Soil & Fertilizer

The Peruvian Torch Cactus prefers well-draining, sandy soil with a slightly acidic pH of 5.5 to 7.5. Cacti or succulent mix will be ideal, which is no surprise, because it is a cactus!

During the growing season, from spring to autumn, you can fertilize once a month with a cacti fertilizer. Although, try not to overfertilize the plant. Use low concentrations at one time and see how the plant reacts. If the base turns yellow, this can be due to too much fertilizer.


This cactus should be watered deeply, about once a week, and allowed to fully dry out before being watered again. Over-watering can lead to root rot, so be careful not to water too frequently.


The perfect temperature range for Peruvian Torch Cactus is 68 to 95 degrees Fahrenheit (20 to 35 degrees Celsius). You can grow this South American cactus outdoors in USDA Hardiness Zones in 9-11.

Winter Care

In colder climates, protect your outdoor Peruvian Torch Cactus from frost and freezing temperatures. Bring it inside or cover it with a frost blanket during harsh winter weather. Frost blanket won’t help during long periods of low temperatures.
