The program establishes drop-off sites around the city for residents who don't have curbside refuse pickup service.
According to the city's Environmental Services Department, people who drop off their trees should make sure they don't contain ornaments, lights or stands. No plastic bags, trash or trees used for commercial or fundraising purposes are allowed.
The program diverted around 1,100 tons of holiday trees from the Miramar Landfill last year, the equivalent of more than 140,000 individual Christmas trees.
San Diego residents can recycle their Christmas trees at the Mirarmar Landfill Greenery at 5180 Convoy St., off Highway 52.
