Plant a tree so the root flare, the point where the trunk widens into the first structural roots, sits at or slightly above the surrounding soil line. Nursery stock is frequently potted with excess soil covering the flare, so the correct depth is measured from the flare rather than from the top of the container. In New Orleans, where soil stays wet and decay moves fast, a buried flare is the most common reason young trees die slowly. Big Easy Tree Removal helps New Orleans property owners plant at the right depth and correct trees that were set too deep.

Depth is the quietest way to kill a tree. There is no dramatic moment, no obvious symptom in the first season, and no single day when anything visibly goes wrong. A tree planted three inches too deep can look perfectly healthy for two years, thin out in the third, and be gone by the fifth, and almost nobody connects the death back to the afternoon it was planted. In New Orleans this happens more often than elsewhere, because our soil holds moisture against a buried trunk and decay progresses quickly in the heat and humidity. The good news is that depth is entirely within your control and costs nothing to get right. Here is how Big Easy Tree Removal approaches it.
The root flare is where the trunk widens outward into the first major structural roots. It must be visible at or slightly above the finished soil line, and it is the only reliable reference point for planting depth.
Everything else is unreliable. The soil surface in a container is not a depth guide, because nursery production frequently ends up with several inches of media above the actual flare after repeated potting up. Measuring from the top of the pot can bury the tree before it even leaves the driveway.
Locating the flare takes a minute. Before planting, gently scrape the surface soil away from the trunk with your fingers or a hand tool until you find the point where the trunk stops being a straight column and begins to spread. On some container stock you will remove two or three inches of media to reach it. That removed depth is exactly the error you just avoided.
A healthy planted tree should show a visible taper at the base, like the bottom of a wine bottle. If the trunk enters the ground like a telephone pole, straight-sided with no flare, it is too deep. That single visual check is the fastest way to evaluate any tree, planted by you or by someone else.
Bark below ground behaves differently from bark above it, and that is the whole mechanism.
Trunk bark evolved to be exposed to air. Buried, it sits in constant moisture, and over time it breaks down. Decay organisms colonize the softened tissue, and the vascular system just beneath the bark, which moves sugars from the leaves down to the roots, is progressively damaged. The tree starves slowly from the roots up.
South Louisiana accelerates every part of that. Soil here holds moisture rather than shedding it, so buried bark stays wet nearly year round. Warm temperatures through most of the year keep decay organisms active far longer than in colder regions. And a high water table means the soil around a buried trunk is often genuinely saturated rather than merely damp.
There is a second failure mode. Trees planted deep frequently develop girdling roots, which circle the buried trunk instead of growing outward. As both the root and the trunk expand, the root presses into the trunk and constricts it. Girdling roots are a leading cause of trees that fail at the base during storms despite appearing healthy in the canopy.
Depth also compromises anchorage. Structural roots that should spread laterally near the surface end up too low, in the oxygen-poor zone, where they develop poorly. A tree with a weak, deep root plate in saturated soil is exactly the tree that leans after a wet hurricane season.
| Stock type | Where to measure from | Common mistake |
|---|---|---|
| Container grown | Root flare, after scraping back excess media | Using the pot soil line as the depth guide |
| Balled and burlapped | Root flare, after removing soil from the ball top | Leaving burlap and wire covering a buried flare |
| Bare root | Where roots visibly branch from the stem | Planting in a narrow hole with roots bent downward |
| Field dug on a wet site | Flare set above grade on a mound | Planting level with grade where water stands |
On genuinely wet sites, planting slightly high is not a compromise, it is the correct method. Setting the flare two to four inches above surrounding grade and tapering soil out into a broad mound puts the root system above the zone that stays saturated.
No. Deep planting reduces stability rather than improving it, because structural roots end up in low-oxygen soil where they develop poorly.
The instinct is understandable, particularly in a place that takes hurricanes seriously. But anchorage comes from a wide, well-developed root plate near the surface, not from depth. A tree planted correctly and allowed to develop lateral structural roots is considerably more stable than the same tree buried deeper. Where a young tree genuinely needs support, temporary staking is the answer, removed within about a year.
Two to three inches is right, spread across the root zone and pulled back several inches from the trunk so bark is never covered.
Mulch piled against a trunk creates the same problem as planting too deep, holding moisture against bark that needs air. In this climate the result is decay at the base. The volcano-shaped mulch mound seen in a lot of landscaping is actively harmful, and correcting it is a five-minute job with immediate benefit.
Yes, and it is why the hole should never be dug deeper than the root ball. Loosened soil under a root ball compresses under the tree’s weight, and the tree sinks with it.
