Underfloor heating can affect a real Christmas tree, in the sense that it will need to be watered more often than a tree not situated directly by a heating source.
Typically, a fir Christmas tree should be watered with a minimum of 500ml of water per day. However, bigger trees will require more, and it is recommended that those standing 6 feet tall or higher are subjected to 4 or 5 litres daily.
Essentially, real Christmas trees located in a space with underfloor heating will have to take in one or two more litres of water per day than they would in a room without, to prevent needles from dropping out quickly.
