Old City Green in Washington DC has volunteered to help you get rid of your Christmas Trees after the Season. You can return them and they in turn will compost. Here is the email I received:
Just wanted to let you know that if one bought a Christmas tree
(A farmed tree) from us they can return it and we will turn it into compost.
It is better than sending a tree to a land fill.
We have 4 composting bins at OLD CITY green
