Keeping a Christmas tree alive for longer requires some basic care and maintenance. Make sure to keep the tree watered regularly, as dry conditions can cause the needles to fall off prematurely. Trim the ends of the branches to help the tree absorb water more effectively, and avoid placing the tree near heat sources, such as fireplaces or vents. Additionally, providing a regular fertilization regimen can help nourish the tree and keep it healthy. Finally, make sure to keep the tree away from pets and children who may be tempted to touch or pull on the branches, which can also cause damage.
