"This makes the third job that Mathias Precision has done for us. They are extremely knowledgeable and honest. If I want something done to a tree or shrub they will let me know if it is good for the plant. Other companies would just tack it onto the bid! The workers are so friendly and when the job is completed you will not find a limb or leaf left behind. I highly recommend Josh and his crew. I will never look further!"

Nourishing Trees from the Roots Up Since 2003 

Mathias Precision Tree Service has been improving tree health in St. Charles and St. Louis Counties for over 20 years. Our deep root fertilization service provides trees with essential nutrients for strong, healthy growth. This targeted approach delivers nourishment directly to the tree's root system.

Trees, like all living things, require proper nutrition. However, urban and suburban soils often lack the necessary nutrients for optimal tree health. Our Certified Arborists use specialized equipment to supply trees with the specific nutrients they need to thrive wherever they may be planted, from busy roadsides to residential yards, and everything in between.

How Deep Fertilization Works

Deep root fertilization delivers nutrients directly to a tree's root zone, ensuring efficient uptake and bypassing competition from grass and weeds. Here's our process:

  • 1
    Tree and Soil Assessment

    We evaluate your trees and soil to identify specific nutrient needs.

  • 2
    Custom Nutrient Blend

    Based on the assessment, we create a tailored mixture of essential nutrients.

  • 3
    Specialized Application

    Using high-pressure equipment, we inject the fertilizer into the soil around the tree.

  • 4
    Strategic Coverage

    We apply the mixture in a pattern from the trunk to the drip line, ensuring full root zone coverage.

  • 5
    Optimal Depth

    Injections are made 6-12 inches deep, where most feeder roots are located.

  • 6
    Slow-Release Formula

    Our fertilizer gradually releases nutrients, feeding the tree for several months.

This method not only nourishes the tree but also aerates the soil, improving oxygen levels and water penetration. The result is stronger root systems, better overall health, and increased resistance to environmental stresses.

Benefits of Deep Root Fertilization

Deep root fertilization provides a wide variety of benefits to trees across the greater St. Louis and St. Charles, MO area, including:

  • Improved root strength: Stronger root systems lead to safer, more stable trees. 

  • Better foliage color: Trees display healthier, more vibrant leaves. 

  • Increased disease and pest resistance: Proper nutrition helps trees ward off potential threats.

  • Enhanced growth: Young trees develop faster, while mature trees show renewed vigor. 

  • Better soil conditions: Fertilization improves the soil structure around trees.

  • Increased stress tolerance: Well-nourished trees better withstand environmental stresses like drought or storm damage.

Deep Root Fertilization FAQs

Treatment frequency varies based on tree needs and soil health. While traditional fertilization might occur every 2-3 years, our comprehensive soil improvement program is typically applied 3 times annually. Our arborists will recommend a customized schedule after assessing your trees and soil.

Although our method targets tree roots, it may cause temporary green spots in your lawn where the fertilizer is applied. This effect is harmless and usually evens out over time. Our arborists can discuss any concerns about lawn appearance during your consultation.

Leaf color may improve within weeks. More significant health and growth improvements typically become apparent over the next growing season. For example, fall fertilization is an investment for the future, with noticeable results the following spring.

Yes. Once injected into the soil, the fertilizer is not accessible to pets or children. You can use your yard normally immediately after treatment.

Not necessarily. Some trees may thrive with existing soil nutrients. We conduct a thorough assessment to determine which trees would benefit most from fertilization. We won’t recommend any unnecessary treatment options.
