Detailed Calathea Triostar Care

Whether you're looking to make sure your Calathea Triostar is in it's perfect conditions, or looking to see if one could work for your space. We've got you covered.

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.

If you notice that your Calathea Triostar is starting to develop yellow leaves, it is usually caused by overwatering. Check the moisture in the soil and replace if necessary. In future, we recommend using a moisture meter to ensure you only water your Calathea when needed. You can also use terracotta pots rather than plastic ones which allow some of the water to escape out of the sides.

Pale leaves on a Calathea Triostar are a sign that there is too much moisture in the soil. Adjust your watering schedule and make sure there are drainage holes in the pot (and that they are not blocked by anything).

Dry, cirpsy brown edges on the leaves of your Calathea Triostar is a signal that either it needs to be watered more often, or that the humidity levels are too low. The easiest way to increase the humidity level is by using a humidifier. You can find out more about how to increase the humidity for your houseplants in our guide.

Wrinkly, withered leaves on a Calathea Triostar are a sign that the air in the room is too dry. Try to mist your plant regularly using a spray bottle or move it to the kitchen or bathroom where humidity levels are naturally higher. We also recommend every plant parent use a humidifier to keep a nice constant humidity level in your home.
