Calathea | 'Grey Star'

Asch Building


Origin: South America

Height: Up to 2 ft (60 cm)

Light: Moderate to bright, indirect sunlight. Hot, direct sun will cause leaves to turn brown.

Water: Aim to keep the potting mix lightly moist; never allow it to dry out. It's a good idea to pot Calathea orbifolia in a container with drainage holes. Water thoroughly, then empty the drainage tray to prevent root rot. Avoid overwatering, which will cause crown rot.

Humidity: Calatheas love high humidity, and this tropical houseplant is no exception. Try to maintain 60% relative humidity year-round. It's a good idea to use a cool-mist room humidifier near your plant.

Temperature: Average to warm room temperatures (65-80°F/18-27°C) year-round. It will tolerate a low of 60°F/16°C.

Soil: Peat-rich potting mix; African violet potting mix is ideal.

Fertilizer: Feed monthly spring through fall with a balanced (such as 10-10-10 NPK) water-soluble fertilizer.

Propagation: Division; divide large plants in spring.
