Help your trees thrive with professional tree fertilization services. Our certified arborists provide tailored nutrient solutions to promote healthier growth, combat stress, and improve soil quality for long-term tree vitality.
Tree fertilization involves providing essential nutrients to trees to improve their growth, health, and resistance to stress. Fertilizers supply nutrients like nitrogen, phosphorus, and potassium, which might be lacking in the soil. By addressing soil deficiencies, fertilization ensures your trees have the resources they need to flourish.
Trees in urban and suburban environments often face challenges like compacted soil, limited nutrient availability, and exposure to stressors such as pollution. Fertilization helps:
The cost of tree fertilization varies depending on factors like tree size, soil condition, and the type of fertilizer required. Our arborists assess your tree’s needs and provide a customized plan and quote to ensure optimal results.
The frequency of tree fertilization depends on the specific needs of the tree, soil condition, and environmental factors. Typically, trees benefit from annual or biannual applications. Our team provides expert recommendations tailored to your trees’ unique requirements.
Our certified arborists use advanced techniques and high-quality fertilizers to provide targeted care for your trees. With personalized solutions, we ensure your trees receive the nutrients they need to thrive. We also offer soil testing and ongoing care plans for sustained tree health.

Surface fertilizer applications don't reliably reach the feeder roots where trees actually absorb nutrients. Deep root fertilization uses pressurized injection to deliver a balanced nutrient solution directly into the root zone, 8 to 12 inches below grade, at multiple injection points around the tree's drip line.
This approach bypasses competition with surface vegetation, breaks through compacted soil layers, and delivers nutrients the tree can access immediately. In Chatham-Kent and Tilbury, where clay soils create low-oxygen conditions around root systems, deep injection also improves root-zone aeration, a benefit that surface application simply cannot deliver.

Tree fertilization should be done with precision, not guesswork. Your trees have specific nutrient needs, and we make sure those needs are properly assessed before any treatment is applied.

Deep root fertilization is a professional arboricultural technique that uses a pressurized soil injection probe to deliver liquid nutrients directly into a tree's active root zone. Injection points are spaced at intervals around the tree's drip line, where feeder roots are most active.
The pressurized injection also fractures compacted soil, improving oxygen penetration and water infiltration. For trees in urban settings where soil compaction is a chronic problem, this mechanical benefit can be as valuable as the nutritional one.
If your trees are showing any of the following, deep root fertilization may be part of the solution our arborist recommends:
Trees that receive regular deep-root fertilization on an appropriate schedule consistently show improved vigor, greater canopy density, stronger disease resistance, and faster recovery from seasonal stress.
Removing a mature tree and replacing it costs significantly more than a tree fertilization program that keeps the original tree healthy for another generation. It is one of the most cost-effective investments you can make in the long-term value of your landscape.

Your trees deserve informed care, not guesswork. Goodreau's certified arborists give clear answers to the most common questions about deep root fertilization.
1. How does deep root fertilization work?
A: A pressurized soil probe is inserted at multiple points around the tree's drip line, delivering a liquid nutrient solution at 8 to 12 inches depth, directly to the feeder root zone. Injection pressure also aerates compacted soil as a secondary benefit.
2. How often should trees receive deep root fertilization?
A: Most established trees benefit from deep-root fertilization every 1 to 3 years, depending on species, site conditions, and observed vigor. Our arborists will recommend a schedule based on what your trees actually need.
3. Will deep root fertilization harm my lawn?
A: No. The nutrient solution is delivered below the lawn root zone. Any minor surface marks from the probe close within a few days.
4. Can newly planted trees receive deep root fertilization?
A: Generally, we wait until a newly planted tree has completed at least one full growing season. Our arborists will advise on the right timing during your consultation.
5. What nutrients are used in deep root fertilization?
A: The blend depends on species and observed deficiencies, typically nitrogen, phosphorus, and potassium, along with micronutrients such as iron, manganese, and zinc.
6. How do I know if my tree needs deep root fertilization?
A: Signs include smaller or paler leaves, reduced canopy density, slow growth, or upper canopy dieback. Book a free arborist assessment, and we'll tell you honestly what we find.
