Surface fertilizers rarely reach the roots that matter; our targeted injections deliver life-sustaining nutrients directly to the "absorptive zone" where your tree needs them most.
In an urban forest, trees often lack the natural leaf litter and forest floor nutrients they need to thrive. If your trees are struggling with the following, they are likely nutrient-deficient:
At Eugene Tree Health Care, we don't believe in "one-size-fits-all" spikes. We customize our liquid blends based on the specific biological needs of your landscape.
A balanced, slow-release nitrogen formula designed to sustain steady growth throughout the Eugene growing season without causing the "flush" of weak, watery growth associated with cheap fertilizers.
For trees struggling with Eugene’s specific soil pH, we provide chelated iron and manganese injections that bypass soil "lockout" to restore deep, vibrant green to your leaves.
Ideal for newly planted or stressed trees, this treatment introduces beneficial fungi and humic acids to expand the root system’s reach and improve natural water absorption.
By combining potassium-rich nutrients with organic wetting agents, we help your trees retain cellular moisture and survive our increasingly dry Willamette Valley summers.
We use high-pressure professional equipment to bypass the grass and reach the "feeder roots" 6 to 12 inches below the surface.
The Deliverable: Each client receives a Nutrient Application Log, detailing the specific minerals applied and a customized watering schedule to help the tree process its new "fuel."
Eugene’s heavy clay and acidic soil profiles require a nuanced touch. Trust the team that understands the chemistry of the South Hills and the River Road area alike.
We know that a Douglas-fir in the Spencer Butte foothills has vastly different nutritional needs than a Japanese Maple in a manicured downtown garden. Eugene Tree Health Care sources our amendments locally whenever possible and tailors our application timing to the Pacific Northwest’s unique rain cycles. We don't just feed trees; we build the soil health that sustains them for generations.
Spikes concentrate nutrients in one tiny spot, often burning the roots nearby while leaving 95% of the root system hungry. Our deep-root injection ensures an even distribution of liquid nutrients across the entire root zone.
Most residential jobs are completed in 1 to 2 hours. Because the equipment is mobile and we only use small injection probes, there is very little disruption to your daily routine.
Early spring (just before bud break) and late fall (as the tree stores energy for winter) are the most effective times. This aligns with the tree's natural growth and storage cycles.
Because we inject the nutrients 6 to 12 inches deep, most of the "food" goes straight to the tree. However, you may notice a slight "greening" of the grass at the injection sites as a secondary benefit!
Yes. Since the nutrients are injected deep into the soil, there is no surface residue or "runoff" for pets or children to come into contact with.
For optimal health, we recommend deep root fertilization once a year. For trees in high-stress environments or those recovering from disease, we may suggest a bi-annual "booster" application.
