Calathea Triostar Care Guide

Last Updated: June 2, 2022

Basic Calathea Triostar Care

Part of the Prayer Plant family, Calathea Triostar are known for their incredible colourful leaves with pink undersides. Below you will find our detailed Calathea Triostar Care Guide with all the information you need to help your plant thrive.


Bright Indirect Light

I love the sunshine but too much direct light will damage my leaves.


Water Moderately

I don’t like my soil to be too dry or too soggy. Little and often is what I’m after.


High Humidity

I thrive in humid environments so please mist my leaves every so often.


Potting Soil

I need soil specifically for indoor plants as it retains the right amount of water.

They love bright, indirect light

Calathea Triostar love sunshine but can get damaged easily if they are exposed to any direct light. We recommend finding a spot with plenty of indirect light. You may want to adjust where you place your plant depending on the seasons and the sun strength. Using a light monitor is a great way to determine if your plant’s getting enough light.

Keep the soil slightly damp

Remember there is a big different between moist and waterlogged soil. If your Calathea Triostar sits in water for too long, the roots will begin to rot and the plant will quickly become limp and mushy. Always check the top few inches of the soil before watering. Using a moisture meter helps to figure out how much moisture is in the soil so you don’t under or overwater.

Calathea Triostars need a humid environment

One of the most important things about caring for a Calathea Triostar is keeping the humidity levels up. A great way to do this is misting the plant using a spray bottle every few days (or more if you can) or using a humidifier to keep a consistent level. You can find out more about raising the humidity for your plant in our guide.

Calathea Triostar hate cold temperatures

We recommend finding a nice warm spot for your Calathea Triostar as they prefer slightly warmer temperatures. Be careful not to place your plant near AC vents or any drafty windows or doors as the cold air can cause long-term shock. We always check the spot our plants are in using a digital thermometer. They will help avoid drafts or hotspots.

Fertilise your Calathea Triostar in the growth period

We recommend feeding your Calathea Triostar once a month in spring and summer when it is producing new leaves. Our plants love the liquid fertiliser from Miracle Gro. Always dilute the fertiliser to half the recommended strength.

Calathea Triostar plants are non-toxic

One great thing about the Calathea Triostar is that they are non-toxic for both pets and humans, so you don’t need to worry about moving them out of reach.

Propagate your Calathea Triostar through division

Spring is the best time to propagate your Calathea Triostar as the growth period gives it the best chance of success. You should propagate by diving the mother plant and placing in fresh soil. Make sure that each new plant has a good chunk of the root system.
