Hot, dry air will dehydrate your Christmas tree.
Don’t place it near a radiator, open fire, or in front of a sunny window. Choose a cooler, shady spot instead.
You can also try using LED fairy lights – these don’t get as hot as traditional incandescent bulbs. Plus they use a lot less electricity, making them cheaper to run.
The warmth and dryness of indoor air causes water to evaporate from needles at a rapid rate. Without a root system, trees can’t take in as much water and simply dries out, dropping its needles.
