The Cereus Fairy Castle Cactus is the colorful name by which the plant is marketed and refers to the numerous vertical stems of different heights that resemble spires and turrets. The fairy castle cactus rarely blooms. Cacti need perfect growing conditions to produce flowers and the plants in the Cereus family bloom at night. Fairy castle cactus flowers are large and white and usually will not occur until the plant is ten years old or more. If your cactus comes with a flower, examine it carefully. It is likely a fake bloom used as a marketing ploy (these are also typically yellow rather than white). There is no need to remove the fake fairy castle cactus flower, as it will fall off by itself eventually.
Planting & Caring –
Fairy castle cactus is a full sun plant that requires well-drained soil. Plant the cactus in an unglazed clay pot that allows excess moisture to evaporate. The fairy castle cactus plant will grow best in a good cactus potting soil or you can make your own. Mix one part potting soil with one part each of sand and perlite. This will make a good gritty medium for the cactus.
