Lighting and humidity: Calathea plants thrive in humidity, prefer indirect lighting and will grow best in a shady room. Place your plants away from any open windows with sunlight. You can provide ample humidity by placing a humidifier in the room, or by placing the potted plants on top of a saucer filled with pebbles. Add water to the pebbles and the humidity will travel up through the pebbles and the pot to the plant’s roots.

Watering and fertilizer: Calathea plants don’t like to be heavily watered. Feed them room temperature water when the soil an inch (2.5 centimeters) below the surface is dry. The plants require regular watering during the summer months and less frequent watering during the colder months. You can periodically give the plants houseplant fertilizer.

Maintenance: Groom your calathea plant regularly to keep it looking beautiful. Wipe any dust off the leaves with a clean, damp cloth. Mist the leaves to ensure that all sides of the plants receive humidity and moisture. Remove any yellow leaves to keep your plant strong and growing.
