🌱 How to Care for Sand dollar cactus to Prevent Overwatering?

💧 How to Water

In spring and summer, water thoroughly only when the mix is completely dry, usually every 2 weeks. Stop watering when temperatures drop below about 15 °C and keep dry through winter. Cracks in the body mean too much water; a deflated look means it is thirsty.

☀️ Lighting

Lots of light: 6 hours of direct sun or an equivalent grow light, with light shade at the peak of summer heat to prevent scorch. Indoors, the brightest window in the house.

🪴 Ideal Soil

Free-draining mix, about 90% mineral (coarse sand, pumice or grit) and 10% organic, with pH 6 to 7. Use a deep pot with a hole, as the plant has a taproot.
