This year, as in the past, we'll see trees squatting on floors, desks, tables, and cabinets.
Dry ones are brittle and the needles pull out easily.
Stand your tree in a pail of water outdoors until you are ready to use it. Don't set up the tree near doors, stairways, in corridors or aisles, or near heat sources such as radiators and warmair ducts. Set them up where they're not likely to be knocked over. To give your tree proper support, use a tree stand - one that will hold water. Refill it daily.
