Fairy Castle cactus (Acanthocereus Tetragonus) is a cacti grown in North America. So why it is called 'fairy castle cactus'? It is because of hundreds (or even thousands) of green stems that clump together and resemble a spire like a castle.
In case you wonder how to propagate castle cactus, I made a video on what I do to successfully produce miniature baby fairy castle cacti. Just always use a sterile scissor/shear because this cactus is prone to rot if not conscious about it.
The process of fairy castle cactus propagation begins with selecting stems, followed by cutting. Simply follow the steps I made and for sure, you'll have a bountiful fairy castle cactus plants.
