Simple Guide to Using Trichocereus in Cactus Production

The genus Trichocereus (also currently classified in modern taxonomy as part of the genus Echinopsis) consists of columnar cacti native to South America, especially Bolivia, northern Chile, Ecuador, and Peru. The most well-known and widely used species, Trichocereus pachanoi or San Pedro, stands out for its fast growth, ornamental value, ethnobotanical importance, and ease of cultivation.

Selection and Propagation of Trichocereus

Most Recommended Species for Trichocereus Cultivation

• T. pachanoi (San Pedro): Very popular, ideal for beginners.
• T. peruvianus and T. bridgesii: Similar growth speed and attractive morphology.

Propagation Methods for Trichocereus

• By cuttings: The fastest method. Cut stem segments between 15-30 cm, allow to callus in shade for one week, and plant in prepared substrate.
• By seed: Slower, but produces many plants. Sow in spring on moist, fine substrate, cover lightly, and maintain moisture until germination (2-4 weeks).

Preparation of Substrate and Pot for Trichocereus

• Essential drainage: Use special commercial cactus mixes or make your own mix with 1/3 topsoil, 1/3 coarse sand, and 1/3 volcanic gravel.
• Ideal pH: Between 6.0 and 7.0.
• Drainage layer: Place gravel or volcanic rock at the bottom of your pots or beds.

Light, Temperature, and Watering Conditions for Trichocereus

• Light: Full sun, although during the hottest hours it is advisable to provide slight shade.
• Temperature: Prefers between 15 and 30°C. Tolerates light frost, but if the climate is very cold, protect it.
• Watering: Abundant only during the growth period (spring-summer). Always wait until the substrate is dry, especially in winter.

Fertilization and Seasonal Care for Trichocereus

• Special cactus fertilizer: Apply only during spring and summer, every 30 days. Reduce or suspend fertilizers in autumn and winter.
• Cleaning: Remove dry or damaged stems and check for pests such as scale insects or mites.
• Substrate renewal: Transplant every 2-3 years to stimulate growth and avoid depleted soils.

Recommendations for Commercial Production of Trichocereus

• Choose clones or seeds of good origin, preferably varieties already adapted to the local climate.
• Keep growth and production records to optimize selection and care.
• Consider cutting production as a quick method to multiply healthy and vigorous plants.
• Ensure adequate spacing to allow the development of robust and healthy stems.

Ethical-Legal and Safety Considerations in Trichocereus Cultivation

Remember that although the cultivation of Trichocereus is usually legal for ornamental purposes, this genus also contains psychoactive alkaloids such as mescaline. Inform yourself about local regulations if you plan medicinal, traditional use, or export.

Key Tips for the Successful Trichocereus Producer

• Perform visual monitoring weekly to detect pest or disease problems in time.
• Favor propagation by cuttings in spring and summer to maximize production.
• Patience is essential: the true appeal of Trichocereus, such as its large nocturnal flowers or sculptural form, appears after several years of careful cultivation.

Summary for Successful Trichocereus Production

Proper species selection, suitable substrate, optimal drainage, balanced care in light and watering, and respect for legality will open doors to a successful, sustainable, and professional production of Trichocereus.
