Introducing the totem pole cactus, known as Pachycereus schottii monstrosus, which is a strikingly beautiful plant. Native to North America, this slow-growing cactus is also known as Lophocereus schottii var. monstrous, or monstrous whisker cactus. It got its common name from its textured stems, which look like totem poles with many faces.

The totem pole cactus grows slowly and is distinguished by its tall, columnar growth habit and bumpy, spineless skin. Indoors, it can grow to 8 feet tall and 4 feet wide. When grown outdoors, this columnar cactus can grow up to 20 feet tall.

Over time, this cactus develops several upright arms. When a stem falls over in the wild, it roots along its side.

This cactus can be used as a focal point in cactus gardens, as well as in attractive containers or raised beds alongside other cactus and succulent plants.

It can also be accented around pools or ponds or used as a xeriscape plant in combination with other desert plants. To create a vertical or architectural effect, place it against a tall wall.

The totem pole cactus blooms at night, produces light pink blossoms in late spring that open at dusk and close by mid-morning. These flowers attract pollinators such as bees and butterflies, contributing to the plant's reproductive success. It also produces an edible egg-shaped red fruit with red pulp.

The spines on these towering totem pole cacti are shorter than other Arizona giants, such as the saguaro or organ pipe, allowing its bright yellowish green stem to be prominently visible. 

Totem cactus propagation can be done through stem cuttings or divisions. To propagate by stem cuttings, you can cut a piece of the cactus stem (ensure it's a healthy, mature stem) and let the cut end callus over for a few days. Then, plant the cutting in a well-draining soil mix and keep it slightly moist until roots develop. Another method is by division, where you carefully separate offsets or pups from the main plant and replant them.

Watering Needs 

The Totem Pole cacti prefer infrequent watering to mimic their natural habitat.  They prefer to be watered using the "soak and dry" technique. This involves thoroughly watering the plant before allowing it to completely dry out between watering sessions. Overwatering can lead to root rot, so it's crucial to avoid keeping the soil constantly moist. Adjust your watering frequency based on the seasons. 

In the spring and summer, during the growing season, you can water your Totem Pole cactus every 3-4 weeks. In the fall and winter, during the dormant season, reduce watering to once a month or even less, as the cactus's growth slows down.

Keep an eye on your cactus to gauge its watering needs. If the cactus starts to show signs of wrinkling or softness, it may be a sign of underwatering. On the other hand, yellowing or mushy stems could indicate overwatering. Adjust your watering schedule accordingly based on how your Totem Pole cactus responds.

Light Requirements 

When growing indoors, the totem pole cacti thrive in bright, indirect light. Place your cactus near a sunny window where it can receive plenty of natural light. However, be cautious of direct sunlight, especially during the intense afternoon hours, as it can scorch the cactus. If your indoor space lacks natural light, you can supplement with a grow light to ensure your Totem Pole cactus gets the light it needs to stay healthy and vibrant.

When growing your totem pole cactus outdoors, it's crucial to provide it with ample sunlight. These cacti enjoy full sun exposure, so choose a spot in your garden or patio that receives at least 6-8 hours of sunlight per day. Ensure that the outdoor location has well-draining soil to prevent waterlogging, which can harm columnar stems of your cactus. During hot summer months, providing some protection from the intense midday sun can help prevent sunburn on the cactus's stems.

Optimal Soil & Fertilizer Needs 

The totem pole cactus prefers sandy, well-drained soil, as excess moisture can promote root and stem rot. Planet Desert specializes in succulents and has specialized cactus potting soil that includes an organic substrate with mycorrhizae to help with the growth of a healthy root system to help your cactus plants thrive. As an okay alternative, you can create your own potting mix by combining equal portions of perlite, coarse sand, and good natural potting soil.

The totem pole cactus is unable to tolerate wet feet, especially in winter, when they aren't actively growing and absorbing water. This makes them perfect for gravelly soil and rock gardens, especially ones built on slopes. As a rule, hillsides have better drainage than flat areas. 

Natural fertilizers with an equal ratio of 5-10-5 (NPK) are the best choice as they last longer and keep your soil alive by adding other beneficial compounds and microbes that encourage plant health and nutrient absorption. So, skip those harsh chemicals and give your totem pole cacti some love with a good natural fertilizer! 

Hardiness Zones More

When growing indoors, it thrives in typical room temperatures ranging from 60°F to 75°F. It's essential to avoid sudden temperature fluctuations and drafts, as they can stress the cactus. In terms of humidity, these cacti prefer low to moderate humidity levels, making them well-suited for indoor environments with average humidity levels. Providing good air circulation around the plant can help prevent any humidity-related issues.

For outdoor cultivation, your totem pole cactus is well-suited to warm and arid climates. It thrives in USDA hardiness zones 9 to 11, which typically experience mild winters and hot summers. These cacti can tolerate temperatures as low as 20°F but prefer temperatures above 50°F for optimal growth.

Final Thoughts

Overall, the Totem Pole cactus is a fascinating plant known for its unique appearance and low maintenance requirements. With its tall, columnar shape and lack of traditional spines, it adds a modern and sculptural element to any space. To care for your Totem Pole cactus, ensure it is planted in well-draining soil, receives plenty of sunlight, and is watered sparingly, allowing the soil to dry out between waterings. Avoid overwatering and extreme temperature fluctuations to keep this cactus thriving and looking its best.
