Q: I’ve noticed that my Christmas tree, which we cut at a farm, drinks almost a gallon of water every day. Does it drink that much water from the ground when it’s growing normally or is its thirst an effect of cutting it and bringing it inside?

A: It’s true: a small evergreen tree needs a gallon or more of water each day, depending on its size and the weather. Freshly cut trees like yours could be expected to absorb a gallon each day. The amount will taper off as the upper part of the tree realizes that its roots are gone. In the meantime, check the reservoir level each day so water is always available to keep the needles fresh.
