Light: Firestick cactus thrives in bright, indirect sunlight. It can tolerate some direct sunlight, especially morning sun, but avoid prolonged exposure to intense afternoon sun, which can scorch the plant.
 
Temperature: This cactus prefers warm temperatures between 65-85°F (18-29°C). It is not frost-tolerant and should be protected from temperatures below 50°F (10°C).
 
Watering: Water the firestick cactus sparingly but deeply. Allow the soil to dry out completely between waterings to prevent root rot. During the growing season (spring and summer), water more frequently, but reduce watering in winter when the plant is dormant.
 
Soil: Use a well-draining cactus or succulent potting mix. A mixture of sand, perlite, and peat moss works well to provide the necessary drainage.
 
Fertilizing: Firestick cacti are not heavy feeders. Fertilize sparingly with a diluted, balanced fertilizer formulated for cacti and succulents during the growing season. Avoid fertilizing in winter.
 
Pruning: Minimal pruning is required for firestick cacti. Trim back any dead or damaged stems with clean, sharp pruning shears. Wear gloves when handling the plant to avoid contact with the milky sap, which can cause skin irritation.
 
Potting: Repot firestick cactus every 2-3 years or when it outgrows its current pot. Choose a pot with drainage holes to prevent waterlogging.
 
Safety: Handle firestick cacti with care and wear protective gloves when pruning or handling to avoid contact with the sap, which can irritate skin and eyes.
