This weekend is the last chance New Yorkers have to drop off their Christmas trees at various mulching locations in the five boroughs. 

There are 72 locations where trees are placed in a chipper and transformed into mulch. Volunteers also pick up trees from various neighborhoods. The mulch is then dispersed throughout parks and visitors can also take a bag of mulch if they want to.  

The NYC Parks Department says that mulching trees benefits the environment in a number of ways such as deterring weeds, retaining moisture and keeping roots warm.
