If haven't gotten rid of your Christmas tree yet, there are two options left until Jan. 31. If you receive city yard trimmings collection service, the city will pick trees up on regular collection days until month's end. Trees must be set out on their own, one meter clear of carts and laid on their sides. Remove decorations and tinsel. Alternatively, you can drop trees off at the Â鶹´«Ã½Ó³»south Transfer Station or the Â鶹´«Ã½Ó³»landfill at no charge up to Jan. 31.
