This cactus is found in Northwestern Argentina were it is known as Cardon Grande or Cardon santo 'sacred cactus. Often times it's confused with another species known as T. pasacana, of the same geographical region. The difference between T terscheckii and T pasacana is the branching, fewer number of ribs, different spines, and large flowers. Its an ethnobotanical because of its comparability to Peyote or San Pedro. It's also one of many mentioned in the book, "Peyote, And Other Psychoactive Cacti"
The Trichocereus Terscheckii ( Argentine saguaro, Cordon Grande ) cactus is a heavyweight champion of the Trichocereus species. These cacti can grow to an astonishing 30 + feet. The photo below was taken in Argentina. The arms of this massive beast weigh in at up to 100 + pounds per linear foot. This bad boy can easily be grown from seeds or cuttings, also known as propagation.
When cultivating this cactus we recommend using an organic fertilizer high in potassium and phosphorous, but lower in nitrogen, because nitrogen does not help the development of succulent plants, making them too soft and full of water. Argentine Saguaro can endure long periods of time without watering. As it gets colder close to winter the length of time without watering can be extended. Watering the Trichocereus Terscheckii should only be done when the soil is completely dry, about every 4-5 weeks.
