🌱 How to Care for Turk's Cap Cactus to Prevent Mealybugs?

💧 How to Water

Water only when the soil is completely dry, typically every 14 days in summer and every 21-30 days in winter. Never allow water to pool in the saucer or substrate. Overwatering is the primary cause of death for this species.

☀️ Lighting

Requires full direct sunlight for at least 6-8 hours per day. Avoid shade — insufficient light causes distorted growth and may prevent cephalium formation. This is one of the most light-demanding cactus species.

🪴 Ideal Soil

Use a very sandy, well-draining cactus mix. Combine 50% coarse sand or perlite with 50% cactus soil. Ideal pH is 6.0-7.5. Unglazed terracotta pots are ideal as they allow moisture to evaporate through the walls.
