We’ve already noted Mulfchfest, which will take place next weekend, but the Sanitation Department will also be recycling trees left at curbside. Here’s a bit from their email:

Sanitation Commissioner John J. Doherty announced that the Department will begin its annual Christmas tree curbside collection and recycling program on Monday, January 5, 2009. The program will run through Friday, January 16th. Residents should remove all tree stands, tinsel, lights, and ornaments from holiday trees before they are put out at curbside for removal. Trees must not be placed into plastic bags. Clean, non-bagged Christmas trees that are left at the curb between Monday, January 5th and Friday, January 16th will be collected, chipped, and made into compost. The compost will be processed and subsequently spread upon parks, ball fields, and community gardens throughout the city. In January 2008, the Department collected over 160,000 discarded Christmas trees.

The Parks & Recreation Department will be hosting Mulchfest 2009 on Saturday, January 10th and Sunday, January 11th from 10 A.M. to 2 P.M. at more than 80 sites throughout the city. To find citywide locations, visit the Parks & Recreation website at www.nyc.gov/parks. The citywide service
allows New Yorkers to drop off their holiday trees at designated parks for mulching and event attendees can pick up free mulch. All lights, ornaments, and decorations must be removed from the trees prior to drop-off.

And so, the holiday season officially ends until Labor Day.
