Light and Temperature Christmas cacti need ample indirect light. They prefer a mild temperature, never cold, ideally ranging between 15 and 23 degrees Celsius. You can also keep them outdoors if you live in a region with mild winters. If you choose to do so, remember to bring them inside during colder periods and strictly avoid exposure to frost.
Watering Treat the Christmas cactus like a tropical plant: water it generously and allow the soil to completely dry between each watering. It’s crucial to let the soil dry to prevent root rot.
