From the City of San Diego web site, here is information on Christmas Tree recycling..
Where can I recycle a Christmas tree?
- The Miramar Greenery accepts trees throughout the year.
- I Love a Clean San Diego and the County of San Diego have a website at www.WasteFreeSD.org to help County residents find the nearest tree recycling dropoff site in San Diego County.
- Curbside collection (For residents with yard waste collection only)
- Manual container customers using their own bins should place trees on the curb for collection on your regular greenery recycling pickup day. Trees over four feet in length should be cut in half.
