Care Tips
Light
Crown of Thorns thrives in bright, direct sun—ideally 4–6 hours daily. Place near a sunny south-facing window or outdoors in summer.
Watering
Water when soil is fully dry, typically every 2–3 weeks. Overwatering is a common issue; the plant stores moisture in its thick stems, so it tolerates drought well.
Soil
Use a sandy, well-draining cactus mix to avoid root rot.
Humidity & Temperature
It prefers dry conditions and thrives in normal indoor humidity. Keep it in 65–90°F. Protect from frost.
Fertilizer
Feed with a balanced fertilizer every 6 weeks during active growth. Avoid fertilizing in winter.
Propagation
Easily propagated by stem cuttings, though caution is needed—the white sap can irritate skin, so wear gloves.
Troubleshooting
Yellowing leaves: Overwatering.
No blooms: Not enough sunlight or nutrients.
Shriveled stems: Severe underwatering.
Styling Ideas
Crown of Thorns makes a striking standalone plant thanks to its sculptural form and blooms. It pairs beautifully with terracotta pots that highlight its vibrant bracts.
