Our arborists are balancing plant health, safety and artistry when pruning and shaping your plants from specimen shrubs or prized lace leaf maples to the largest shade and evergreen trees. We prune to emphasize a tree's natural shape. If the tree has structural problems, we can cable it to increase its safety.

The Arbor Advisor
Report
In the Willamette Valley, our most common deciduous native tree is the bigleaf maple. It gets its name from the size of its leaves. In Latin, the species name Acer macrophyllum means big leaf: macro meaning large and phyllum meaning leaf. The bigleaf maple has the largest leaf of any maple in the world, measuring 6-12 inches across and having five lobes, resembling a human hand.
