Plant Care

Light

Cactus need bright light for optimal growth and plant health. San Pedro prefer full, direct sun. Place in a sunny, south facing window for best results and to avoid any etiolation (long, pale and unhealthy growth due to the lack of light). If you would like to grow your plant outdoors in the summer, be sure to harden them off slowly before exposure to full sun.

Soil

When it's time to repot, use a sharp, well-draining, cactus specific potting soil. We recommend Sol Soils Cactus Gritty Mix. This mix has a unique combination of coconut husk chips, recycled forest products, pumice, calcined clay, granite, and expanded clay for optimal drainage.

Water

Allow soil to completly dry down before giving it a good soak. Hydration events may only occur once per month! Cut back on water during the winter months as light levels decrease.

Fertilizer

Fertilize with a cactus specific fertilizer. We recommend Schultz Liquid Cactus Plant Food. As grow slows in the winter months, fertilization may not be needed.
