumbing, and favorable moisture conditions.
Allow generous space for both the tree and its roots.
Know Your Climate and Hardiness Zone
A beautiful tree is of little value if it cannot survive your winters or endure your summers.
The USDA Plant Hardiness Zone Map is a useful starting point. It divides the country into zones based on average annual extreme minimum winter temperatures.
For example, a tree rated hardy in Zones 5 through 9 should generally tolerate the winter temperatures expected within that range.
However, winter hardiness is only part of the equation.
A tree may survive winter temperatures in a particular region yet struggle with excessive summer heat, humidity, drought, or poorly drained soil.
This is particularly important in the Southeast, where long, hot summers can be more challenging for some northern species than winter cold.
Before selecting a tree, consider:
- Winter temperature extremes
- Summer heat and humidity
- Annual rainfall and seasonal drought
- Exposure to strong winds and storms
- Salt exposure in coastal locations
- Local pest and disease pressures
Whenever possible, observe which trees thrive in established landscapes nearby. Mature specimens growing successfully in your community provide valuable evidence of local adaptability.
Understand Your Soil
Trees depend upon healthy root systems, and roots depend upon suitable soil.
Some species flourish in moist, fertile ground. Others prefer sandy, sharply drained conditions. Still others tolerate heavy clay, periodic flooding, or relatively poor soils.
Before planting, determine the characteristics of your soil.
Soil Drainage
Drainage is among the most important considerations.
Trees such as bald cypress (Taxodium distichum) and river birch (Betula nigra) tolerate wet conditions better than many common landscape trees.
Other species, including flowering dogwood (Cornus florida), generally perform best in well-drained soil.
A tree planted in persistently saturated ground may suffer from inadequate oxygen around its roots, leading to decline or death.
Conversely, moisture-loving species may struggle in excessively dry locations without supplemental irrigation.
Soil pH
Soil acidity or alkalinity affects nutrient availability.
Some trees tolerate a broad range of soil pH levels, while others have more particular requirements.
Pin oaks, for example, may develop iron chlorosis when grown in alkaline soils. Their leaves become yellow while the veins remain green.
A soil test can identify pH and nutrient conditions before problems arise.
Your local Cooperative Extension office can provide guidance on soil testing and interpretation.
Soil Compaction
Compacted soil is another common obstacle to successful tree growth.
Construction equipment, repeated vehicle traffic, and heavy foot traffic can compress soil, restricting root growth and reducing the movement of air and water.
Trees planted in heavily compacted ground often struggle, even when other growing conditions appear favorable.
Where possible, improve the planting area before installing a tree and protect the surrounding soil from unnecessary traffic.
Consider Sunlight and Exposure
Not all trees require full sun.
Many flowering trees naturally grow beneath the open canopy of larger woodland trees, where they receive filtered sunlight.
Flowering dogwoods, for example, often benefit from some afternoon shade in hot Southern climates.
Crape myrtles (Lagerstroemia spp.), on the other hand, generally flower most abundantly in full sun.
Japanese maples may appreciate protection from intense afternoon sunlight, particularly in regions with hot summers.
Observe your proposed planting location throughout the day.
Does it receive uninterrupted sunlight? Morning sun and afternoon shade? Deep shade beneath established trees?
Remember that sunlight patterns change with the seasons. A location receiving full winter sun may be shaded by deciduous trees during summer.
Choose a species suited to the conditions that actually exist rather than trying to force a favorite tree into an unsuitable location.
Choose Trees That Suit the Character of Your Landscape
A tree should complement its surroundings.
The broad, sweeping branches of a live oak look perfectly at home beside an old Southern farmhouse or along a spacious avenue. The same tree may eventually overwhelm a small courtyard.
A graceful Japanese maple might be ideal beside a garden path, while a stately Southern magnolia could serve as a magnificent specimen on a larger lawn.
Consider the architecture of your home, the proportions of your property, and the appearance of nearby plantings.
Formal landscapes may benefit from trees with strong, symmetrical forms. Naturalistic gardens often look better with species displaying irregular branching patterns and a more relaxed character.
In historic neighborhoods, traditional regional trees can help preserve the established character of the streetscape.
There is considerable wisdom in studying older landscapes. Trees that have flourished for generations often reveal what works particularly well in a given place.
Nevertheless, tradition should be tempered with judgment. Some species once planted extensively are now recognized as invasive, structurally weak, or unusually susceptible to pests and diseases.
The best landscape combines the lessons of experience with sound modern horticulture.
Native Trees Deserve Special Consideration
Native trees are often excellent choices because they have evolved within the region's climate and ecological conditions.
They can also provide valuable food and habitat for native birds, insects, and other wildlife.
In the southeastern United States, several particularly useful native trees include:
Southern Live Oak (Quercus virginiana)
A magnificent shade tree for large landscapes. Its spreading branches and enduring presence make it one of the defining trees of the coastal South.
Eastern Redbud (Cercis canadensis)
A small to medium-sized tree celebrated for its rosy-purple flowers in early spring. It works well in woodland gardens and smaller landscapes.
Flowering Dogwood (Cornus florida)
A beloved understory tree with showy spring bracts, attractive autumn foliage, and red fruits enjoyed by birds.
Southern Magnolia (Magnolia grandiflora)
An impressive evergreen with glossy leaves and large, fragrant white flowers. Cultivars vary considerably in mature size, making careful selection important.
