🌱 How to Care for Great Stonecrop to Prevent Aphids?

💧 How to Water

Let the soil dry out completely between waterings; this succulent stores water in its fleshy leaves and stems and is highly susceptible to rot if kept too wet.

☀️ Lighting

Provide full sun for at least 6 hours a day for the sturdiest growth and best flowering; in hot climates it tolerates light afternoon shade, but too much shade causes weak, floppy stems.

🪴 Ideal Soil

Use a well-draining soil rich in mineral content, ideally with added grit or sand; calcareous, stony soils that mimic its native rocky slopes work best.
