Ferocactus peninsulae, commonly known as the Baja Barrel Cactus, is a striking succulent native to the Baja California Peninsula in Mexico. Here's a care sheet based on factual information:


  • Light Requirements: Ferocactus peninsulae prefers full sun to thrive. It should receive at least 6 hours of direct sunlight daily. In hotter regions, some protection from intense afternoon sun may be necessary to prevent sunburn.


  • Watering Needs: Water sparingly but deeply during the growing season (spring and summer). Allow the soil to dry out completely between waterings to prevent rot. Reduce watering significantly in winter when the plant is dormant.


  • Soil Type: Plant Ferocactus peninsulae in a well-draining cactus mix. A sandy or gritty soil with excellent drainage is essential to prevent waterlogging, which can lead to root rot.


  • Temperature Range: Ferocactus peninsulae prefers warm temperatures between 70-90°F (21-32°C) during the active growing season. It can tolerate slightly cooler temperatures but should be protected from frost, as it is not frost-tolerant.


  • Humidity Preference: Ferocactus peninsulae prefers low humidity levels typical of desert environments. It can tolerate dry air and does not require high humidity.


  • Fertilization: Feed Ferocactus peninsulae sparingly with a balanced, diluted fertilizer formulated for cacti once in early spring as growth begins. Avoid fertilizing during fall and winter when growth slows down.


  • Propagation Methods: Ferocactus peninsulae can be propagated from seeds or by removing offsets (pups) that develop around the base of mature plants. Allow offsets to dry and callus for a few days before planting them in well-draining soil.


  • Pruning Requirements: Minimal pruning is needed. Remove any dead or damaged parts of the cactus with clean, sharp scissors or pruning shears.

Pests and Problems:

  • Pest Control: Monitor for common cactus pests such as scale insects or mealybugs. Treat infestations promptly with insecticidal soap or neem oil. Ensure good air circulation around the plant to prevent fungal issues.

Potting and Repotting:

  • Repotting Needs: Repot Ferocactus peninsulae every 2-3 years or when it outgrows its current container. Choose a slightly larger pot with drainage holes to accommodate its root system.

Special Care Notes:

  • Dormancy: Ferocactus peninsulae may go somewhat dormant in winter, requiring less water. However, it does not undergo a complete dormancy like some cacti.
  • Sun Exposure: Provide full sun exposure for optimal growth and flowering. Insufficient light can cause elongation of the cactus and affect its overall health.

By following these care guidelines, you can help your Ferocactus peninsulae thrive and showcase its impressive barrel-shaped form and occasional blooms in your cactus garden or collection. This species' adaptability to arid conditions makes it a resilient and rewarding plant for cactus enthusiasts.
