These can decimate a spruce at the very time you least expect it - the middle of winter. A better choice would be Douglas Fir, any of the true firs or the various pines, all of which are usually available in containers for the holiday season. Water Is Essential A six foot tall tree, common on today's market, can use three to four quarts of water the first day it is in the house. As a rule of thumb you will need almost a quart of water per day for each inch of diameter at the tree butt. All varieties of trees require about the same amount.
Tests indicate that the first days in a stand are most crucial to moisture uptake.
Studies have shown that a Douglas-fir tree without water will not last more than 10 to 14 days. With an adequate water supply, tree owners can expect to triple this. To prolong your trees's life, first if the tree has been cut for more than six hours, the butt must be re-cut prior to placing it into the stand. Second, the three stand must hold an adequate amount of water. Tests indicate at least a gallon capacity is required.
