Our Tree Care Service Includes

United Tree Care provides complete tree care services addressing all aspects of tree health:

Professional Tree Health Evaluation

United Tree Care arborists conduct thorough health evaluations of your trees. We examine foliage, bark, branches, trunk, and root collar for signs of disease, pest damage, stress, or decline. Health evaluations identify current problems and potential future issues.

Disease Identification and Treatment

Our specialists identify fungal diseases, bacterial infections, and viral problems affecting trees. We recommend appropriate treatments, including fungicide applications, pruning diseased areas, or cultural practices that support recovery.

Pest and Insect Management

United Tree Care identifies pest infestations, including borers, scale insects, aphids, and other damaging insects. We recommend integrated pest management approaches that control pests while protecting beneficial insects and the environment.

Soil Analysis and Amendment

Soil conditions directly affect tree health. United Tree Care can arrange soil testing to evaluate pH, nutrient levels, and soil structure. We recommend amendments that improve soil quality and support healthy root growth.

Tree Fertilization

Proper fertilization provides nutrients trees need for healthy growth. United Tree Care applies appropriate fertilizers based on soil conditions, tree species, and growth goals. We use slow-release formulations that provide long-term benefits.

Root Care and Management

Healthy roots are the foundation of healthy trees. United Tree Care evaluates root systems, addresses compaction, improves drainage, and treats root diseases. Root care is often overlooked but critical for tree health.

Water Management

Proper watering is essential for tree health. United Tree Care provides guidance on irrigation needs, identifies drought stress, and recommends watering strategies for different seasons and conditions.

Mulching Services

Proper mulching protects roots, conserves moisture, moderates soil temperature, and improves soil quality. United Tree Care applies mulch correctly—at appropriate depth and distance from trunks.

Crown Care and Canopy Management

Beyond basic pruning, United Tree Care manages crown health through selective branch removal, deadwood elimination, and techniques that improve air circulation and light penetration.

Plant Health Care Programs

United Tree Care offers ongoing plant health care programs with regular visits, monitoring, treatments, and maintenance. Programs are customized to your landscape needs and provide consistent care throughout the year.

Stress Management

United Tree Care offers ongoing plant health care programs with regular visits, monitoring, treatments, and maintenance. Programs are customized to your landscape needs and provide consistent care throughout the year.

Trees experience stress from drought, compaction, construction damage, pollution, and other factors. United Tree Care identifies stress symptoms and implements treatments that help trees recover.

Growth Regulation

For some situations, controlling growth is beneficial. United Tree Care can apply growth regulators that slow growth, reduce pruning needs, or redirect energy toward root development and health.

Seasonal Care

Tree needs to change with the seasons. United Tree Care provides seasonal care, including spring fertilization, summer watering guidance, fall preparation, and winter protection for sensitive species.

Our Tree Care Service Includes

Improves Tree Health and Vigor

Regular professional care keeps trees healthy, vigorous, and attractive. Proper nutrition, disease prevention, and stress management produce trees with dense foliage, strong growth, and resistance to problems. Healthy trees are more beautiful, provide better shade, and contribute more to your landscape than struggling or declining trees.
Key health benefits include:
  • Stronger growth and vitality
  • Better resistance to disease and pests
  • Improved foliage density and color
  • Enhanced flowering and fruiting
  • Longer tree lifespan

Prevents Disease and Pest Problems

Preventive care catches problems early when they’re easier and less expensive to treat. Regular monitoring identifies issues before they become severe. Early treatment often prevents tree loss. Healthy trees are naturally more resistant to disease and pest attack. Professional care maintains tree vigor that helps trees defend themselves.

Extends Tree Lifespan

Trees receiving proper care live longer, healthier lives. Professional maintenance prevents premature decline and extends the productive life of your trees by decades. The investment in ongoing care is far less expensive than replacing mature trees that have died from neglect or preventable problems.

Increases Property Value

Healthy, well-maintained trees add significant value to properties. Professional tree care maintains and enhances this value. Properties with healthy trees are more attractive to buyers and command higher prices. Mature trees are considered valuable assets in real estate valuations. Proper care protects this investment.

Reduces Long-Term Costs

Preventive care and early treatment are far less expensive than dealing with advanced problems or tree removal. Regular maintenance reduces the likelihood of expensive emergencies. Healthy trees require less intervention and fewer treatments over time. Investment in care reduces overall tree management costs.

Improves Landscape Appearance

Healthy trees are more attractive with better foliage, stronger growth, and improved form. Professional care maintains the beauty of your landscape and keeps trees looking their best. Well-maintained landscapes create better first impressions and provide more enjoyable outdoor spaces.

