Watering your Christmas tree is essential to keeping it healthy and vibrant throughout the holiday season. A good rule of thumb is to check the water level in your tree stand daily and add more water if needed. It's also important to use fresh water instead of tap water, as the minerals in tap water can cause build-up and clogging in the tree's roots. If you have a live tree, be sure to give it a thorough soaking once a week. With proper care, your Christmas tree can stay green and beautiful until the end of the season.
