If I had things my way, that beacon of holiday cheer that is the Christmas tree would live rent-free in my house until it looked like this:
At which point I would then pass it off to Charlie and Snoopy who would chill with it for a while and then do the eco-conscious thing by dragging it to the nearest composting center. Doing so not only benefits the environment, but also your mental health as I think Seasonal Affective Disorder is probably aggravated by the sight of lonely Christmas trees slumped on the curb waiting to be picked up by the garbageman.
When taking your tree to be composted just make sure to weed out all that shiny tinsel and don’t forget to take all the ornaments off too! There are a lot of convenient drop-off locations for trees in Philly including the Sanitation Center at 3033 South 63rd Street. The Philly Streets Department has got it together.
