How to propagate a Calathea Triostar

Last Updated: October 25, 2022

Known for their incredible colourful leaves, Calathea Triostar plants aren’t always the easiest to take care of. They can be quite fussy when it comes to curling or brown leaves but when you get the care right, it’s really worth it. However, one thing that is super easy when it comes to Calathea Triostars is propagation. We have written this propagation guide to give you all the information you’ll need to propagate your Calathea Triostar. 

Below you’ll find a step by step process, as well as what tools and equipment are needed, what problems you might face and how to fix them as well as all of our top tips to help you propagate your Calathea Triostar successfully.

Why propagate your Calathea Triostar?

Before we get into the individual steps required to propagate your Calathea Triostar, we thought it would be useful to go through the reasons why plant parents might want and need to propagate it. The main reason is simply wanting to multiply the number of plants you have without actually having to buy any more. Who can say no to free Calathea Triostar plants?! Calathea Triostar cuttings and young plants also make great gifts for friends and family.

The other main reason why plant parents might choose to propagate their Calathea Triostar is because their plant is becoming too big for the space and they need to prune it. But instead of simply throwing away those beautiful Calathea Triostar cuttings, why not propagate them and start a whole new mother plant. 

You might also end up not having a choice but to propagate your Calathea Triostar if it is showing signs of distress and unhappiness. We always recommend you try and figure out what is causing the issue but if nothing seems to be getting better then you might need to propagate part of the plant to save it. Just make sure that the part of the plant you are propagating is healthy as any issues will transfer onto the young new plant. 

What tools/equipment will I need to propagate a Calathea Triostar plant?

Let’s start off with the easy part. It’s important to make sure you have all the right things before you start propagating your Calathea Triostar


  • Healthy and mature Calathea Triostar plant

  • Sharp scissors/shears

  • Spare pot(s)

  • Fresh soil and water

  • Newspaper or plastic sheet if you’re propagating indoors

What methods can be used to propagate a Calathea Triostar?

Unlike most other houseplants, you can only propagate your Calathea Triostar through division of the mother plant. This can be a problem if you have quite a young plant and don’t want to take such a large chunk from it. But the good thing about the division method of propagation is that it’s very successful and much quicker. Your new plant will already have quite a mature root system which makes them more robust.

How to propagate a Calathea Triostar through division of the mother plant


  1. Take your Calathea Triostar out of its pot

    To be able to propagate your Calathea Triostar through division, you’ll need to locate the various natural sections of the plant. Carefully take your plant out of the pot, shaking off the potting mix around the root system.

  2. Locate the various offshoots in your plant

    When looking for a part of the plant to divide it will become very obvious if there are various offshoots on your Calathea Triostar. They will have a separate root system and growth will stem from the middle of each section.

  3. Separate the different sections 

    You should be able to carefully pull the various sections apart from each other. It’s ok if you have to slice around the plant a little to separate them but just make sure that each part of the plant has a substantial amount of the root system to aid a successful Calathea Triostar propagation.

    It’s at this point that you can choose how many new plants you want to create. It will depend on not only the size of your Calathea Triostar but on how big and bushy you want the plants to end up.

  4. Place in either water or fresh potting mix

    Pot the main mother Calathea plant back into its original pot (or downsize if you have taken a lot away from the plant as this will help stabilise it as well as reduce the risk of root rot too!)

    Now you need to decide whether to place the new plant(s) in water first or straight into potting mix. This will depend on the maturity of the root system. If your plant has quite strong roots then go ahead and pot it straight into potting mix. However, if you’ve damaged the roots whilst propagating, or feel they are quite underdeveloped then you might want to grow the plant in fresh water for a few weeks. 

    When potting into soil make sure to use a high-quality potting mix. This will ensure that your Calathea Triostar gets the right balance of nutrients. You also need to use fresh soil rather than reusing any from other plants. Bacteria and pests can linger in potting mix without you even knowing and this will transfer onto your new young Calathea Triostar.

  5. Continue normal Calathea Triostar care

    Now that your new Calathea Triostar plant is at home in its new pot, you can care for it as you would your other mother Calathea plant. If it’s in water first you want to refresh that water every couple of days before repotting into soil once the root system is stronger. 

Calathea Triostar Propagation FAQs

Whilst propagating your Calathea Triostar plant is quite simple as you’re propagating it through division rather than stem or leaf cuttings, it’s still important to understand the basics to make sure it’s a success. Below you’ll find all the answers to your Calathea Triostar propagation questions! 

Common problems you might face when propagating a Calathea plant

Propagating houseplants will always be a little unpredictable and you might well come across some issues along the way. But don’t fret, we have learnt the hard way to figure out what’s causing the problem as well as the best way to fix it. 

So that’s everything you need to know to successfully propagate your Calathea Triostar! It’s never an exact science and some divisions of the plant will take longer to grow new leaves than others. But with the right methods, care and environment you should have several thriving Calathea Triostar plants in no time.
