Is there anything I should add to the water to keep the Christmas tree fresher longer?
There are many additives on the market that are supposed to help keep the tree fresh. However research has shown that just plain water is really all that is needed. Before placing the tree in its stand you should cut about an inch off the trunk base and then place that fresh cut into the plain tap water in the stand. If you forget to water it and the water is completely gone, then you will need to make a fresh cut to keep the trees ability to take up water in effect. Once the base dries out, resins form that stop the uptake of water kind of like a wound healing over.
