The San Pedro is a cactus with pillars with 4 to 9 ribbons. It grows quite fast, has a strong root system and branches of from the base of the stem. The San Pedro just keeps growing until it succumbs under its own weight. The fallen cactus will in nature root again and produce many new branches.
Growing: This cactus is best cultivated in a sterilized mix of sand, perlite and gravel. Be sure to add small drainage holes in the growing container to help reduce chances of over-watering. The environment should be humid and ideally around 23 °C (73 ºF), but do not place the growing medium directly on a heater. Don’t let the young cacti get in contact with direct sunlight; fluorescent lighting is preferred for the first 3 months. Only after the cacti are a year old should they be placed in direct light.