American Holly (Ilex opaca)
A handsome evergreen that provides year-round structure and valuable wildlife habitat. Female trees produce bright red berries when compatible male pollen is available.
Bald Cypress (Taxodium distichum)
A distinctive deciduous conifer particularly well adapted to moist soils. Its soft green foliage turns a warm russet color before falling in autumn.
Serviceberry (Amelanchier spp.)
A graceful small tree offering spring flowers, edible fruits, and attractive autumn color. Select species adapted to your particular region and summer climate.
Native status alone does not guarantee success. A tree native to a wet floodplain may be poorly suited to a dry, exposed hillside, even within the same state.
The goal is to choose a tree native—or otherwise well adapted—to the particular conditions of your property.
Don't Overlook Maintenance Requirements
Every tree requires some care, especially during establishment. However, maintenance demands vary considerably.
Before planting, ask yourself a few practical questions.
Will the tree drop large quantities of fruit, nuts, or seedpods onto a driveway or patio?
Does it produce surface roots that may interfere with mowing?
Are its branches prone to breaking during storms?
Will it require regular pruning to maintain clearance over sidewalks or roads?
Is it susceptible to serious local diseases or insect pests?
Sweetgums, for example, are beautiful native trees with excellent autumn color, but their spiny seed balls can be troublesome in heavily used lawn areas.
Pecan trees may provide delicious nuts and welcome shade, but they also produce falling branches, leaves, husks, and nuts that require cleanup.
Crape myrtles are popular for their long flowering season and attractive bark, but selecting a cultivar too large for its location often leads to unnecessary and disfiguring pruning.
The solution is not to avoid these trees altogether. It is to understand their characteristics and place them appropriately.
A tree that fits its surroundings naturally will generally require less corrective maintenance throughout its life.
Plant with Storms in Mind
In regions subject to thunderstorms, hurricanes, ice storms, or heavy snowfall, structural strength deserves particular attention.
Trees with weak branch attachments, included bark, or poor branching structure may be more susceptible to damage.
Proper species selection, sufficient rooting space, and good structural pruning during a tree's early years can reduce certain risks.
Avoid planting large trees where their eventual size will create unavoidable conflicts with buildings, power lines, or heavily traveled areas.
Remember, however, that no tree is entirely storm-proof.
Even strong, healthy trees can fail under extreme conditions, particularly when soils become saturated and winds are severe.
For large established trees near buildings, periodic inspection by a qualified arborist is a sensible precaution.
Give Your Tree a Good Beginning
Even the best tree for a particular location may fail if planted improperly.
Autumn is often an excellent time to plant trees in much of the Southeast. Cooler temperatures reduce moisture stress, while relatively warm soils may allow roots to continue developing before winter.
In colder climates, spring planting may be preferable for certain species or sites.
Whenever you plant, follow a few essential principles.
Plant at the Proper Depth
Locate the root flare—the area where the trunk broadens into the uppermost structural roots.
This should be visible at or slightly above the surrounding soil surface after planting.
Planting too deeply is a common cause of long-term tree decline.
Dig a Wide Planting Hole
The planting hole should generally be two to three times wider than the root ball, but no deeper than necessary.
Wide planting holes encourage roots to expand into the surrounding soil.
Use the Existing Soil
In most situations, backfill with the native soil removed from the planting hole rather than creating a small pocket of heavily amended soil.
This encourages roots to establish themselves in the surrounding ground.
Water Thoroughly
Newly planted trees require consistent moisture while their roots become established.
Water deeply and adjust frequency according to rainfall, soil drainage, weather, and the tree's needs.
Avoid both prolonged drought and waterlogged conditions.
Apply Mulch Properly
Spread two to three inches of organic mulch over the root zone, keeping it several inches away from the trunk.
Mulch helps conserve moisture, moderate soil temperatures, and reduce competition from grass and weeds.
Never pile mulch against the trunk in the familiar but harmful "mulch volcano."
Avoid Unnecessary Staking
Trees develop stronger trunks when allowed some natural movement.
Stake only when necessary to keep a newly planted tree upright, and remove temporary supports once the tree is sufficiently established.
Plan for the Landscape You Want Tomorrow
Trees are among the few things we plant with the reasonable expectation that others will enjoy them long after we are gone.
A well-placed shade tree may eventually shelter children at play, provide a resting place on summer afternoons, or become a familiar landmark for generations.
A poorly chosen tree, on the other hand, may eventually require expensive pruning or premature removal.
It pays to think beyond the immediate appearance of the landscape.
Imagine the tree ten, twenty, or fifty years from now.
Will it still have room to grow?
Will its shade be welcome?
Will its branches complement the house rather than crowd it?
Will it contribute to the beauty and usefulness of the property?
These are questions worth asking before planting.
A Final Thought
There is an old saying that the best time to plant a tree was twenty years ago, and the second-best time is today.
There is wisdom in that sentiment, but one important qualification deserves mention: The best time to plant a tree is when you have chosen the right tree for the right place.
Take time to understand your landscape. Consider your climate, soil, available space, and long-term goals. Choose a species that will flourish without constant intervention.
Then plant it carefully, tend it faithfully, and give it room to grow.
The reward may be a living legacy of beauty, shelter, and shade—one that outlasts the gardener who planted it.
