Some problems live inside the tree—not on it. Our tree injection services deliver precisely dosed treatments straight into the vascular system to control pests and disease, correct nutrient deficiencies, and reduce stress. It’s fast, focused, and ideal for sensitive sites where overspray isn’t an option.
Tree injections aren’t a one-size-fits-all fix—they’re a precise tool in a broader Plant Health Care (PHC) plan. Our Auburn-based arborists diagnose first, then choose the right active, dose, and method (microinjection or macro-infusion) for your species and site. The result: measurable improvements with minimal impact on your property, your family, and the environment.
We serve homeowners and property managers across Auburn, Kent, Renton, and nearby communities, bringing local knowledge of Puget Sound species and seasonal pressures.
Pinpoint delivery: Medicine goes inside the tree, exactly where it’s needed.
Low drift, low impact: Great near patios, play areas, water features, or dense neighborhoods.
Tackle internal pests & diseases: Effective for borers, scale, leaf miners, and vascular diseases where topical sprays can fall short.
Nutrient corrections that work: Iron/ manganese chlorosis and other deficiencies respond well to injectable nutrients.
Less frequent applications: Long-lasting control reduces repeat visits in many cases.
Data-driven dosing: Our prescriptions are based on species, DBH (trunk diameter), and site conditions.
Assessment & Diagnosis – Certified arborist evaluates species, symptoms, history, and site conditions; soil testing performed when helpful.
Custom Prescription – We select the right active ingredient (insecticide, fungicide, nutrient, or regulator), dose by trunk diameter, and timing for the best uptake window.
Preparation – Root flare is located and cleared; ports are mapped around the trunk for even distribution.
Injection / Infusion – Microinjection or macro-infusion equipment delivers the material into xylem pathways for uniform uptake.
Sealing & Cleanup – Ports are sealed neatly; work area is left clean.
Follow-Up Monitoring – We verify results and, if needed, adjust your PHC plan (watering, mulching, aeration, or pruning guidance).
Sensitive sites where spray drift is a concern (near decks, play sets, pools, water).
Tall canopies where coverage with foliar sprays would be inconsistent.
Internal feeders (borers, some scales/leaf miners) or vascular diseases.
Rapid response needed or long-lasting protection desired.
Chlorosis or proven nutrient deficits requiring direct correction.

Have questions about tree injections? This FAQ explains when injections are better than sprays, what they treat (borers, scale, chlorosis), safety around kids and pets, how long results last, pricing basics, and what to expect on service day. Don’t see your question? Call (360) 599-0727 or request a health assessment—we’ll confirm whether microinjection or macro-infusion is the right fit for your trees.
Yes. Injections keep the material inside the tree, dramatically reducing drift. We’ll provide re-entry guidance when needed.
Done properly, ports are small and placed at the root flare where the tree compartmentalizes well. We use clean bits, correct spacing, and sealing plugs to support quick closure.
Depends on the material and target. Some provide weeks to months of protection; others can last a full season or more. We’ll outline timing in your plan.
Some pests decline within weeks; canopy improvements (color, density) are typically seen over one or two growth cycles.
No. Severe decay or structural failure can’t be reversed with injections. In those cases, we may recommend pruning or removal for safety.
They’re better for certain scenarios—sensitive sites, tall canopies, internal pests, or nutrient corrections. We’ll choose the least-toxic effective method for your goals.
Not usually. Please unlock gates, secure pets, and clear the base of the trunk. We’ll handle the rest and update you after the visit.
Pricing is based on trunk diameter (DBH), the product used, number of trees, and site complexity. After your assessment, you’ll receive a clear written quote—no surprises.
Proactive care pays off. Our injection programs reduce pest pressure, correct deficiencies, and support healthier growth with minimal impact on your property.
