🌱 How to Care for Split rock to Prevent Scale Insects?

💧 How to Water

Water only when the substrate has completely dried out and the leaves wrinkle slightly—then water thoroughly until water flows freely from the drainage holes. In summer, during the dormancy period, reduce watering almost to zero, and in winter, provide water rarely but regularly so the plant can bloom.

☀️ Lighting

Place the plant in the brightest spot in the house, preferably on a south or west-facing windowsill. It tolerates a few hours of morning sun, but harsh, midday rays in midsummer can burn the leaves—in such cases, it is worth lightly shading the position.

🪴 Ideal Soil

Plant in a heavily mineral, fast-drying substrate—ideally a ready-made cactus and succulent mix enriched with perlite, pumice, or grit, so that at least half of the volume consists of mineral fractions. Always use a pot with a drainage hole.
