Caring for Your Variegated Corn Cob Cactus

A well-draining soil mix is crucial for this plant’s health. Use a cactus or succulent mix or create your own by combining equal parts of potting soil, perlite, and coarse sand. Ensure the container has drainage holes to prevent waterlogging.
Temperature and Humidity
The Variegated Corn Cob Cactus is well-adapted to a wide range of temperatures. However, it’s best to keep it in temperatures between 50-80°F (10-27°C). It can tolerate brief periods of cold, butprolonged exposure to freezing temperatures can be detrimental. This plant prefers low humidity and can struggle in overly damp environments.
Feed your Euphorbia mammillaris variegata with a diluted cactus or succulent fertilizer during the growing season, every 4-6 weeks. Avoid fertilizing in the dormant season to prevent unnecessary stress on the plant.
