On Saturday, Jan. 12, or Sunday, Jan. 13, 10 am to 2 pm, bring your tree to the 3rd Street entrance of Prospect Park or the Park Circle entrance at Parkside Avenue and Prospect Park Southwest, and it will be turned into environment-friendly ground topping. You can take home free mulch for your own garden. Can’t make it? If you live in the area bounded by Union Street, 6th Avenue, 15th Street, and Prospect Park West, you can leave your tree at either end of your block before 11 am on both days, and volunteers from 1-800 Mr. Rubbish will pick it up.
