🌿 Care Tips

• Light: Bright, indirect light to several hours of direct sunlight. A sunny window is ideal. Acclimate gradually to strong sunlight to prevent scorching
• Water: Allow soil to dry out completely between waterings. Water thoroughly, then let excess water drain. Reduce watering significantly during winter
• Humidity: Prefers low humidity and good airflow. Average household humidity is generally fine
• Temperature: Prefers 65 to 85°F. Protect from frost and prolonged temperatures below 50°F
• Pet Friendly: Yes, generally considered non-toxic to cats and dogs, but its sharp spines can cause injury

✨ Fun Fact

Fairy Castle Cactus gets its name from the way its many upright stems resemble the towers of a tiny medieval castle. It grows slowly, and flowering is uncommon indoors, so this little fortress is usually grown for its unusual shape rather than its blooms. No royal gardener required!
