To keep a Christmas tree alive and healthy, there are several things you can do:
1. Choose the right tree: Select a fresh, well-watered tree with pliable branches that are not shedding needles.
2. Prune the tree: Before bringing the tree inside, cut off the lower branches and make a fresh cut at the base of the trunk.
3. Provide proper hydration: Place the tree in a stand with a water reservoir and keep the reservoir filled with water.
4. Maintain proper temperature: Keep the tree away from heat sources like radiators and fireplaces.
