Fertilization
Feed Your Trees and Restore Growth
Edward's Tree Service provides tree and shrub fertilization to support long-term health and nutrient balance.
Trees and shrubs pull nutrients from the soil as they grow, and over time those reserves become depleted, especially in compacted soil or areas where fallen leaves and organic matter are regularly cleared away. You may notice slower growth, pale or yellowing leaves, thinning canopies, or branch dieback even when the tree receives adequate water. These are signs that the root system is not accessing the nitrogen, phosphorus, and potassium it needs to sustain normal function.
Edward's Tree Service applies granular or liquid fertilizer to the root zone using soil injection or surface broadcasting depending on the tree species, soil type, and site conditions. The fertilizer is formulated to match the specific nutrient deficiencies identified during a site evaluation. Application is timed to align with the tree's active growth periods, typically in early spring or late fall when roots are most responsive to nutrient uptake.
If your trees are showing signs of poor growth or discoloration, contact Edward's Tree Service to schedule a consultation and soil assessment.
How fertilizer is applied and absorbed
Edward's Tree Service evaluates the tree's size, age, and visible symptoms before selecting a fertilizer blend. The crew applies the product either by injecting liquid fertilizer directly into the soil around the drip line or by spreading slow-release granules across the root zone. Injection allows nutrients to reach deeper into the soil where feeder roots are most active, while surface application works well for younger trees and shrubs with shallow root systems.
After fertilization, you will notice new leaf growth within several weeks, and the color of existing foliage will deepen as chlorophyll production increases. Branch tips will begin to extend, and overall canopy density will improve over the growing season. Trees that were previously stalled in growth or losing leaves prematurely will show visible recovery as nutrient levels stabilize.
Fertilization is not a substitute for proper watering, mulching, or pest management, but it does address nutrient deficiencies that cannot be corrected through those practices alone. The crew does not fertilize trees that are severely diseased, recently transplanted, or under drought stress, as nutrient application during these periods can cause additional harm. Results vary depending on soil quality, weather, and the severity of the deficiency.
Here are answers to help you decide
Homeowners often have questions about timing, frequency, and what fertilization can and cannot fix. Below are the most common questions Edward's Tree Service receives about tree and shrub feeding programs.
How do I know if my tree needs fertilizer?
Look for yellowing leaves, stunted growth, sparse foliage, or early leaf drop that is not caused by drought or pests. A soil test can confirm nutrient deficiencies and guide the type of fertilizer used.
When is the best time to fertilize trees?
Fertilization is most effective in early spring before new growth begins or in late fall when roots are still active but the canopy is dormant. Avoid fertilizing during extreme heat or drought, as the tree cannot absorb nutrients properly under stress.
What type of fertilizer does Edward's Tree Service use?
The crew uses slow-release granular fertilizers or liquid injections formulated with nitrogen, phosphorus, and potassium based on the tree's needs. Micronutrients such as iron and manganese are added if deficiencies are detected during the site evaluation.
How long does it take to see results?
You will typically see new leaf growth and improved color within four to six weeks after application. Full recovery of a nutrient-deficient tree may take a full growing season depending on the severity of the depletion.
Will fertilization fix a tree that is already dying?
Fertilization can help a tree recover from nutrient deficiency, but it will not reverse damage from disease, root rot, or structural failure. Edward's Tree Service assesses the tree's overall condition before recommending treatment.
Edward's Tree Service applies fertilizer based on soil conditions and tree health, not on a fixed schedule. If your trees are struggling to grow or showing signs of nutrient stress, reach out to Edward's Tree Service to schedule an evaluation and treatment plan.
