1. Select a fresh tree.
A dry tree is a major fire hazard; to get the freshest tree, cut it yourself. If you purchase a precut tree, run your hand down a branch to make sure it is not dry and shedding needles. Test the tree by bending a needle: If it snaps, the tree is too dry.
2. Leave the tree in a bucket of water overnight.
Place the tree in the stand the next day. Water it daily.
3. Place the tree at least three feet away from a fireplace, radiator, or other heat source.
4. Unplug tree lights when not in use.
Do not leave the lights on during the day, when you go to bed, or when you leave the house.
5. Do not place lit candles on or near a tree.
If tradition requires candles, use specially weighted sconces that do not tip over. Do not add electric tree lights or other electric equipment to or around the tree (such as a train set), in the event that water must be thrown onto the tree. Do not leave the tree unattended.
