Water
Water thoroughly when the soil is completely dry. Reduce watering significantly in cooler months to prevent root rot.
Ensure excellent drainage to avoid waterlogging, as these cacti prefer arid conditions and are susceptible to overwatering.
Also known as Sacred Column Cactus · San Pedro Cactus · Trichocereus Pachanoi

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the soil is completely dry. Reduce watering significantly in cooler months to prevent root rot.
Ensure excellent drainage to avoid waterlogging, as these cacti prefer arid conditions and are susceptible to overwatering.
Pruning is generally not required unless removing damaged or diseased parts. If propagation is desired, stems can be cut cleanly with a sterilized knife.
Allow cut surfaces to callus over for several days before planting.
Easily propagated from offsets or stem cuttings. Allow cuttings to dry and form a callus for several days to a week before planting in well-draining cactus mix. Offsets can be gently removed and treated similarly.
Repot every 2-3 years, or when the plant outgrows its container. Use a gritty, fast-draining cactus mix. Repot in spring before active growth begins. Handle with care to avoid spine damage.
Choose a pot only slightly larger than the previous one.
