How We Do It
Soil-first fertilization
An ISA Certified Arborist® visits your property to evaluate your trees, root zone conditions, and any visible stress symptoms. We collect soil samples and send them to a laboratory. Results reveal pH levels, nutrient content, and organic matter. Based on the assessment and soil analysis, we build a fertilization program tailored to your specific trees and site conditions. This includes product selection, application method, and timing.
Why We Do It
The essentials for healthy plants and trees
Applying the wrong product, at the wrong rate, without knowing your soil's pH and chemistry is unlikely to help—and can actively damage root systems. The proper nutrients are essential to the health and happiness of your property. We like to start at the root of the problem, and we see the results of this service as a foundational solution.
Benefits from the ground up
Longer-lasting trees
Trees under chronic nutrient stress are more vulnerable to pests, disease, and storm damage. A soil-based fertilization program addresses the root cause—literally—so your trees build genuine structural health, not just temporary green-up.
No guesswork
Every program we recommend starts with a laboratory soil analysis. You'll know exactly what your soil is deficient in and why, and every product we apply is selected to address those specific findings. That's what separates professional tree care from general-purpose garden center products.
ISA Certified Arborists
Our plant health care specialists are ISA Certified Arborists with real training in tree biology, soil science, and plant health. When they make a recommendation, it's grounded in expertise—not a sales pitch.
Frequently Asked Questions About Tree Fertilization and Soil Care
The most reliable indicators are yellowing leaves, stunted growth, thin canopy, and premature leaf drop. But visual symptoms aren’t always conclusive. A soil analysis tells you what’s actually happening in the root zone. Our arborists can conduct an on-site assessment and recommend testing if warranted.
Surface application places fertilizer on top of the soil, where it can be diluted by rain, taken up by turf grass, or blocked by compacted soil before reaching tree roots. Deep root fertilization injects fertilizer directly into the root zone under pressure, bypassing these obstacles and delivering nutrients where trees can actually absorb them. For most established trees, deep root feeding is significantly more effective.
Timing depends on the species, the deficiency being treated, and the application method. In Indiana, late fall (after leaf drop) and early spring (before bud break) are typically the most effective windows for deep root fertilization—the root system is still active and can absorb nutrients before the demands of the growing season. Our arborists will recommend timing based on your trees’ specific needs.
You can apply general-purpose fertilizer, but without knowing your soil’s pH, nutrient content, and organic matter levels, you’re essentially guessing. Incorrect fertilization can cause salt burn and nutrient toxicity, or simply have no effect. For established trees showing stress symptoms, professional assessment and treatment will be more effective and more cost efficient in the long run.
Yes. We offer ongoing plant health care programs that combine fertilization with seasonal shrub protection, pest control for trees and shrubs, disease management, and periodic monitoring. These programs are more cost effective than individual service calls and provide consistent oversight of your landscape’s health throughout the year.
Biostimulants are products that enhance a plant’s natural processes rather than directly supplying nutrients. They include mycorrhizal inoculants, humic acids, beneficial microorganisms, and other soil enhancers that improve the soil’s ability to make nutrients available to roots. We incorporate biostimulant products into fertilization programs where soil health testing indicates depleted soil microbial activity or poor soil structure—common in urban landscapes.
