A Perfect Addition to any Cactus Lover’s Shrine

Step into the realm of nature’s architectural wonders with the Royal Red Cathedral Cactus. A rare and mesmerizing gem, this cactus stands tall, boasting deep ruby red columns that appear as gothic spires of ancient cathedrals. Each segment is intricately designed with subtle ribbing, giving it depth and dimension.

Perfect for both novice gardeners and cactus aficionados, the Royal Red requires minimal care, thriving in well-draining soil and basking in filtered sunlight. Its dramatic color palette serves as a bold statement piece for interiors, adding a touch of desert allure to any space.

Caring for your Cathedral Cactus

The Royal Red Cathedral Cactus is also a testament to resilience, thriving where few plants can. With consistent care and an understanding of its basic needs, you’ll find that the Cathedral Cactus is not only easy to maintain but also immensely rewarding. Whether you’re a seasoned gardener or just starting out, this cactus offers a blend of beauty and simplicity that can grace any space.


Sunlight is essential for all cacti, and the Cathedral Cactus is no exception. They thrive best in full sunlight when outdoors. If indoors, position it near a south or west-facing window where it can receive ample sunlight. If the cactus starts to look elongated or discolored, it may be a sign of insufficient light.


Like most cacti, Cathedral Cacti prefer well-draining soil. Use a cactus mix or create your own with one part potting soil, two parts coarse sand, and one part perlite. This combination ensures that excess water drains quickly, preventing root rot.


Overwatering is a common mistake with cacti. Cathedral Cacti are drought-tolerant and have adapted to survive in arid conditions. In spring and summer, water once the top 1-2 inches of soil feels dry to the touch. In the dormant winter months, cut back significantly, watering only when the soil is completely dry.


Cathedral Cacti are warm-weather plants. They flourish in temperatures between 70°F and 100°F (21°C to 37°C) during the day and prefer a drop of about 10-15 degrees at night. While they can tolerate minor frosts, prolonged exposure to temperatures below 50°F (10°C) can harm them. If you’re growing your cactus outdoors in a cooler climate, consider bringing it inside during the colder months.


While not heavy feeders, Cathedral Cacti benefit from a boost during their growing season. Use a cactus-specific fertilizer diluted to half-strength. Fertilize once at the beginning of spring and again in mid-summer. Avoid over-fertilizing as this can lead to overly rapid growth and a weak plant.


Generally, Cathedral Cacti require minimal pruning. However, if there’s any dead or damaged tissue, it’s a good idea to remove it to prevent potential diseases. When handling your cactus, always use protective gloves or wrap it in layers of newspaper to avoid the spines.


Cathedral Cacti can be propagated from seeds or offsets. Offsets are the small cacti that grow at the base of an established plant.

    She is beautiful, although she has a few blemishes. It was a big contrast to the other travel companions I ordered, which were in perfect condition. So far, the plant looks healthy (fingers crossed).

    I felt that for a “medium” size plant it was quite small. It was about 9 inches in height and came in a 4-inch pot.

    It’s small but soooo cute very happy

  11. Amparo Colon (verified owner)
