General Pruning​

Removal of dead, diseased, weakly attached, and broken branches. This process defines the tree and closes entry points for pests and disease.

Retrenchment Pruning​

Safely reduces the height and spread of mature trees, enhancing their health and longevity and mitigating potential risks; this careful process also helps preserve the tree’s natural form while preventing possible hazards.

Crown Thinning

Select branch removal for light and air penetration in addition to a reduction in sail area of the tree. You can improve light in your yard without removal and reduce susceptibility to storm damage.

Vista Pruning

Create a view without removing trees. We have years of experience improving views in the San Juans, one branch at a time. Let’s see what we can do for your view.

Crown Restoration

Improve the structure of a tree by highlighting proper scaffold branches and guiding the tree to take on a natural, healthy form. This is often used to correct improper pruning.


When it is necessary to remove a tree it must be done with precision and with all safeguards in place

Hazard Trees: For trees that may inflict injury or damage to property, advanced rigging techniques are employed to safely bring down a precariously positioned tree.


We specialize in restoration and maintenance of new and heritage orchards.

We pay special attention to sculpting fruit and nut trees

Complete cleanup services including chipping and greenwaste disposal

Forest health care and restoration

Clear cutting in the San Juan Islands has left us with returning 2nd and 3rd growth forests

Now, while they are developing, it is crucial to assist our forests so that they return to their beautiful and stable environment.

Tree Health Care

Assess and implement the health care needs of specimen trees

  • Fertilization to reinvigorate a declining tree that cannot be helped by pruning alone
  • Diagnose diseases and inorganic stresses that may inhibit health and future growth

Site development/ pre-construction assessment

It is our goal to assist in the preservation of existing trees on a developing property.

It is important to assess their environmental needs before, during, and after construction to avoid tree failure
