Enhancing, Restoring and
Protecting your Natural World

Exceptional tree care and fine gardening. It’s in our nature.

Les Arbres Certified Arborists and horticulturalists have been in the tree service and gardening business for over 45 years. Ours is a family-owned personalized tree service business. Where some firms have project managers who dispatch workers, the owners of our firm are on-site on every job, ensuring quality tree care, healthy gardens and landscaped plantings, and the long-term health, safety and beauty of the trees, shrubs, flowers and plants that adorn each property.

Discerning residential and commercial property owners who hire Les Arbres are making a decision to retain a family of experts with extensive academic training and decades of experience. The firm takes an artistic approach to design that reflects our deep abiding love of trees and plants. Leslie Lewis III, founder of Les Arbres, says “We’ve come to think of ourselves as custodians of nature. We zealously care for a discerning clientele who value our company’s knowledge, experience and commitment to customer service.”

Les Arbres offers Exceptional Tree Care and Fine Gardening services to discerning residential and commercial property owners in Greenwich, Darien, New Canaan, Ridgefield, Westport, Weston, Wilton and throughout Fairfield County, Connecticut. Our goal is to provide exceptional workmanship and personal service as arborists and horticulturalists to each of our clients. These comments come from a few of our satisfied clients.

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.
