Fairy Castle Cactus
Fairy Castle Cactus Acanthocereus tetragonus ‘Fairy Castles’ (Fairy Castle Cactus) is a dwarf, columnar, branching, slow growing cactus with spiny, five-sided, mid-green stems producing numerous smaller offsets. It will reach about 6 feet (1.8 m) tall with great age. Nocturnal, white or yellow flowers are rarely produced.
USDA hardiness zone 10a to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Like most cacti, Cereus are fairly low-maintenance and hardy. Make sure they receive enough water without becoming waterlogged, especially during the summer, and fertilize them for best results. If the roots have become black or overly soft, the cactus could be experiencing root rot – cut away the affected parts and replant. Like all cacti, give them lots of direct sunlight, especially during the summer. Well-drained soil is best, and most Cereus perform well in a soil that contains some organic material. Some recommend avoiding a soil that contains sphagnum moss, though – it can make the cactus vulnerable to root rot.
Cereus cacti propagate quite easily from cuttings; simply sever a branch and replant in moist, well-drained soil. It helps to allow the cut end dry out and harden before you replant it; this makes it easier for the new cactus to form roots.
It may become necessary to repot your Cereus if it outgrows its container. If so, make sure the soil is dry and then remove the pot. Knock away old soil and prune away any rotted or dead roots, then replace it in a new pot and backfill with new soil… –
