Euphorbia (Succulent Types): Crown-of-Thorns & Relatives for Sunny Windows

Indoor Culture (Winter)

• Light: 6–8 hours direct sun.
• Water: Keep nearly dry.
• Fertilizer: None.

Spring–Fall Care

• Water when top inch of mix is dry.

• Protect from scorching midday sun—move to partial shade outdoors.

Safety First

All euphorbias exude a milky, latex sap that irritates skin and eyes. Wear leather gloves; use tongs when repotting spiny varieties.
