🌱 How to Care for Green Dunce Cap to Prevent Aphids?
💧 How to Water
Allow the soil to dry out completely between waterings—water only about every 12-14 days, and avoid getting water into the rosette itself, as this increases the risk of rot.
☀️ Lighting
Place the plant in a spot with plenty of direct sunlight, such as near a south-facing window or outdoors in full sun. Insufficient light results in elongated, stretched rosettes.
🪴 Ideal Soil
Use a sandy, very well-draining soil—preferably a pre-mixed cactus/succulent soil. The plant does well in nutrient-poor soil as long as the drainage is good.
