Christmas trees grow well in shade. However, heat dries out these trees quickly. If you have brought a tree home then you need to ensure that you keep it away from the fireplace, heat vents, direct sunlight, etc. You may wish to go as far as to lower the temperature of the room or use a specific humidifier to keep the air inside the home moist.
It is also observed that Christmas trees grown in containers are stronger and healthy than their counterparts grown in a normal routine. Those that are dug up and potted again can face trauma to their roots and may survive less. For the best results, these trees should be watered regularly but avoid overwatering these. Similarly, replanting a tree into the pot without roots is not a good idea.
