Seattle ~ London Plane pruning

Tree Harmony Arborist pruned a large and over extended London Plane tree recently.   This was critical to the health and safety of the tree, as well as the properties below.   We set this fine tree on a good course.    Good pruning makes a huge difference!

Seattle ~ Georgetown Landscape Transplant

Tree Harmony worked with Jamel to transplant a dozen Emerald Green Arborvitae from the rear landscape to the front, to furnish screening to the right of way.   Our crew removed the rear trees and moved and planted them in a beautiful pattern to the front.  This was an extensive project moving quite heavy trees, lasting 2 full days with a large crew.  We also built an irrigation system with dedicated drip watering to each tree.   We ran that under the sidewalk and sourced it to the home water supply. To plant the 20 trees, we hauled an extensive quantity of compost.   This was a privilege working with Jamel to protect and enchance his trees.    We plan to prune them when they fill out, to maintain proper structure and health.

Western Red Cedar ~ Beacon Hill, Seattle

Last month we pruned a large cedar on a small, tight lot in Seattle.    We  thinned the crown of deadwood and crowded and unhealthy branches.    We lifted the canopy from the floor and cleared it from the sidewalk and home.    This cedar is on a good path with periodic pruning to remove dead and contain the structure.

Seattle Tree Pruning

We completed a comprehensive tree pruning project last month for a new client in Loyal Heights in Ballard.    We worked on several dozen trees, including Japanese Maples, ornamental maple and dogwood, ewe, stewartia, bay laurel, and andromeda.   The project encompassed a full day with our crew.   We set the trees on a proper pruning cycle, furnish proper clearance from the home, and enhanced our client's tree health.

Regular and consistent pruning of trees in urbanized areas brings numerous benefits. It enhances their lifespan, boosts their resistance against diseases and decline, increases their value, and allows owners to relish their beauty while ensuring safety. Restorative pruning plays a vital role in rectifying improper pruning, addressing damage caused by natural factors or diseases, and guiding trees towards healthy growth. Whether pruning for aesthetic purposes, clearance, or to allow filtered sunlight, it is possible to achieve these objectives without compromising the tree's overall health and vitality.
