Unless you're planning on lugging your Christmas tree out back and chopping it up for the fireplace, you're likely dumping it on the curb, leaving that 50-pound Fraser fir for the trash collection.But there's a better way.You can drop off your tree at several locations throughout the city on Jan. 7 and Jan. 14, for eventual recycling.Or, if you have a car, take it to one of six tree recycling centers around Philadelphia. Instead of withering away in a landfill, the tree can become mulch for gardens or provide nutrients for other plants.Just don't forget to remove all your ornaments and lights first.The sixStreets Department Sanitation Convenience Centers: 3901 Delaware Ave.; 5100 Grays Ave.; 2601 W.
