Plant Health Care
A thinning canopy, spotted leaves or insects on the bark deserve a closer look. Plant health care starts by identifying the problem and the conditions behind it.
Our Certified Arborists assess your trees, shrubs and lawn. Services include watering and soil care, tree fertilization, and treatment for pests such as emerald ash borer. We recommend the work your plants need.
American Arbor Care has served Denver since 1995. We help you care for established plants and catch problems before they spread.

What Is Plant Health Care?
Plant health care combines pest management with attention to soil, water and growing conditions. We look for the cause of a problem before recommending treatment.
- Inspect plants and soil for signs of stress, disease or pests.
- Identify the problem and decide whether treatment is needed.
- Plan pruning, watering, fertilization or pest control for the site.
- Monitor the results and adjust care as conditions change.
Caring for trees in Denver’s dry climate
A tree’s symptoms do not always point to a single cause. Dry soil, compaction and pest damage can occur together. We look at the plant and its surroundings before recommending treatment.
A plant health care plan can include watering guidance, mulch, pruning and targeted treatments. The aim is to support the trees and shrubs already growing on your property and catch changes that need attention.
Tree and shrub pest management
Finding an insect does not automatically mean a tree needs spraying. We identify the pest, assess the damage and choose whether to monitor or treat. Treatment timing depends on the pest and the tree.
Insect treatments
- Aphid, mite and Japanese beetle sprays
- Mealybug, juniper scale and borer treatments
- Peach, plum, ash, lilac and bronze birch borer treatments
- Honeylocust and linden borer treatments
- Kermes scale and oak borer treatments
Elm and evergreen protection
- Elm leaf beetle, weevil and miner treatments
- European elm scale treatments
- IPS beetle sprays and trunk injections
Our team explains the treatment selected and any access restrictions before application.
Emerald Ash Borer (EAB) Protection
Emerald ash borer threatens ash trees in the Denver area. An arborist can identify your tree, assess its condition and discuss whether preventive treatment is appropriate.
We offer soil and trunk injection treatments. The choice depends on the tree’s size, condition and treatment requirements. A thinning canopy or splitting bark warrants an inspection, but visible damage alone does not identify the cause.
Read our Denver emerald ash borer guide for signs to watch for and questions to ask at an assessment.
Tree Disease Management
Spotted leaves, dying branches and a thinning canopy need a diagnosis before they need a treatment. An arborist examines the leaves, bark, trunk and growing conditions to help distinguish disease from watering or soil problems.
Our tree disease services include assessment of anthracnose, cankers and Dutch elm disease concerns. Depending on the findings, we may recommend treatment, selective pruning or changes to care. Trees with advanced decline may need removal.
Soil, roots and tree fertilization
Watering and root care
We assess soil moisture, compaction and the space available for roots. Recommendations may include deep-root watering, mulch or changes to irrigation. Watering needs vary with the tree, soil and weather.
Tree fertilization
Fertilizer is one part of plant health care. We consider the tree’s condition and growing site before recommending nutrients. Our services include deep-root fertilization and treatments for iron chlorosis when the assessment supports them.
Seasonal care
We help plan care through the growing season and dry winter periods. An inspection can bring pruning, watering and treatment needs into one plan.
A care plan for your property
Walk the property with an arborist and point out what has changed. We identify the plants, inspect the site and discuss what you want to keep healthy. You receive recommendations and an estimate for the work.
Ongoing care includes monitoring and adjustments as the plants and conditions change. A plan may combine tree pruning, pest management and soil care.

Frequently asked questions
What is plant health care?
Plant health care combines inspections, pest and disease management, watering and soil care. We identify the problem before recommending a treatment.
How do I know if my trees or shrubs need help?
Look for changes such as thinning leaves, dead branches, discolored foliage or insects on the bark. These signs can have different causes. An arborist assessment helps determine the next step.
When should plant health care treatments be scheduled?
Timing depends on the plant, the problem, insect activity and weather. We assess your trees and shrubs before planning applications or other care.
Do all trees need fertilizer?
Fertilization should respond to the tree’s needs and growing conditions. We assess the site and the plant before recommending nutrients or other soil care.
Should I treat my ash tree for emerald ash borer?
Have an arborist identify the tree and assess its condition. We can discuss preventive treatment, monitoring or removal based on the findings.
Can children and pets use the yard after treatment?
Access restrictions depend on the product and application. Our team will explain when people and pets can return to the treated area. Follow those instructions.
Do you offer ongoing care?
Yes. We offer ongoing plant health care programs as well as individual services. We recommend a plan based on the plants, the site and your goals.
