Warm Weather Begins Early Gingko Spray
Urban Forestry Will Start Spraying Thursday, April 8
(Washington, D.C.) Unseasonably warm weather has brought the first signs of the unsavory female ginkgo fruit to life much earlier than expected. To prevent the notoriously unpleasant odor of this popular tree from overtaking city streets, the District Department of Transportation’s Urban Forestry Administration (UFA) will start spraying these fruits tomorrow, Thursday, April 8.
Spraying will begin in Wards 1, 2 and 6, where female ginkgo trees are most prevalent, and continue through Wards 4, 3, 7, 8 and 5. The spraying will be conducted at night and there is no need to move vehicles parked on streets.
The specific spraying locations will be sent to the ANC commissioners and are available upon request. If residents have any questions about the spraying, they can contact the Urban Forestry Administration at (202) 671-5133.
The mission of the Urban Forestry Administration is to establish a full population of street trees within the District and to ensure that those street trees are maintained in a healthy and safe condition. UFA has 19 certified arborists on staff who are responsible for issuing permits, enforcing regulations, and caring for approximately 140,000 trees throughout the city.
