Watering a Christmas tree is an essential part of keeping it healthy and vibrant throughout the holiday season. The frequency of watering can vary depending on the type of tree, the environment, and the amount of time it's exposed to indoor heat. As a general rule, you should aim to water your tree daily or every other day. The key is to keep the soil moist but not too wet. You can also mist the tree with water daily to help keep it hydrated. Remember to keep the tree away from direct heat sources like radiators or fireplaces as this can dry it out. Happy holidays!
