Do a freshness test. Gently grasp a branch between your thumb and forefinger and pull it toward you. Very few needles should come off in your hand if the tree is fresh. Shake or bounce the tree on its stump. You should not see an excessive amount of green needles fall to the ground. Some loss of interior brown needles is normal and will occur over the lifetime of the tree.

Once you've chosen your tree, keep it in a sheltered, unheated area such as a porch or garage to protect it from the wind and sun until you are ready to decorate it.

Before you set up your tree, make a fresh, straight cut across the base of the trunk (about a quarter inch up from the original cut) and place the tree in a tree stand that holds a gallon of water or more. Warning: Keep the tree stand filled with water. A seal of dried sap will form over the cut stump in four to six hours if the water drops below the base of the tree, preventing the tree from absorbing water later when the tree stand is refilled. If a seal does form, another fresh cut will need to be made.

A tree will absorb as much as a gallon of water or more in the first 24 hours and one or more quarts a day thereafter. Water is important because it prevents the needles from drying and dropping off and the boughs from drooping. Water also keeps the tree fragrant.

In addition, keep your tree away from heat and draft sources like fireplaces, radiators and television sets. Test your light cords and connections before hanging them on the tree to make sure they're in good working order. You don't want to use cords with cracked insulation or broken or empty sockets. Also be sure to unplug the lights before you go to bed or leave the house. Never overload electrical circuits.

Sensible precautions such as these will help preserve the unique beauty and tradition that only a real Christmas tree can
