Propagating this Echinopsis plant can be done through various methods, such as grafting or taking San Pedro cactus cuttings from the crest. Additionally, it is a friendly plant for both pets and humans. It contains mescaline, an alkaloid that has tremendous healing potential and produces psychedelic effects. 

Watering Needs

The watering needs of the San Pedro crested cactus are similar to those of other cacti. It is important to remember that cacti are adapted to survive in arid environments with limited water availability. 

To keep your crested San Pedro cactus healthy, it is best to water it sparingly. Allow the soil to completely dry between waterings to avoid overwatering, which can cause root rot.  During the growing season, typically spring and summer, you can water the cactus once every two to three weeks. In the dormant season, which is usually fall and winter, reduce watering frequency to once a month or even less. 

When watering, make sure to thoroughly saturate the soil, allowing the excess water to drain out completely. Avoid leaving the cactus sitting in standing water, as this can also lead to root rot in your Echinopsis pachanoi cristata. 

Light Requirements

The crested San Pedro cactus thrives in bright sunlight. It prefers to be placed in a location where it can receive at least six hours of direct sunlight each day. This cactus variety is adapted to high-altitude regions in Peru and Ecuador, where it is exposed to intense sunlight. 

When growing the San Pedro crested cactus indoors, it's important to place it near a sunny window or provide it with artificial grow lights that mimic natural sunlight. If you notice that your San Pedro cactus is stretching or leaning towards one side, it may be an indication that it is not receiving enough light and needs to be moved to a brighter location. 

However, it's important to avoid exposing this crested echinopsis to extreme temperatures, especially during the hottest part of the day. If you live in a region with scorching summers, it's a good idea to provide some shade or protect the cactus from intense afternoon sun. 

Optimal Soil & Fertilizer Needs

The San Pedro crested cactus requires well-drained soil to prevent root rot. To promote drainage, a suitable soil mix for this Echinopsis pachanoi can be a blend of cactus potting mix and perlite or pumice. Avoid using normal potting soil since it holds too much moisture.

When it comes to fertilizing the San Pedro crested cactus, it's best to do so sparingly. During the growing season, you can fertilize the cactus once a month with a balanced, water-soluble cactus fertilizer. Overfertilizing can lead to excessive growth and may harm the San Pedro cactus. Remember, it's important to allow the cactus to rest during the dormant season, typically in fall and winter, and refrain from fertilizing during this time.

When it comes to humidity, the crested San Pedro cactus prefers low to moderate humidity levels.

However, be cautious not to create excessively humid conditions, as it can lead to fungal issues.
