Tips for keeping Christmas trees fresh
Select a fresh tree with good color and firm, flexible needles that do not easily pull from the branches.
Place the tree in plain water immediately after recutting the trunk at least one-half inch above the old cut. The container you use for your tree should hold 2 to 4 quarts of water.
The longer you wait to place your tree in water, the greater the chances are that it will lose the required moisture content to keep it fresh through the holiday season.
Never place your tree on a wooden stand.
Locate the tree away from sources of heat. Avoid placing the tree near heaters, wood toves, fireplaces, large appliances such as TVs, and direct sunlight.
Be careful not to block a door or other exit with the tree or rearranged furniture.
Use mini-lights on your tree and never place candles on or near your tree. Remove your Christmas tree as soon as possible after the holiday. Never burn your Christmas tree or wrap-ping paper in the fireplace. The rapid burning and excessive heat can damage the firebox and chimney, creating a serious fire hazard.
