How to Grow Calathea Triostar From Seed

What you’ll need:

Propagation should take place in spring or summer as these are peak growing seasons. Propagate can only happen when your plant is large enough to have separate clumps of root and stem.

  • Carefully remove your plant from its pot
  • Loosen the roots and soil with your fingers
  • Using a pair of sharp shears, make a clean cut, ensuring your cutting contains roots and leaves.
  • Plant your new cutting in pots with fresh soil.
  • Replant your original Calathea Triostar in its pot with fresh soil
  • Water all plants until the soil is moist.
  • Keep your new plants in a warm area with indirect sunlight.
  • Make sure all soil remains moist but not soggy.

Calathea Triostar Growing Conditions

Due to being a tropical plant, the Calathea Triostar has specific growing conditions. However, these conditions aren’t too complicated and can be created artificially in the home.

Once you’ve planted your Calathea Triostar, you can begin providing the right care needed for a happy and healthy tropical potted plant. First, let’s take a look at how to plant and care for the Calathea Triostar in the right way:

Calathea Triostar Potting & Soil

Tropical plants require well-draining soil due to the high levels of water they need. Keeping your Calathea Triostar hydrated is imperative, but overwatering is a common mistake many Calathea Triostar owners make. Investing in well-draining soil helps reduce the risk of overwatering.

To further assist your plant drainage, you can purchase a pot with drainage holes in. These holes help any excess water drain from your plant, reducing the risk of root rot.

Calathea Triostar Water Requirements

On average, the Calathea Triostar requires watering every five to ten days. However, this is just an estimate, and you should always check the condition of the soil before watering. The soil your Calathea Triostar is in needs to remain moist. As a plant owner, you need to monitor the soil to ensure it’s never too dry or too wet.

Purchasing a mister can help promote healthy leaves if you live in an area with low humidity. Dry or discolored leaves suggest your plant is dehydrated, and so, a mister can help improve these conditions.

Calathea Triostar Light Requirements

Controlling the light exposure your plants are subject to is generally a bit more tricky. For example, the Calathea Triostar enjoys high heat but indirect bright sunlight. If you consider the kind of exposure the Calathea Triostar would have received in its native tropical environment, this can help us understand the plant requirements.

Try to position your Calathea Triostar on a windowsill that receives partial light exposure throughout the day. Positioning your plant in direct sunlight for too long can cause sunburn. Make sure to move your Calathea Triostar out of the sun if it’s been sitting there too long.

The Calathea Triostar doesn’t require fertilizer to grow, but some owners choose to use fertilizer to promote growth in certain seasons. If you choose to use fertilizer on your Calathea Triostar, make sure to use this during the spring and summer months, as these are the Calathea Triostar’s growing seasons.

Best Calathea Triostar Companion Plantings

Whilst many people know the Calathea Triostar as an indoor plant, the Calathea Triostar lives outside too. Those who live in a tropical climate may have seen beds of Calathea Triostar outside.

If your Calathea Triostar is outside, make sure to surround it with other Calathea plants or similar tropical plants with the same requirements. Due to the natural tropical climate, you won’t have to tend too much to your tropical plants.

An indoor Calathea Triostar should be in its own individual pot. The plants you choose to surround your potted Calathea Triostar with don’t matter. Just make sure to attend to all your potted plants with their individual needs and maintenance.

Calathea Triostar Diseases and Common Problems

Limp Stem

Calathea Triostar Diseases

A limp stem means your Calathea Triostar is cold. This is quite common in naturally colder climates. Move your Calathea to a warmer spot with more sunlight exposure. You can also invest in a humidifier to increase the humidity levels inside your home.

Falling Leaves

Falling leaves mean your plant is dehydrated. To rehydrate your Calathea, you need to remove your Calathea Makoya from its pot and submerge it in water.

Let your Calathea Triostar dry naturally before repeating the same method two to three times. After your Calathea Triostar is dry, repot the plant in fresh soil. Use a mister to improve hydration.


The first step to take when you encounter pests is to make sure your plant isn’t in contact with any other houseplants. Secondly, run a stream of water from your plant to wash away pests. Finally, if this fails, purchase a chemical pest remover.

Discolored Leaves

Discolored leaves indicate your plant isn’t getting the right nutrients. Using fresh, filtered water will improve your plant’s health and coloring.
