Watering your Christmas tree is an important part of maintaining its health and keeping it looking its best. You should make sure to water your tree every day, but be careful not to over-water it. Water your tree in the morning, and make sure to allow the water to soak into the soil before you water it again. If you notice the soil is dry, give it a good soaking. If you're using an artificial tree, you won't have to worry about watering it, but you'll still need to dust it regularly.
