To care for your Calathea Setosa (Ctenanthe Setosa 'Grey Star'), provide bright, indirect light, maintain consistently moist but not waterlogged soil, and ensure high humidity with frequent misting or a humidifier. Keep the plant in a warm location, between 65-85°F, away from cold drafts. Water with distilled, filtered, or room-temperature water, and fertilize monthly during the spring and summer with a diluted, balanced houseplant fertilizer.
