What's That Tree?

It's a common question for us here at Seattle reLeaf, especially in the spring when flowers and leaves start to emerge. Now there's a new way for you to find the answer. Tree Walk - Seattle is an Android-based app with a web version for non-Android users that can help you identify the beautiful trees you see around you in Seattle everyday. Learn more here.


Street Tree Manual Available

Seattle Department of Transportation (SDOT) has just released a new resource to provide a one-stop tree care reference for residents, developers, contractors, and tree service providers. The manual outlines the requirements and standards established in the 2013 Street Tree Ordinance. Click this link to open and explore the new manual.

If you have questions about the manual, contact SDOT at (206) 684-TREE or


Stop Tree Topping

If your trees are being pruned, be sure they are not being topped. Tree topping is an outdated pruning practice that indiscriminately removes large amounts of leaves and branches. It looks terrible, causes serious damage to the tree, and often turns a safe tree into a safety hazard. Check out this great resource from the City of Tacoma on why tree topping is a terrible way to treat your tree. If you are hiring someone to prune your trees, make sure they are an ISA Certified Arborist. A legitimate arborist will never recommend tree topping.
