Tree Care

Our suite of tree care services will keep your trees healthy year-round.

Tree Planting

Strategic tree planting creates lasting value for your property. We’ll help you select species suited to your soil conditions, while also considering mature size, growth patterns, and seasonal characteristics.

We provide aftercare guidance for watering schedules, mulching, and pruning timelines.

Tree Fertilization

Trees need proper nutrition to stay healthy, resist disease, and maintain strong structure. We test your soil to identify nutrient deficiencies, then create a fertilization program specific to your trees.

Our deep-root fertilization can strengthen roots by delivering nutrients directly to root zones where they’re best absorbed.

Tree Health

Our specialists evaluate the structural integrity, disease presence, and environmental stress factors for your trees.

We’ll provide examinations of root systems, trunk stability, and canopy health to identify potential hazards before they threaten your property.

Tree Risk Assessment

If a towering tree could be threatening your property, we can conduct comprehensive tree risk assessments to identify potential hazards before they become problems.

We examine structural integrity, checking for decay, cracks, and weak branch attachments. Root systems are assessed for damage, disease, and soil compaction that compromises stability.

Each assessment considers the tree’s species, age, overall health condition, and surrounding environmental factors. You’ll receive detailed reports with recommendations for maintaining safety and tree health.

Tree Care FAQ

Trees in our region frequently face challenges from heavy rainfall, pests, and fungal diseases like root rot. Regular monitoring can help identify problems like cankers, dead limbs, or declining tree health before they become safety hazards.

Early intervention through proper pruning, disease treatment, or hazard assessment protects both your property and the long-term health of your trees.

We recommend having your trees professionally every few years, though more often evaulations might be necessary if your trees are at-risk. After storms, we’ll check for damage that isn’t visible from ground level but could pose safety risks.

Tree removal can be performed year-round, but late fall through early spring is often ideal when trees are dormant and have fewer leaves. Winter removals also minimize impact on surrounding landscape and allow better access to the tree structure for our crews.