Enhances Environmental Benefits

Healthy trees provide maximum environmental benefits, including air purification, carbon sequestration, oxygen production, and wildlife habitat. Professional care ensures trees deliver these benefits effectively.

Provides Peace of Mind

Knowing your trees are being monitored and cared for by professionals provides peace of mind. Regular care catches problems before they become emergencies, reducing stress and unexpected expenses.

Wherever you are in Northern Virginia, our team is ready to assist you with your tree Care needs.

Common Tree Health Problems

  • Fungal Diseases Fungal infections, including anthracnose, leaf spot, powdery mildew, and root rot, affect tree health. United Tree Care identifies fungal problems and recommends appropriate treatments, including fungicide applications and cultural practices.
  • Pest Infestations: Insects, including borers, scale, aphids, bagworms, and others, damage trees. Early identification and treatment prevent serious damage. United Tree Care uses integrated pest management for effective, environmentally responsible control.
  • Nutrient Deficiencies: Trees may lack nutrients needed for healthy growth. Symptoms include yellowing leaves, stunted growth, or poor vigor. Soil testing and appropriate fertilization correct deficiencies.
  • Drought Stress: Insufficient water causes wilting, leaf drop, branch dieback, and increased susceptibility to disease. Proper irrigation and drought management help trees survive dry periods.
  • Soil Compaction: Compacted soil restricts root growth and reduces water and nutrient availability. Compaction is common in construction areas and high-traffic zones. Soil amendment and aeration relieve compaction.
  • Root Problems: Root diseases, damage, or poor development affect overall tree health. Symptoms appear in the canopy as decline, wilting, or dieback. Root care is critical for tree recovery.
  • Environmental Stress: Pollution, road salt, temperature extremes, and other environmental factors stress trees. United Tree Care identifies stress symptoms and recommends management strategies.
  • Construction Damage: Construction activities damage roots, compact soil, and injure trunks. Trees affected by construction require specialized care to recover. United Tree Care provides construction impact assessment and recovery treatments.

Frequently Asked Questions About Tree Care

How often should trees be professionally evaluated?

United Tree Care recommends annual tree health evaluations for most properties. Mature trees, trees with known problems, or trees in high-value locations may benefit from more frequent monitoring. Annual evaluations catch problems early and allow timely treatment.

What does a tree health evaluation include?

Tree health evaluations include examination of foliage, branches, trunk, and root collar for signs of disease, pests, stress, or structural problems. United Tree Care arborists assess overall vigor, identify concerns, and recommend treatments or management practices.

Do all trees need fertilization?

Not all trees require fertilization. Trees growing in healthy soil with adequate nutrients may not need fertilizer. However, many landscape trees benefit from supplemental nutrition. United Tree Care evaluates soil conditions and tree health to determine fertilization needs.

How can I tell if my tree is healthy?

Healthy trees have full canopies, good foliage color, normal growth, and the absence of visible problems. Signs of poor health include sparse foliage, yellowing leaves, dead branches, visible pests, fungal growth, or declining vigor. United Tree Care can evaluate your trees professionally.

What causes trees to decline?

Tree decline results from multiple factors, including disease, pests, drought, soil problems, root damage, environmental stress, or age. Often, multiple factors contribute to decline. Professional evaluation identifies causes and appropriate responses.

Can dying trees be saved?

Some declining trees can recover with proper treatment. Success depends on the cause of decline, severity of damage, and tree species. United Tree Care evaluates declining trees and provides an honest assessment of recovery potential.

How much does tree care cost?

Tree care costs vary based on services needed, tree size and number, and treatment complexity. United Tree Care provides free consultations and transparent pricing. Preventive care is generally less expensive than treating advanced problems.

What is plant health care?

Plant health care is an ongoing program of monitoring, preventive treatments, and maintenance that keeps trees healthy. United Tree Care offers customized programs with regular visits and treatments throughout the year.

Do you use organic treatments?

United Tree Care offers both conventional and organic treatment options when appropriate. We discuss treatment approaches with you and can accommodate preferences for organic or low-impact treatments.

How long does it take to see results from treatment?

Results timing depends on the treatment and problem. Some treatments show results within weeks, while others take a full growing season or longer. United Tree Care provides realistic expectations for treatment outcomes.

Can you help with tree selection and planting?

Yes. United Tree Care can recommend appropriate tree species for your location, assist with site selection, and provide planting services. Proper species selection and planting techniques are critical for long-term tree health.

Do you offer maintenance programs?

United Tree Care offers customized plant health care programs with regular visits, monitoring, and treatments. Programs are designed to meet your specific needs and provide consistent care throughout the year.
