Long Island Local Tree Services

  • Damage, disease or safety concerns can turn some trees from an asset into a liability. When this occurs, Davey’s bonded and ISA Certified 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 a tree:

    • 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

    Call 631.956.5001 to make a tree removal appointment.

    • 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

  • 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.

  • 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.

  • 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.

    Call 631.956.5001 to learn how lawn aeration can benefit your landscape.

  • Your crew which was led by your expert tree cutter Charles was absolutely outstanding. They were extremely professional, precise, clean and safe most importantly. They remained in communication with me while my extremely large tree was taken down behind my home. Charles is extremely knowledgeable and is an asset to your company! I will definitely come back to your company if I ever need you in the future. Thank you for everything! -Sarah
