how much water does a christmas tree need

Christmas trees typically require about one quart of water per inch of stem diameter. For example, a six-foot tree with a five-inch diameter would require approximately 10 quarts of water. It is important to keep the water level in the tree stand above the base of the trunk, and to check the water level regularly. Additionally, it is recommended to cut the trunk of the tree a few inches off the bottom before putting it in the stand, to allow for maximum absorption of water.
