How Often To Water Calathea Triostar

Keep it moist, check the soil twice a week and water it if the top 50% has dried out.

Tip: Use filtered tap water as they are super fussy about hard water, you can use a brita filter and let the water stand overnight.


Use a well diluted balanced feed every 3 weeks in the spring and summer.


They want a well draining mix to avoid root rot issues and a rich soil, so get a good rich potting compost and mix it with perlite (80% compost to 20% perlite).

When to Repot Calathea Triostar

Check the roots each year at about easter time and give it a bigger pot they are crowded.


Aim for 70% or more, they really need high humidity or they get curling leaves. At least keep them in a humid room or with other plants and mist them occasionally.

Tip: Keep them humid, at least 60% in the day and they’ll be ok with a bit less at night. You can buy a humidity meter (affiliate link) to keep an eye on maximum and minimum levels.


A good daytime temperature is 15-27°C (59-81°F). and try to keep them above a minimum of 12°C (54°F) at night and in the winter.
