Calathea Sanderiana Care Guide


Also known as the pin-stripe Calathea or Calathea sanderiana. This Calathea is native to the tropical rainforests of Bolivia.


The calathea sanderiana prefers a medium light. Keep her away from any windows as the bright sun will burn her leaves. While Ziggy likes medium light she will be tolerant of lower light in the winter months when sunlight is minimal.


The calathea sanderiana small amounts of water on a regular basis so it’s best to check her soil weekly to make sure it doesn’t dry out too much. Getting the balance may be tricky as she won’t like his soil to completely dry out or be too soggy. In the winter time you can reduce her watering schedule to once a week but always check her soil is dry before you water her.


The calathea sanderiana is from a very humid climate and will appreciate moisture on her leaves. To replicate her natural habitat you can place her next to a humidifier, group her with other humidity loving plants or place her in a bathroom.


The perfect indoor temperature for the calathea sanderiana is between 18-24 degrees celsius. As long as the indoor temperature doesn't dip lower than 18°C Ziggy will be happy.


To promote growth use fortifying fertiliser every 4-6 weeks in the months from March-September. Make sure to dilute the fertiliser to a quarter strength to avoid fertiliser burn to Ziggy’s roots.


The calathea sanderiana is fast growing and will produce a lot of new growth over the spring and summer months. Repot her every year to give her more room to grow. You can check the bottom of the nursery pot. If you can see her roots sticking out the bottom, it's time to repot.



Curling leaves - The curling leaves are a sign that the Calathea is suffering from the cold. Have a look around the home to make sure Ziggy is not close to any windows, radiators or doors that could be causing drafts.

 Drooping leaves - The calathea sanderiana prefers her soil to be semi moist without drying out completely between each water. When the soil dries out Ziggy’s foliage will start to droop and this will indicate that she needs a drink. If the first few inches of soil is bone dry to touch, it’s time to water. It’s worth noting that Calathea’s leaves move with the light. The leaves appear droopy during the day and will move upwards in the evening. 

Yellow leaves - Yellow leaves often indicate that the calathea sanderiana has been overwatered. You can remove this leaf by cutting the stem at the base of the plant. Reduce her watering schedule especially in the winter months.

 Brown edges: The brown edges could be caused by a variety of things. 

    1. The calathea sanderiana is very sensitive to hard water which could be causing the leaves to brown. Use filtered or rainwater moving forward.
    2. Lack of humidity levels. Be sure that the calathea sanderiana is near a humidifier or a pebble tray is used underneath his pot.
    3. Occasionally the brown tips could be from over fertilising, it is good to note that Ziggy’s roots are very sensitive. Always dilute a generic houseplant fertiliser. 



Top tip 1: The calathea sanderiana is very draft sensitive. She will suffer from cold damage if she is placed in a draughty spot. Keep her away from any open windows or draughty hallways. 

Top tip 2: Clean her foliage with the beautifying leaf shine once every three weeks to remove any dust. 

Top tip 3: Always water and mist Ziggy with filtered or rain water. Harsh chemicals found in tap water will cause her edges to brown.
