"A city grows great when people plant trees under which
they know they will never sit." ~ proverb

Water, Water, Water!

Hot, dry Seattle summers are stressful for young trees. To ensure your tree thrives this summer, be sure to water regularly once-twice a week for the first 3-5 years after the tree is planted.

Roots will follow the water. Make sure to water deeply so that roots don’t rise to the surface and crack surrounding sidewalks or driveways. Water using gator bags placed around the trunk of the tree or place a hose at the base of the tree and allow a slow trickle for 30 minutes.

Seattle's Updated Canopy Cover Analysis

The City of Seattle recently undertook a project to estimate canopy levels in 2002/03 and 2007 using more rigorous methods than were used previously. This new study finds Seattle to have about 23% canopy cover. The data from the recent study is exciting because it provides critical information about recent canopy changes across the city as well as within different land uses, neighborhoods, and watersheds. This information will allow the City to better plan and manage Seattle's urban forest.

Read the report on the effects trees have on business. (pdf)

Shoppers will spend more in stores surrounded by trees than they will for identical items in stores without trees. Shoppers will also travel farther, stay longer, and visit more often when stores are surrounded by trees.

Q: What is a certified arborist? What services do they provide, and how can I find one to hire?

A: Certified arborists are trained tree professionals licensed by the International Society of Arboriculture. Certified arborists must pass an extensive test and have at least three years of professional experience as well as ongoing education. Not all those who advertise as being tree care professionals are certified arborists – make sure you hire one who is.

Arborists can prune trees of all sizes, inspect and treat trees for pests and diseases, and safely remove dead or unsafe trees. Arborists can also plant trees, provide emergency tree care, remove stumps, and address issues such as fertilization. More information on the services an arborist can provide can be found here.

Certified arborists in the Seattle area can be found through the International Society of Arboriculture. More information on how to hire an arborist can be found here.

One caution: a quality arborist will never recommend the “topping” of a tree. This is thepractice of cutting off the central leader, or main trunk, of the tree at any height. This is an extremely hazardous practice that could make your tree less safe, more costly to maintain, and eventually kill the tree.
