When caring for your Christmas cactus, be sure to keep it in bright, indirect light and water it regularly but allow it to dry out in between. Use a well-draining potting mix and fertilize it once a month during the growing season. Protect it from cold drafts and temperatures below 50 degrees Fahrenheit. Make sure to repot it every 2-3 years to ensure it has enough space for its roots to grow. With proper care, your Christmas cactus will thrive and produce beautiful blooms.
