Answer :
You should water your Christmas tree with cold water.
Hot water can damage the roots of the tree. The tree will be able to absorb the cold water more quickly, which helps it stay hydrated and healthy. Hot water can cause the tree’s roots to dry out, which will affect its lifespan. Cold water also helps keep the tree’s sap from rising, which can cause it to become brittle and dry. Cold water also helps limit the amount of air that gets into the tree, which can cause it to dry out faster. The colder the water, the better it will be for the tree. If you find that your tree is drying out faster than expected, you can add a few drops of lemon juice to the water to help keep it healthy.
