Tree Services

  • Damage, disease or safety concerns can turn some trees from an asset into a liability. When this occurs, Davey’s certified and bonded arborists can be trusted for safe and efficient tree removal service in the Northwest, Seattle area.

    Look for these signs as an indicator it may be time to remove:

    • Heaving soil at the base of the trunk and beneath the canopy
    • Decay-producing fungi, such as mushrooms, growing at the base of the trunk
    • Chipped or peeling bark and cracks in the trunk
    • Cavities in the trunk or large scaffold branches
    • Dead or hanging branches in the upper crown
    • Fine twigs without living buds near the ends of branches
  • Tree trimming service is an important tool to help sustain a tree’s health and retain its natural appearance. Davey assesses your tree’s trimming needs from removal of unhealthy limbs to disease reduction.

    These signs can indicate when it’s time for professional tree trimming:

    • Your tree appears too close to power lines
    • Branches are close or are touching your home
    • You see dead, unsightly or loose hanging branches
    • Your trees have not been trimmed or pruned in the last three years
    • You would like your tree shaped for a more aesthetic curb appeal
  • Trees and shrubs in an urban setting loose nutrients in a number of ways, but applying fertilizer is a way to restore vitality.  Our slow-release fertilizer Arbor Green PRO® replaces nutrients and improves resistance to disease and stressful weather while maximizing the beauty of your trees and shrubs.

  • PHC is the best solution for maintaining your property’s trees over the long haul; it’s total health care for your trees. Our PHC program is designed for clients who are looking to save time, money and frustration by being proactive in the health of their trees and landscape.

    Some of our plant health care solutions include:

    • Air spade instruments to relieve soil compaction
    • Soil remediation technique
    • Supplemental nutrition
    • Supplemental irrigation
    • As well as other tree remediation tools

    Contact your local Davey arborist to find out how a PHC program can enhance the health and beauty of your landscape and trees all year round.

  • We rarely spray, but when the tent caterpillars are this bad, we trust you to do it correctly. Our arborist took the time to fully explain what the spray was and how it would affect insects, plants and songbirds. Please thank him for a job well done!

    Davey trimmed our hillside today. They climbed and worked tirelessly while being receptive and reactive to our requests. The trees needed major trimming, but also appealing pruning, and they accomplished this with care. Looking forward to recommending Davey & using them again in years to come.
