Christmas cacti are certainly among the least understood of houseplants. They have a bad reputation for being difficult to get to flower, or for flowering at the wrong time.
However, once their secret is discovered, these wonderful plants will produce colorful flowers every year.
Although it's a succulent, the Christmas cactus's care is more reminiscent of a tropical plant. Native to Brazil, it grows in humid, tropical undergrowth.
Light and temperature
Christmas cacti need plenty of indirect light. They prefer a mild, never cold, temperature, ideally between 15 and 23 degrees Celsius.
You can also keep it outdoors if you live in an area with mild winters. If you decide to do this, remember to bring it inside during the coldest periods and avoid exposure to frost at all costs.
