Trees in Watertown

Street trees provide many benefits for residents and for the environment. They help reduce surface temperatures and create shade, beautify our streets, and contribute to health benefits associated with increased greenery, such as improved air quality and carbon dioxide absorption. 

Street trees have also been found to increase property values, help filter stormwater run-off, and reduce flooding through increased water absorption. They can even contribute to public safety, as trees along roadways often encourage drivers to slow down. A full map of Watertown's street trees with species information is available online.

Request a new public shade tree

Residents can request that a new public shade tree be installed by filling out the New Tree Request Form. When you fill out the form, the Tree Warden will review the application and assess whether the site is suitable for a public shade tree, and if so, what type of tree would best fit the environment. 

Caring for public shade trees

If a public shade tree is installed in front of your residence, you will be asked to help care for it. As a homeowner, here’s what you should do:  

  • Water newly planted trees. If you see watering bags attached to the tree, fill them up! Otherwise, water at the base of the tree for 30 minutes with a slow trickle of water. New trees need about 20 gallons of water per week during the growing season (April-October) for two years after planting. Watering is not necessary during the winter. 
  • Avoid parking on unpaved surfaces around the tree. Parking can compact tree roots and eventually harm or kill the tree.
  • Refresh mulch around the tree. Newly planted trees will be mulched to help retain moisture and fight competing weeds. If replacing mulch, please use organic products and place material around the tree in a 2-3" layer. Do not mound the mulch around the trunk of the tree.  
  • Please do not fertilize or prune the tree. If you have concerns about tree health, contact the Tree Warden. Improper pruning or overfertilization can harm or kill the tree. 
  • Do not plant other woody shrubs near the tree. Flowers/grasses are generally okay, but woody plants can compete with the tree for nutrients and water.
