Calathea's prefer a warm location, away from cold drafts. However, the leaves of this plant move up and down following the light, so be sure to feel the soil to ensure you're not mistaking your Calathea's natural movement for needing a drink before giving your plant water. These porous clay stones are a natural, efficient and invaluable material to set your plant up for success. CARE Water: Calatheas prefer the soil to be moist. Only 3 left in stock - order soon.