A tree planted at exactly the right depth into a hole with a loosened bottom can be two inches too deep within a year through settling alone. Leaving the base of the hole undisturbed, so the root ball rests on firm ground, eliminates this entirely.
Diagnosis is straightforward once you know what to look at, and it is worth doing on any tree planted in the last several years.
Timing helps confirm it. Depth-related decline typically appears two to five years after planting, which is late enough that most people have stopped thinking about how the tree was installed. A young tree that looked fine and then began fading on that timeline is a strong candidate.
The outcome depends heavily on how long the tree has been buried and how far along any decay has progressed.
On a recently planted tree, correction is usually straightforward. Excavating carefully down to expose the flare, or lifting and resetting the tree at the proper height while it is still small, both work well. The sooner this happens, the better the result, and a tree caught within a year or two often recovers completely.
On an established tree, lifting is not an option and the work becomes careful soil removal. Excess soil is excavated away from the trunk to expose the flare, ideally using techniques that clear soil without damaging bark or roots. Girdling roots found during that process may need cutting, which is a judgment call, since removing a large girdling root has its own consequences for stability and health.
Two cautions matter. Do not excavate aggressively around a mature trunk with a shovel, since wounding bark that is already compromised makes things worse. And where decay is extensive around the base, correction may not save the tree, in which case the real question becomes whether it is now a hazard. That assessment should come before any decision about tree removal.
For trees caught early enough to save, supporting recovery matters as much as the excavation itself. Relieving compaction, correcting drainage, and where a soil test justifies it, targeted fertilization can help a tree rebuild while the corrected flare dries out.
Big Easy Tree Removal is locally owned and operated, and depth is the detail that separates a tree that thrives in New Orleans from one that quietly fails. Whether the job is planting new stock correctly or diagnosing why a five-year-old tree is thinning, the base of the trunk is the first place worth looking.
We serve New Orleans, Kenner, Metairie, Gretna, River Ridge, Harahan, Laplace, Hammond, and throughout Louisiana.

So the root flare sits at or slightly above the surrounding soil line. Measure from the flare, not from the top of the container soil.
The point where the trunk widens outward into the first major structural roots. A correctly planted tree shows a visible taper at the base.
Soil here holds moisture against buried bark year round and warm temperatures keep decay organisms active, so buried trunks break down faster.
Often yes, especially within the first few years. Excess soil is excavated away to expose the flare, and young trees can sometimes be lifted and reset.
No, the opposite. Anchorage comes from a wide root plate near the surface, and deep planting pushes structural roots into oxygen-poor soil.
Two to three inches over the root zone, pulled back several inches from the trunk. Mulch touching bark causes the same decay as burying the trunk.
The optimal soil depth for planting a tree depends on the size of the tree and its root system. Generally, young trees should be planted with the root ball slightly above or at ground level, while more established trees should be planted with their roots at least 8 to 12 inches deep. Planting a tree too deeply can lead to stem rot and girdling roots, while planting it too shallow can lead to windrock, dehydration and reduced root growth. Therefore, when planting a tree it is important to make sure the root system is firmly set in place at the correct soil depth for maximum long-term growth and stability.
The signs of a tree that has been planted too deep include wilting and yellowing leaves, root rot, poor growth, and weak anchorage in the soil. The stem may also appear darker than usual, with shallow roots creating a mound at the top of the soil surface.
On the other hand, signs of a tree that has been planted too shallow are visible roots near the surface of the ground, an overall airy or spindly appearance, and most notably, an unbalanced root-to-shoot ratio. Additionally, if planted too shallow the tree may struggle to access water and nutrients in the soil.
The best way to determine the right depth to plant a tree is to take into account the type of tree being planted, the region it is being planted in, and the soil conditions. Generally speaking, most trees should be planted at a depth that covers their root ball or root mass, so that the trunk flares outward from where it has been planted.
When planting in different types of soil, such as clay or sand, more depth may be necessary. In clay soils, deeper planting helps prevent girdling due to roots unable to penetrate through hardpan layers deep down. In sandy soils, not planting deep enough can lead to shallow root systems that are more prone to drought conditions.
Making sure your tree gets off to a healthy start is key; generally speaking two-thirds of the root mass should be below ground level and one-third above ground level. When planting bare-root trees (or trees with exposed roots) you can also take advantage of certain soil amendments, such as peat moss or compost, for better root formation as well as additional insulation when winter temperatures drop too low.
Overall, determining the right depth for tree planting depends largely on both the species and the location being planted in; taking note of these can help ensure your new tree is set up for success from day one!
