A real Christmas tree needs to be kept in a location with plenty of sunlight, but away from direct heat sources. The tree should also be kept away from drafts and heaters, and watered regularly. Make sure the tree is well-hydrated, but not over-watered. If your tree starts to look dry, you can mist it with water using a spray bottle. Additionally, adding a bit of fertilizer to the water can help keep the tree healthy and vibrant. Finally, keep an eye out for signs of pests or disease, and treat them as soon as you notice them.
