How to Propagate Calathea Plants (Essential Tips)

If you’re a houseplant fan, there’s a good chance you’ve noticed a Calathea before. Also called prayer plants or rattlesnake plants, these tropical beauties feature dark foliage with bright splashes of red, yellow, or silver in various patterns. Not only are Calathea plants relatively easy to grow compared to some tropical plants, but they’re also fun to propagate. In this guide, we’re going to take you step-by-step through how to propagate a calathea plant at home.

How to Propagate Calathea Plants – The Essentials

Calathea plants aren’t propagated the traditional way, but rather through division. This is as simple as cutting a mature plant in half, ensuring both sides have plenty of roots and leaves. Pot cuttings in a rich, well-draining soil mix and leave in a warm, humid environment for 3 to 4 weeks to allow the cutting to root.

Can all Calathea Plants be Propagated? 

All plants in the Calathea genus, and even the larger Marantaceae family, can be propagated professionally. However, this doesn’t mean they will all succeed when propagated at home. Some varieties need special handling or hormones to trigger rooting and will be more challenging than others to turn into healthy new plants at home. Technically, Calathea plants aren’t propagated in the same way as other houseplants.

Key Considerations When Propagating a Calathea Plant

Can you propagate Calathea plants from seed, cuttings, leaf, other?

Unlike succulents and many other popular houseplants, Calathea plants are not propagated by taking a cutting. Cutting off a leaf from one of these plants and sticking it in soil, even with a lot of stem intact, will only lead to a dried up leaf. There’s no chance of a chunk of stem or root growing into a whole plant either. And unlike some houseplants, Calathea doesn’t flower readily enough to collect seed. 

Instead, you use a technique known as division. It’s one of the simplest ways to multiply plants and can feel a little extreme or aggressive. However, it’s reliable and easy for homeowners to do. 

You shouldn’t attempt to divide a Calathea unless you are comfortable with the risk of losing it since it will stress the entire plant.

Can Calathea Plants grow in Water and/or Soil?

Calathea plants don’t thrive in pure water, even when being propagated. Keep them in soil no matter what to ensure the roots don’t dry out or become waterlogged and begin rotting. 

There’s no need to place the Calathea you are dividing into water to protect it from shock while performing the division.

How to Propagate a Calathea Plant:

Division may be the only propagation method available for this genus of houseplants, but it’s a relatively easy technique to learn. There’s no need for making special cuts or building humidity chambers to control the conditions around the new plant. 

With a little care and a sharp hand trowel, you should have two Calathea plants where you had only one.

1. Select only mature, healthy plants near full size for division. Plants that are still growing eagerly may be shocked by division rather than encouraged by it. A mature Calathea’s size depends on the specific variety, but most top out around two or three feet in height.
2. Find a work area like a table or section of the garage floor that is flat and has good lighting. Cover the surface with newspaper or a small tarp so you can easily get all the spilled soil up when you are done.
3. Gently tip the plant over onto its side, arranging the foliage, so none of it is crushed. Slide the container or pot off of the plant’s roots, twisting if necessary to loosen it first. Soil will spill out, but most of it should remain bundled in with the roots. If the Calathea doesn’t have a strong and healthy-looking root mass with cream to white colored roots, consider avoiding division until it recovers.
4. Sit the plant up on its root ball as best it will balance. Look over the entire plant and try to draw a mental line between the two new plants. Each new plant will need close to half of the root ball and at least three to four strong healthy stems with foliage. Making divisions smaller than half of a mature plant is likely to end in failure.
5. Start dividing the roots a little by hand from the bottom of the root ball. Depending on the thickness of the roots and how bound they are, this may or may not be possible.
6. Using a sharp hand trowel, begin cutting from the top of the soil downward to divide the two plants as you’ve decided in step 4. Stop and regularly check to ensure you’re aligned with any divisions in the root ball you already made by hand. Work slowly and carefully. It’s pretty physical work, so you may need a sharp kitchen knife or garden knife to sever the thickest parts at the center of the root mass. Try to avoid damaging the foliage as you roll the plant around to access its roots.
7. Once the two halves of the plant are separate, place each one in a container that is just ½ inch larger than its new root mass. Fill in around it with a loose, fast-draining soil mix that isn’t highly fertilized. Newly divided plants are sensitive to nutrients and need a neutral base to start growing in. Tamp down the soil gently, and water well until all of the soil mix is saturated. Keep the divided plants well-watered for the first few weeks since they won’t have the extensive root system to keep themselves hydrated.

Post Propagation Care

Let the newly divided Calathea plants stay in a warm, humid environment for the first few weeks as they recover from the shock. 

Keep light levels low but consistent. The plants may initially show signs of shock, such as wilting or drooping, and browning of the leaves. Avoid overwatering at that point in response. This would be similar to re-potting a calathea plant.

Let the plants slowly recover and keep conditions correct, and you’ll eventually see them perk up. Color loss may be permanent on stressed leaves, but new foliage will soon replace them.

In addition, keep an eye out for any common calathea plant pests, bugs, and diseases.

Growth Expectations

Even with proper handling, a Calathea division is likely to stay stunted and shocked for a few months after this process. That doesn’t mean it’s not going to grow. After three to four months, the plant may suddenly surprise you with a growth spurt. 

The plant will begin growing in earnest again with new foliage at whatever point the roots are established enough. Divided plants generally resume normal Calathea growth rates within six months and can reach the size of the original plant within two to three years after that. 

Dividing a larger plant from the start will shorten the time it takes for the divisions to reach full size.

Wrapping Up

Calathea plants are fun to propagate because you either get new plants for free or gifts to give to friends. Try giving your mature Calatheas a division to see how they respond with new growth.
