From Baltimore County:
The collection of live Christmas trees for recycling in Baltimore County will take place over a two-week period, beginning Monday, January 15, 2018. Because Christmas tree collection dates will vary from place to place, residents must have trees set out no later than Saturday, January 20 to ensure collection.
Pick-up Location Change for Residents with Alley Collection
New this year, residents should place trees out for pick-up at the same location where they would normally place trash and recycling for collection. Specifically, residents with alley collection are instructed to place their Christmas trees in the alley, where they normally set out trash and recycling. This change is in response to requests from the community and it improves operational efficiency. As usual, residents must follow these rules when placing their Christmas trees out to be recycled:
Only set out live (not artificial) trees.
Set out the tree only (no lights, decorations, tinsel, bags, tree stands, etc.).
Baltimore County collectors will pick up Christmas trees in standard trash/recycling trucks, and deliver them to County facilities to be chipped and later used as mulch. Baltimore County residents who live in an apartment or condominium should follow their property manager's rules when recycling their Christmas trees.
For a list of when your tree collection will occur visit the Baltimore County Trash Removal or residents who wish to drop off Christmas trees themselves may do so starting Tuesday, December 26, 2017. Christmas trees (no lights, decorations, tinsel, bags, tree stands, etc.) may be taken to any one of the County's three drop-off locations. For directions to the County's drop-off centers, residents may visit the Bureau of Solid Waste Management website or call 410-887-2000.
