When it comes to watering your Christmas tree, there are a few things you should know. First, make sure to keep the water level in the stand high enough to cover the base of the trunk, but not so high that it touches the branches. This will help keep the tree healthy and prevent it from drying out too quickly. Second, choose a water additive such as a tree preservative or a sugar solution to help keep the tree fresh and prevent needle loss. Finally, make sure to check the water level daily and add more as needed.
