🌱 How to Care for Blue-green Adenia to Prevent Sunburn (Sun Scorch)?

💧 How to Water

Water thoroughly once the soil has dried out completely, allowing excess water to drain away. Drastically reduce watering when the plant drops its leaves in autumn, and keep it almost entirely dry through the winter dormancy period to avoid rot in the valuable caudex.

☀️ Lighting

Provide the plant with very bright light or several hours of direct sun on the climbing stems and leaves to keep growth compact, but shield the swollen caudex itself with light shade – unprotected full sun can cause permanent sunscald marks on the base.

🪴 Ideal Soil

Use a highly mineral, fast-draining mix (e.g., cactus soil with plenty of added pumice, grit, or coarse sand) with a pH of 6-7. Poor drainage is the most common cause of caudex rot.
