Disposing of Holiday Trees & Refuse Christmas trees will be picked up without a refuse sticker if placed at the curb on your regular refuse collection day during the first and second week in January. After that, a sticker is required. All ornaments, lights, tinsel, and nails must be removed. Trees may not be placed in plastic bags. Wrapping paper, packing peanuts, garlands, and wreaths may be included with regular refuse. Boxes may be recycled if they measure no more than three feet by three feet, have been flattened, and bagged or bundled.
