Deep Root Fertilization in San Angelo, TX
San Angelo’s alkaline soil starves trees of the nutrients they need. Our deep root fertilization program delivers mycorrhiza and chelated iron directly to the root zone where it matters most.
Why San Angelo Trees Need Deep Root Fertilization
Trees in San Angelo face a challenge most homeowners don’t think about: the soil. West Texas soil is highly alkaline, which locks up iron and other essential minerals before tree roots can absorb them. The result is chlorosis, the yellowing of leaves caused by iron deficiency, which you see on pecan, live oak, and other species across the area. Left untreated, nutrient-starved trees decline slowly, becoming more vulnerable to insects, disease, and drought stress.
Surface fertilizers don’t solve this problem. Nutrients applied to the top of the soil either wash away with irrigation or never reach the feeder roots where absorption actually happens. Deep root fertilization is different. We inject a nutrient solution directly into the root zone, 8 to 10 inches below the soil surface, where the tree’s feeder roots can take it up immediately.
What we inject:
Our fertilization program uses a mycorrhiza inoculant with 7% chelated iron and eight essential minerals critical for tree growth. Mycorrhiza is a beneficial fungus that colonizes the root system and dramatically expands the tree’s ability to absorb water and nutrients from the surrounding soil. Think of it as extending the root network far beyond what the tree can build on its own. The chelated iron is formulated to remain available in alkaline soil, directly addressing the iron deficiency that’s so common in our area.
This is a long-term investment in your tree’s health. Mycorrhiza establishes itself in the soil and continues working between applications. We recommend yearly treatments to maintain and build on the soil biology over time. Trees that receive consistent deep root fertilization develop stronger root systems, denser canopies, and significantly better resistance to the stresses that West Texas weather puts on them.
How Deep Root Fertilization Works
Assess the Tree's Condition
We evaluate the tree's species, size, and visible health indicators. Yellowing leaves, sparse canopy, and slow growth are common signs that nutrient deficiency is the issue.
Inject Below the Root Zone
Using specialized equipment, we inject the mycorrhiza and mineral solution 8 to 10 inches below the soil surface. This places the nutrients directly where the feeder roots can absorb them, bypassing the alkaline topsoil that blocks uptake.
Let the Biology Work
Mycorrhiza colonizes the root system over time, expanding the tree's nutrient absorption capacity. You'll typically see improvement in canopy color and density within one growing season.

Deep Root Fertilization FAQ
How much does deep root fertilization cost?
Cost depends on the number of trees, their size, and the condition of the soil. Most residential deep root fertilization jobs in San Angelo range from $100 to $300 per tree. We provide a quote after evaluating your trees and property. Call (325) 374-8896 to schedule.
How often should trees be fertilized?
We recommend deep root fertilization once a year for most trees in San Angelo. The inoculant we use establishes itself in the soil and continues working between applications, but yearly treatments maintain and build on that foundation. Trees under significant stress or in particularly poor soil may benefit from an initial treatment followed by a second application six months later.
When is the best time for deep root fertilization in San Angelo?
Fall and early spring are ideal for deep root fertilization in San Angelo. Fall applications give the treatment time to colonize the root system before winter dormancy, and the tree enters spring with a stronger nutrient base. Spring applications support the heavy growth period when trees need the most energy. We offer treatments year-round, but these two windows produce the best results.
What's the difference between deep root fertilization and regular fertilizer?
Regular surface fertilizers sit on top of the soil where they’re exposed to runoff, evaporation, and the alkaline conditions that lock up nutrients before roots can absorb them. Deep root fertilization injects the solution directly into the root zone, 8 to 10 inches below the surface, where feeder roots can take it up immediately. It also builds long-term soil biology that regular fertilizer doesn’t provide.
