The City of Alexandria is starting a new effort to manage invasive plant species at several locations throughout the city. The work will involve herbicide treatments and other control methods that vary by site and type of invasive species present. Signs with details about the treatments will be posted at each location, and some areas may have temporary fencing for safety.
The treatment schedule begins on Friday, October 10, at the Wilkes Street Tunnel between South Royal Street and South Fairfax Street. The focus here will be on removing invasive vines. Because native plants in this area are sensitive and the tunnel has historical significance, treated vegetation will be left to decay naturally rather than being removed right away.
In mid-October, crews will address broadleaf invasive trees, shrubs, and plants in Hensley Park at 4200 Eisenhower Avenue. The targeted forested area is east of the baseball field and divided into three sections. Species slated for treatment include Oriental bittersweet, Tree of heaven, Bush honeysuckle, Japanese honeysuckles, Multiflora rose, and Mimosa tree. Officials recommend that follow-up treatments continue annually for three years.
At Mount Jefferson Park (301 Hume Ave.), work will take place at the end of October as part of a multi-phase plan targeting Tree of heaven and English ivy first. Restoration efforts are planned after these initial steps. Because Tree of heaven can quickly regrow if cut down, multiple rounds of treatment may be needed with further evaluation 30 to 60 days after chemicals are applied. All actions will align with best practices set by the Urban Forestry team.
On Monday, November 24, Goat Hill Park (35 Kennedy St.) will see efforts focused on kudzu removal. Workers will cut kudzu near its base and treat it directly on the stump; vines won’t be pulled off trees but instead left to decay naturally to prevent harm.
Early in 2026—on a date yet to be determined—Four Mile Run Park’s kayak launch area is scheduled for similar management activities targeting Tree of heaven while maintaining clear sightlines along the boardwalk.
Future maintenance schedules call for continued invasive species control across Alexandria as needed.
