Calathea Medallion Care Guide


Also known as the Prayer Plant or the Calathea Roseopicta Medallion. She is native to the tropical forests of Brazil.


The calathea medallion prefers a medium light. Avoid placing her in a bright spot as this could cause the patterns on her leaves to fade. She is a low light tolerant plant but will prefer a medium light.


Getting the balance may be tricky as she won’t like her soil to completely dry out or be too soggy. Every week check the first 2 inches of the soil and make sure it is dry before watering. In the winter time she will need less water. Make sure she is never sitting in excess water as this could lead to root rot.


The calathea medallion is from a very humid climate and will need high levels of humidity to thrive. She will suffer in dry spaces so it’s important to keep her away from any radiators or underfloor heating. Keep her humidity levels high by using a pebble tray, using a humidifier or placing her in the bathroom.


The perfect indoor temperature for the calathea medallion is between 18 - 27°C as long as the indoor temperature doesn't dip lower than 18°C Catherine will be happy.


Use our fortifying fertiliser once a month between March-September. Do not fertilise in the winter months.


The calathea medallion may need to be re-potted once every year or two years. Look for signs that she has outgrown her nursery pot. Check the bottom of the pot for roots sticking out the bottom.



Drooping leaves -Drooping leaves are usually a sign that the calathea medallion needs a drink. In some cases it has been noticed that Calathea’s move with the light. The leaves appear droopy during the day and will move upwards in the evening.

Yellow leaves - The most common reason for yellow leaves is from overwatering. The best way to know if the calathea medallion needs watering is by feeling the first few inches of her soil. It’s worth noting that humidity loving plants tend to favour humidity over regularly watering. Another cause for Catherine’s leaves turning yellow is from lack of sunlight. Make sure the calathea medallion is in a well lit room.

 Crispy brown edges - The brown leaves could be caused by a variety of things. 

  1. Catherine is sensitive to hard water which could be causing the leaves to brown. If possible use filtered or rainwater. 
  2. Lack of humidity levels. Be sure that Catherine is getting regularly misted, placed near a humidifier or a pebble tray is used underneath her pot.



Top tip 1: The Calathea medallion is a perfect bathroom plant due to her love of high humidity. 

Top tip 2: The Calathea medallion can be quite sensitive to drafts and could suffer from cold damage. Keep Catherine away from any open windows or frequently used doors. 

Top tip 3: Watering her with filtered or rain water. She will react badly to the chemicals found in tap water.
