A Tree is a Recycling Machine

When a tree is healthy, all parts of the tree — the roots, stem and leaves — function at optimal efficiency.

  • The roots provide nutrients. They “breathe” in order to provide nutrients via osmosis.
  • The tree stem houses the vascular system that translocate nutrients and food throughout the tree.
  • The leaves produce food in the form of sugars and starches using photosynthesis.

If any part of this triad is impaired, a tree may show signs of distress or decline. Les Arbres’ arborists identify the underlying causes of distress and take steps to insure that the tree is functioning at maximum efficiency.


Tree Care as a Fine Art

The arborists and tree care experts at Les Arbres aim to respect both the functional and aesthetic value of each tree, shrub and herbaceous plant we care for. We are experts with decades of practical experience as certified arborists and horticulturalists.

Beneath our technical and scientific work lies an artist’s deep abiding love of trees and plants. We combine experienced tree service, garden design and landscape design with extensive scientific knowledge. We create specific designs and long-term care plans for each property entrusted to our care.
