To care for a real Christmas tree, make sure to provide it with plenty of water. The tree will need to be watered at least once a day, depending on how warm the room is. It's also important to keep it away from sources of heat, such as fireplaces or radiators. Additionally, keep the tree away from any potential hazards, such as pets or small children. Make sure to check the tree regularly for any signs of dryness or browning, and trim any dead or damaged branches as needed.
