It has 1 inch long, grey areoles and stems that are up to 8 inches tall that are dark green.

There are five sides to each stem, and along the ribs on each side are short white spines.

The plant’s areoles have one or two 1.5-inch-long spires that are white or yellow in hue.

If the cactus is already covered with blooms, pay close attention because they can be fake.

These succulent plants prefer the full light and thrive in a bright, sunny environment far from air conditioning or rain.

These consist of regions with average annual temperatures between 25 and 50 degrees Fahrenheit (-4 to 10 C).

The fairy castle cactus needs the same amount of water as other succulents because it is one.

Before watering again after letting the soil entirely dry up, the water must drain out of the drainage hole.

‘Fairy Castle’ Acanthocereus Tetragonus thrives in well-drained soil or cactus potting soil.

Sand, perlite, and houseplant potting soil can be combined to create your own potting medium. As a result, the cactus grows in a grainy media.

When a fairy castle outgrows its current location, it should ideally be moved.

For the development of its roots, the plant needs a lot of room. Repotting should therefore be done every other year or whenever the plant outgrows its container.

Grooming and Maintenance

An excellent choice is an unglazed clay pot since it allows the unwanted excess moisture to evaporate. For those looking for a columnar cactus, it is a fantastic choice.

How is the Fairy Castle cactus grown?

The fairy castle cactus is a slow-growing, low-maintenance plant that is suitable for novice gardeners. To care for a fairy castle cactus indoors or outdoors, follow these guidelines:

  • 1. Ensure that the fairy castle cactus gets lots of light. House plants preserved as fairy castle cacti should be cultivated in a location with lots of sunlight. The colors will fade and the columns will become crooked if these plants don’t get enough light. Although it prefers full light, this plant can also tolerate some shade.
  • 2. Give the fairy castle cactus only a little water. Avoid overwatering your fairy castle cactus by letting the dirt in its pot get completely dry in between waterings. Your cactus will probably perish as a result of root rot or the attraction of mealybugs caused by standing water or moist soil.
  • 3. Control the environment’s temperature for the plant. The fairy castle cactus thrives in hot conditions as long as it receives enough water. It should, however, be moved indoors if the outside temperature falls below 32 degrees Fahrenheit because it is extremely susceptible to frost. Consider your cactus’ indoor location carefully as well because air conditioning or chilly drafts might be harmful.
  • 4. Sow the fairy castle cactus in soil that drains well. The fairy castle cactus needs soil that drains well, just like many other cacti species. Using soil that has significant amounts of gravel, bark, sand, or perlite will aid in preventing soil saturation.
  • 5. Use a pot with drainage holes that is not glazed. Extra moisture can be absorbed by a terra cotta pot.
  • To promote growth, add fertilizers and plant food. Plant food can be given to the soil or water to promote development during the warmer months, but it shouldn’t be used in the winter when the cactus is dormant. Cactus fertilizer should be applied in the spring as growth begins again.

How frequently should I water my cactus “fairy castle”?

While including 2-3 drainage holes at the bottom of the pot, make sure that any extra water reaches the soil’s surface.

Avoid overwatering the plant as this might reduce yield and invite fungus diseases.


The Fairy Castle Cactus can withstand temperatures of 30 to 90 F. (-1.1-32C). However, the optimal temperature range is 64-79F. (18-26C)

They grow best in summer or warm climates since they flourish best in direct sunshine.

You should water it a bit less and keep it indoors throughout the winter. As too much exposure to the cold can cause the plant to die.

However, some cacti have demonstrated the ability to endure temperatures between 30 F and 90 F. (-1.1 C32C).


Rarely do flowers appear, and even then, only if your species has the ability to produce blossoms.

If so, the flowers may have a tube that is 5.5-8 (14–20 m) in diameter (8-15 cm).

The color spectrum of flowers includes yellow, reddish-orange, creamy white, and greenish-white.

Some flowers can bloom throughout the day, however most flowers bloom at odd hours between midnight and dawn.


We will pick a spot that receives full light or at least a lot of brilliant light for our Fairy Castle cactus. I suggest avoiding full sun for this sort of cactus because certain cacti can still dry out in the presence of the sun’s blistering rays.

The Fairy Castle cactus always tilts toward where the light is coming from. So that the cactus grows straight up, periodically rotate the pot.


Depending on the temperature, humidity, and substrate, water the cactus every two to three weeks in the spring and summer. Watering is not advised in the winter if the temperature falls below 12 to 15 degrees Celsius. The cactus then begins to rest during the winter.

However, it is advised to reduce the frequency of watering at a rate of every four to five weeks following notable changes in light in the case that temperatures do not fall below 15 degrees.


For this Acanthocereus cultivar, fertilizing is not required. However, if the time is perfect, you can give it a very small amount of potassium and mineral-rich liquid fertilizer (like tomato fertilizer, for example), diluted in irrigation water, every two or three waterings.


Repotting, which may be required if the plant has grown, can be done in the spring. Use a mixture of well-drained soil that is two thirds soil and one third draining material, such as perlite or small pebbles, to accomplish this.
