This year's MulchFest is a record breaker.
The Parks Department says that more than 30,000 trees were turned into wood chips.
The program was in effect in all five boroughs, with mulching sites in more than 80 locations.
Manhattan residents had the highest turnout, with nearly 12,000 trees recycled in the borough.
Brooklyn came in second, with more 9,000 trees.
The mulch will be used to nourish parks throughout the city.
