Holiday cacti, such as the Thanksgiving cactus and Christmas cactus, are long-lived and easy to care for plants. Despite being very similar, there are subtle differences between the two. The Thanksgiving cactus has pointy edged stems, while the Christmas cactus has rounded, scalloped edges. Additionally, their flowers have different shapes. Both types of cacti can bloom close to their respective holidays and require the same care. They enjoy bright, indirect light, well-drained soil, and regular feeding. These cacti can be easily propagated by taking cuttings. They are also safe for pets. To encourage blooming, provide the cacti with a certain number of hours of darkness and cool nighttime temperatures.
