Schlumbergera (Christmas Cactus) in a 17cm pot

Christmas cactus (Schlumbergera) have long, flat, segmented stems that look good all year round, but the real attraction is the vibrantly coloured flowers that appear at the ends of the branches in winter. They like a warm, bright position out of direct sunlight and not too much water - allow the surface of the compost to dry out between waterings. To get your Christmas cactus to flower every Christmas again, you’ll need to give them two rest periods during the year, one straight after flowering and another in September. To ‘rest’ your plant, simply put it in a cool room, ideally around 12°C and water very sparingly. Keep it there for about two months, then move it back to its original position.
