Mulchfest is a city-wide program through which you can recycle your Christmas trees to NYC parks to nourish their trees! If you want to participate in Mulchfest at Riverside Park, they will be having an event on Saturday, January 11th from 10am to 2pm (at 83rd Street across from River Run)! Signs will be posted at entrance of Riverside Park directing you to the appropriate location.
The Riverside Park Conservancy and the NYC Department of Parks & Recreation will turn your tree into mulch which will help fertilize the park throughout the year.
The city-wide event transforms thousands of holiday trees into pine mulch, which is used to blanket garden beds and tree pits throughout city parks.
If you want to volunteer, the parks need people to take lights off of trees before they get recycled.
Participants can take home a bag of mulch (which you can use to nourish the trees on your street during winter). And hot chocolate will be served. Learn more here.
