Why Hire an Arborist?

Do you understand the difference between a landscaper and an arborist? The green industry can be confusing. There is a lot of overlap between landcape companies and tree companies. Landscapers offer lawn and garden care. They can give basic tree advice.

An arborist is an individual who is trained in the art and science of planting, caring for, and maintaining trees and shrubs. Arborists understand how trees integrate into the landscape and around buildings. Arborists are trained in pests and disease that affect your trees. Arborists can care for your trees regardless of their size, climbing to the tops of even very large trees to prune and maintain them.

The certifications you should look for are those of the International Society of Arboriculture. Founded in 1924, the ISA promotes the professional practice of arboriculture and fosters a greater public awareness of the benefits of trees. Certified arborists are issued a certification number which can be verified at the ISA website. You should also watch for these logos when hiring:


How Do I Recognize Good Tree Maintenance?

Some basic things to watch for include:

Young Tree Training - Have your trees properly pruned when they are young. This will result in less need for corrective pruning as they mature.

Spurless Climbing - Except for removals, trees should never be climbed with spurs. Spurs damage the tree by creating wounds, entrance points for pests and disease.

No Topping - Topping is a temporary and ineffective solution that actually makes a tree more hazardous in the long run.

Form - Pruning should not alter the natural form of the tree. A professional should know how to obtain objectives without compromising the aesthetics of the tree.

25% Rule - Minimize excessive regrowth and stress to the tree by only removing up to 25% of the canopy.

Poor pruning can cause damage that lasts for the life of the tree. Take the time to find a tree company that respects your trees.
