The 10 Most Common Myths about Growing Trichocereus

Growing Trichocereus, a genus of cacti highly popular among enthusiasts and collectors, is surrounded by a series of myths that can confuse even the most experienced grower. In this article, we will debunk the 10 most common myths and share practical tips for successful cultivation of Trichocereus. With this knowledge, you can maximize the health and beauty of your cacti, ensuring their optimal and problem-free growth.

Myth 1: Trichocereus can only grow in desert climates

A common mistake is to think that Trichocereus only thrive in desert climates. While they originate from dry regions of South America, these cacti are actually quite versatile and can prosper in a variety of climatic conditions, as long as proper care is provided in terms of light, temperature, and humidity.

Myth 2: They need little water due to their cactus nature

It is true that Trichocereus, like other cacti, are adapted to store water. However, for healthy growth, they require an appropriate watering regimen. During the active growing season, it is essential to provide them with enough water, allowing the substrate to dry between waterings but avoiding prolonged desiccation.

Myth 3: All Trichocereus grow slowly

Another myth is that these cacti have slow growth. In reality, many species and varieties of Trichocereus are fast-growing, especially Trichocereus pachanoi, known as San Pedro, which can grow several centimeters per year under ideal conditions.

Myth 4: It is not possible to grow them indoors

Many people believe that Trichocereus cannot be grown indoors due to their need for direct sunlight. However, with adequate artificial lighting, these plants can happily grow indoors, provided ventilation and watering are properly adjusted.

Myth 5: Their care is the same as any other cactus

Although they are cacti, Trichocereus require specific care that may differ from other members of the cactaceae family. It is important to understand their particular needs in terms of substrate, light, and nutrients to ensure their long-term health.

Myth 6: They do not need fertilization

Like any other plant, Trichocereus benefit from a well-planned fertilization regimen. A balanced cactus fertilizer, low in nitrogen and high in potassium, promotes vigorous growth and resistance to pests and diseases.

Myth 7: They can survive in any type of soil

It is a common mistake to think that Trichocereus can grow in any type of soil. In reality, they require a very well-draining substrate to prevent root rot. A soil mix with mineral elements such as pumice or coarse sand is ideal.

Myth 8: All Trichocereus species are the same

The genus Trichocereus encompasses a variety of species, each with its own characteristics in terms of appearance and cultivation requirements. It is crucial to correctly identify the specific species to tailor care according to its particular needs.

Myth 9: They withstand any type of cold climate

Although some Trichocereus can tolerate slightly below freezing temperatures if completely dry, they generally do not withstand prolonged frosts or wet soils in winter. It is recommended to protect them properly during extreme cold weather.

Myth 10: They are not prone to pests or diseases

Finally, a dangerous myth is to think that Trichocereus are immune to pests and diseases due to their robust structure. They can be affected by scale insects, red spider mites, and fungi if cultivation conditions are not properly managed. Regular inspections and good preventive management are essential to keep them healthy.
