Cutting back a Christmas cactus (Schlumbergera bridgesii) is an important part of its care, as it encourages new growth and flowering. It should be done after the plant has finished blooming, typically in late winter or early spring.
To cut back a Christmas cactus, use a clean, sharp knife or shears to remove spent flower heads and any damaged or weak stems. You can also trim back healthy stems to encourage bushier growth. Be sure to make clean cuts at a 45-degree angle, and avoid cutting into the main stem of the plant.
