Join the New York City Department of Parks & Recreation, the New York City Department of Sanitation , and GreeNYC  to recycle your Christmas trees into wood chips. These wood chips are used to nourish trees and plants on streets and gardens citywide. Or, take home your very own bag of mulch to use in your backyard or to make a winter bed for a street tree . More than 30,000 trees were recycled last year. Help us top this number!
