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 Long Island, NY.

    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. Contact your local Davey arborist today for a free consultation for tree trimming services in Long Island, NY. 

    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

    Contact your local Davey arborist for a free consultation for tree trimming services in Long Island, NY.

  • 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.

  • Plant Health Care 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 techniques
    • Supplemental nutrition
    • Supplemental irrigation
    • As well as other tree remediation tools

    Contact your Davey arborist for more information on how a PHC program can help you reach your property goals.

  • Tree Planting: Planting a tree that will thrive depends on the landscape, the climate and property goals. Our certified long island arborists provide expertise on “right tree, right place” – what trees to plant and where and how to plant them.

    Cabling & Bracing: Our arborists pinpoint weak limbs that need cables and braces to reduce potential risk.  Professional installation strengthens weak branches and reduces tree stress caused by weather elements and heavy foliage.

    Tree Risk Assessment: Schedule seasonal tree risk assessments to keep your trees and home safe. Certified arborists can identify safety hazards and potential weaknesses earlier. Catching problems early is far cheaper and safer than treating advanced problems later.

    Lightning Protection: Our tree protection system uses heavy gauge copper cables to divert damaging lightning safely away from your beloved tree into a buried ground rod. Our system also includes a fuse that monitors the tree for lightning strikes and will alert us if the tree has been hit. 

    Shrub Pruning: Have a Davey arborist prune your shrubs to keep them shapely while also allowing more light onto the shrub. The result? Healthy shrubs with denser foliage that look better than ever. 

Lawn Services

  • Our experts take the guesswork out of fertilization by assessing key components such as the right percentage of nitrogen, phosphate and potassium needed and the amount of applications required to maximize the health and vibrancy of your unique lawn and landscape.

  • Davey Tree’s lawn aeration service breaks up the interface, or overlap of different soil types or sod, and promotes positive conditions for turfgrass growth and development. The process helps air and water penetrate deep into the soil, which encourages deeper root growth and better turf quality.

  • Your Davey lawn technician will routinely inspect your turf and soil to identify signs of a potential grub, insect or pest infestation. If an infestation has occurred, your Davey technician will develop a customized grub control and pest management plan that will be most effective in ridding the infestation from your unique lawn.
