Real Tree Care. 
A few simple care tips will enhance the enjoyment of your Christmas tree and keep it fresh and fragrant throughout the holiday season. When you bring the tree home, cut one-quarter inch off the base of the trunk. Keep the tree outdoors, standing in a container of water, protected from the wind and sun until you are ready to decorate. This will help the tree retain its moisture.

Before bringing the tree into your home and placing it in a stand, make a fresh cut a minimum of a half-inch to one inch off the base of the trunk. This opens the tree stem so it can take up water. Immediately place your tree in the stand and fill it with fresh water. If you allow the water level to drop below the fresh cut, a new seal will form over the stem.

Remember, trees are very thirsty. They may drink between 2 pints to a gallon of water a day. Use a water-bearing stand with a capacity of a gallon or more. Check the stand daily and supply fresh water as needed.
