Light
Grow Calathea in medium to low light. Shield from direct light to prevent sunburn. Moderate, dappled light is also fine.
Water
Keep soil moist at all times – especially during the growing season - but ensure that it is not ‘wet’ or sitting in water (empty out the drip tray). During the winter months the plant will accept a little less water.
Humidity
Maintaining a high level of humidity is important in keeping your Calathea healthy and attractive. Increase humidity by regularly misting the leaves.
Temperature
Temperatures of 15 – 21°C will result in plants that are healthy and vigorous. Reasonable ventilation is fine but keep the Calathea out of strong draughts.
Soil: Well drained, but rich potting mix. Remember to stay away from wet soil or dry, sandy soil.
Fertilizer
Feed monthly during the growing season with a half strength houseplant fertilizer. Don’t feed in winter.
Repotting
If the plant is growing well, aim to repot it every year or every second year during the spring or summer months. Repot it into fresh potting soil.
