Montgomery county plants approximately 1800 trees per year to replace trees that have been removed from the public right-of way. Trees are replaced by the County on a request basis. If you desire a tree be planted in the right-of-way, you can request a street tree online using the link below or by calling the County’s 311 call center by dialing 3-1-1 (inside Montgomery County) or (240) 777-0311 (outside of Montgomery County). A County Arborist will inspect the property for appropriate species and location.
