Healthy Soil = Healthy Trees
The Importance of Soil Health for Tree Health
At Texas Tree Surgeons, we often say: “If you want to understand a tree’s health, start with the soil.” Soil is more than just dirt—it’s a living ecosystem that provides the foundation for a tree’s growth, strength, and longevity.
In North Texas, maintaining soil health is especially important. Our native soils vary widely—from the dense clays of the Blackland Prairie to the sandy loams of the Cross Timbers region—and urban development often disrupts natural soil conditions. That’s why understanding, protecting, and improving soil health is one of the most effective ways to support tree health.
Why Is Soil Health So Important?
Healthy soil is essential for a tree’s ability to grow, adapt, and withstand environmental challenges. Here’s how:
-
01
Soil acts as a natural reservoir, providing trees with:
- Essential nutrients like nitrogen, phosphorus, and potassium, which fuel growth and photosynthesis
- Water storage, keeping roots hydrated—especially during dry periods
- Pollutant filtration, protecting roots from toxins
When soil is rich in organic matter and well-structured, it retains moisture without becoming waterlogged and makes nutrients more accessible to tree roots.
-
02
Structural Support and Root Development
Healthy soil provides:
- Physical support, anchoring the tree’s roots and helping prevent uprooting during storms
- Ideal Soil Structure allows oxygen and water to reach roots through micropores in the soil.
- Root-friendly conditions, promoting deeper, stronger root systems
In contrast, compacted or poorly drained soil restricts root growth, reduces stability, and increases stress on the tree, especially in urban environments where heavy equipment and foot traffic are common.
-
03
Soil Microbial Life
Healthy soil isn’t just a medium—it’s an active, living ecosystem.
It includes:
- Beneficial microbes, like bacteria and fungi, break down organic material and release nutrients
- Mycorrhizal fungi, which form symbiotic relationships with tree roots to expand access to water and minerals
These invisible partners are essential to tree survival. When the microbial community is thriving, your trees are too.

How to Improve Soil Health in North Texas
Soil in the DFW Metroplex aren’t always naturally ideal for trees—but that doesn’t mean they can’t be improved.
Key practices to boost soil health:
- Add organic matter like mulch to increase organic matter and support microbial life
- Aerate compacted soils using air spading or vertical mulching to improve root access to air and water
- Avoid chemical products like weed-and-feed or chlorine-laced water that can kill beneficial organisms
- Plant native species to encourage biodiversity and long-term soil improvement
- Improve drainage to prevent waterlogging and oxygen deprivation
With regular care and the right treatments, poor soils can become vibrant, living systems that support healthy, thriving trees.

05
Signs of Poor Soil Health
If your soil is struggling, your trees will show it. Look for:
- Yellowing leaves (chlorosis) due to nutrient deficiencies
- Stunted growth or leaf drop during growing season
- Water pooling after rain (a sign of poor drainage or compaction)
- Shallow rooting or unstable trees
- Sparse canopy or dieback from root stress
- Lack of earthworms or insect activity in the soil
If you notice any of these symptoms, your trees may be suffering from underlying soil problems.
-

Soil Health = Ecosystem Health
- Improves water infiltration and reduces runoff
- Filters pollutants before they reach groundwater
- Supports native plants and pollinators
- Stores carbon and reduce atmospheric CO₂
By investing in soil health, you’re improving not just the health of your trees, but the sustainability and resilience of your entire property.

Tree Health Care

PREVENTATIVE EAB TREATMENT
If there is EAB activity within a few miles of where you live or property you manage we recommend preventative systemic insecticide treatment applied by a licensed TDA tree health care technician. EAB treatment lasts for 2 years and must be applied regularly to protect ash trees from infection.

OAK WILT TREATMENT
As oak wilt is a systemic, vascular disease, the most effective treatments consist of injecting the infected trees with a fungicidal chemical. The only currently recommended fungicide is Alamo®, a formulation of the fungicide propiconazole. The fungicide is administered through holes drilled in the root flare of the infected tree and should only be applied by Texas Department of Agriculture Licensed Applicators.

STRESSED MAGNOLIA | AFTER
This after photo was taken June 27, 2024 of a magnolia tree after receiving multiple interventions to improve its health. In addition to a tree health care plan of a deep root fertilization with Biopack plus and Sea3 applied by our TDA licensed technician the owner also fixed the irrigation and cleared the root flare. The difference in health is beautiful.

FERTILIZATION
Our Tree Health Care Programs are designed to deliver the right nutrients at the right times throughout the year. We use the highest quality soil conditioners and fertilizers that are delivered at critical points throughout the seasons to optimize the growth and health of trees.

DEEP ROOT INJECTION SERVICES
At Texas Tree Surgeons our deep root injection services provides fertilization deep into the soil. Our unique mixtures combine macro- and micro-nutrients, root growth stimulators, soil conditioners, beneficial biotics (both mycorrhizal fungi and rhizobacteria), and organic materials to cultivate the optimum natural growth environment.

ROOT PRUNING POST AIR SPADING
To correct this improperly planted tree our Tree Health Care Technicians air spade to expose the root flare and to prune away girdling roots. You can learn more about how to properly plant a tree here.

GIRDLING ROOTS
This tree was planted too deep and has several girdling roots (roots that circle the tree and do no flare out) that left unmanaged would eventually kill the tree. After air spading our Tree Health Care Technicians are pruning the roots and adjusting the soil around the tree to expose the root flare to improve tree health.

INSPECTING FOR POSSIBLE DECAY
Sometimes issues with a tree aren't clearly visible on the outside so an arborist will need to inspect the interior. An arborist does this by probing with a small knife to see how extensive the decay in a region of a tree is. Arborists are able to use this information along with other signs to determine if there are potential structural issues or possible increased chances for failure.

MEASURING DBH
The best way to approximate the size of a tree is to measure their dbh, (diameter, breast, height). This enables our arborists to estimate the amount needed for Tree Health Care products or pricing for Tree Removal.
