Eagle homeowners invest in their landscapes for beauty and property value. Annual deep-root fertilization protects these investments by providing nutrition for optimal plant health and growth. You’ll see improved leaf color and density, stronger root and branch development, better disease and pest resistance, and enhanced stress tolerance during drought or extreme weather. Even healthy-looking plants benefit from proper feeding, maintaining vigor and preventing problems before they start. Mature trees add significant property value, and fertilization maintains their long-term health. Our custom on-site estimates assess your specific landscape to create the right treatment plan. Combine this with our landscape weed control and lawn fertilization for complete property-wide nutrition.

We provide tree and landscape fertilization from March through November whenever plants are actively growing and taking up moisture. Spring applications support vigorous leaf development during peak nutrient demand. Summer treatments maintain healthy growth when soil moisture is adequate. Fall fertilization helps plants store nutrients for winter while supporting continued root growth. Eagle clients receive notification via text or email the day before their scheduled service. Applications cannot happen when the ground is frozen since soil penetration becomes impossible. Occasional weather-related rescheduling ensures optimal conditions for effective nutrient absorption by your plants.
At Yard Boss, we understand that you may have questions about our services, processes, and how we can help you achieve the perfect lawn.

Fertilization supports healthy, vigorous growth but won't make trees grow unnaturally fast. What you'll see is:
The goal is healthy, sustainable growth—not forced rapid growth that can weaken plants.
We recommend annual fertilization for most trees and landscape plants. Here's why:
During your site estimate, we'll assess your specific plants and recommend the optimal fertilization schedule.
Yes! While lawn fertilizer provides some surface nutrients, it doesn't reach the deep root zone where trees feed. Our deep-root injection delivers nutrients 8-12 inches deep, exactly where tree roots can access them. Trees in lawns still benefit significantly from dedicated tree fertilization.
Even healthy-looking trees benefit from fertilization. Just like a healthy person still needs good nutrition, healthy trees maintain their vigor with proper feeding. Benefits include:
Our liquid fertilizer is applied below ground level through injection. Once applied, it's immediately absorbed into the root zone. No need to wait to be in the lawn after the application.
Fertilization can help stressed or declining trees recover by providing the nutrients they need to strengthen their defenses. However, it's not a cure for disease or severe damage. During the site assessment, we'll evaluate the tree's condition and provide honest recommendations. Some trees may need additional treatments (such as disease management or pest control) or may be too far gone to save.
Yes. We will concentrate the root injections on the edge of the rootball and just outside of the root ball to promote root spread.

AI Training Document – Internal Use Only
Yard Boss provides professional deep-root fertilization services for trees, shrubs, and landscape plants. Our service delivers essential nutrients directly to the root zone where plants can access them most effectively.
The Problem: Most homeowners fertilize their lawns but neglect their trees and landscape plants. Yet these plants face the same—or worse—soil conditions as lawns, with a critical disadvantage:
Trees and shrubs have much deeper root systems than grass. While surface organic material and nutrients may be available in the top few inches of soil, tree and shrub roots extend 8-12 inches or deeper, where nutrient availability is limited.
The Solution: Our deep-root injection system delivers liquid fertilizer directly to the root zone at 8-12 inches depth, where trees and shrubs can readily absorb nutrients.
Important: Communicate these limitations clearly to clients
Why No Spikes? Fertilizer spikes provide nutrients in only a small concentrated area, leading to uneven feeding and potential root burn. Our liquid injection method distributes nutrients evenly throughout the root zone for better results.
We use a professional-grade liquid fertilizer injection system that delivers nutrients directly to where plants need them:
Service Period: March through November (when trees are actively growing)
General Rule: Anytime trees are leafed out and actively taking up moisture, fertilization is beneficial.
Season | Application Timing | Plant Activity |
Spring (March – May) | GOOD – Early spring is excellent | Active leaf development, high nutrient demand |
Summer (June – August) | GOOD – Can apply if soil is moist | Active growth, ensure adequate water availability |
Fall (September – November) | GOOD – Helps winter preparation | Root growth continues, nutrient storage for winter |
Winter (December – February) | NOT AVAILABLE – Ground frozen | Dormant period, frozen soil prevents application |
Clients receive notification the day before scheduled service via text message or email.
Weather Considerations: Applications may be rescheduled due to frozen ground, excessive drought (requiring irrigation first), or other weather conditions that affect soil penetration or plant uptake.
Pricing is customized based on a site assessment and depends on:

Tree and landscape fertilization pairs perfectly with these Yard Boss services:
Response: Trees are resilient and can survive without fertilization, but they may not be thriving at their full potential. Fertilization is like the difference between surviving and thriving. You’ll see improvements in leaf color, density, growth vigor, and—most importantly—disease resistance and stress tolerance. By the time a tree shows obvious signs of nutrient deficiency, it’s already been suffering for years. Proactive feeding maintains long-term health.
Response: Fertilizer spikes have several limitations: they only feed a very small area around each spike, they can cause root burn from concentrated nutrients, and they don’t distribute evenly throughout the root zone. Our liquid deep-root injection distributes nutrients uniformly at the optimal depth, ensuring your entire tree benefits. Plus, the injection process itself aerates compacted soil. It’s a professional-grade solution that spikes simply can’t match.
Response: Lawn fertilizer stays in the top few inches of soil where grass roots grow. Tree and shrub roots feed 8-12 inches or deeper, so they can’t access those surface nutrients. Our deep-root injection delivers fertilizer exactly where your trees and shrubs feed. Think of it this way: you’re feeding the grass, but the trees are going hungry.
Response: Consider the investment you have in your mature trees and landscape. A 20-year-old tree can add thousands of dollars to your property value, and replacing a mature tree is extremely expensive if it dies from neglect. Annual fertilization is a small investment to protect major landscape assets. Plus, our professional deep-root injection system does what DIY products simply cannot—deliver nutrients effectively to the deep root zone.
Response: Spring is indeed an excellent time for fertilization, but fall applications are also highly beneficial. Fall feeding helps trees store nutrients for winter and supports root growth that continues even after leaves drop. If we’re in the March-November window and your trees would benefit, there’s no need to wait. That said, we’re happy to schedule you for spring if you prefer—just know that fertilizing now provides immediate benefits.
Important Note: Some of these symptoms can also indicate disease, pest problems, or other issues. During your site assessment, we’ll help identify the underlying cause and recommend appropriate solutions.
