Cut off about two inches of the tree trunk at an angle to expose fresh wood for better water absorption. Water the tree every day. An average tree may consume between a quart and a gallon of water per day. If the water level drops below the cut end of the tree, a seal will form on the cut and the tree will not be able to absorb any more water. Keep the tree away from all sources of heat to preserve its freshness.
Miniature lights are a better decoration choice than standard sized lights.
The cooler miniature lights do not dry the tree needles as quickly. When the needles get brittle or dull and begin to fall from the tree, it is time for the tree to go back outside. Check every set of lights for broken or cracked sockets, frayed or bare wires, and loose connections before using. Throw away anything that is not in perfect condition. Never use electric lights on a metallic tree.
