About fifteen new street trees will be planted on Beacon Hill this spring as part of the city’s efforts to expand its urban forestry.

The coming trees are spread throughout the neighborhood with slight concentrations on the Nashua Street side of West End Park and along Staniford and Causeway Streets.

The Boston Parks and Recreation Department’s Urban Forestry Division (BPR) said in a statement that the trees are part of a plan to bring 1,200 new trees to Boston citywide. New trees will be planted between mid-April and the end of June.

There are less trees coming to Beacon Hill this year compared to last year, when 55 trees were planted in the neighborhood by the BPR. According to a spokesperson for the Urban Forestry Division, “While the number of trees planted in Beacon Hill is lower than last year, this reflects the neighborhood’s limited space for new tree pits in the public right of way and our policy of replanting where trees have been removed.”

The surge of tree canopy coverage in 2024 was made possible by the department’s greater capacity to evaluate and replace dying trees last year. Of the 55 trees planted last year, several did not survive but were replaced under warranty in the fall.

The BPR works with a contracted vendor to install all trees, and each comes with a two-year warranty. Under the terms of the warranty, the contractor is required to water the trees during the growing season for the entire two-year period. However, the BPR is asking residents to help support the young trees by following the Tree Care Tips posted on the Parks Department’s website.

Residents are especially urged to assist in watering trees during hot, dry spells and to prevent pet waste from accumulating near tree pits, emphasizing the reminder, “Don’t mark the bark.”

To assist in watering trees, the department website includes instructions on how to fill the plastic watering bags that residents should see wrapped around the base of newly planted trees. For trees with a single watering bag, they should be filled completely once a week by pouring water into the opening at the top of the bag, opposite the zipper.

Although the neighborhood’s available planting space is limited, Beacon Hill’s mature trees remain a crucial part of the area’s historic character and bring many crucial benefits to the neighborhood. Boston’s Urban Forestry plan refers to trees as “the only infrastructure that grows stronger and more effective with age.”

Higher tree canopy coverage is associated with many benefits, including decreasing maximum temperatures at street level and reducing flooding and air pollution.
