And by dying, most people tend to overreact to every little crispy leaf, but you can quickly kill a Calathea if you are not aware of a few things!

In this post, I will provide my personal experience with Calathea. In particular, I will show my Calathea lancifolia (also known as Rattlesnake Plant) and Calathea orbifolia.

However, the care and advice will apply broadly to all plants in the Calathea genus.

Some other gorgeous Calathea species include Calathea makoyana, Calathea ornata, and Calathea roseopicta, among many others!

I will go into the care very shortly, but let me show you my plants. Here is my Calathea lancifolia.

I absolutely love the stunning patterns on the leaves! And here is my Calathea orbifolia. These plants can grow HUGE. A friend actually sent me a tiny orbifolia in a mail and she is starting to grow into a beautiful specimen.

I would encourage you to read this entire post because you can’t really separate elements of houseplant care. You have to look at them all together to get a good picture of how to take care of your plants!

By the end of this post, you will understand how to care for your Calathea and how to do your best to keep them in great shape and minimize those crispy leaves and edges that plague many people.

HUMIDITY FOR CALATHEA

I wanted to start out first by talking about humidity. There are MORE important topics than humidity actually, but I will get to those very soon.

If you can provide higher humidity for your Calathea plants, please go ahead and do so. It is NOT the most important factor in keeping most of your Calathea species in good shape, but it can help.

First of all, misting will do nothing to increase humidity! Humidity is a measure of moisture in the air. You are just wetting the leaves by misting.

That being said, Calathea can be prone to spider mites and misting can actually help deter spider mites (since spider mites like very dry conditions). There is one benefit to misting!

However don’t expect misting to increase your humidity. There are better ways. If you do have a spider mite infestation, read my blog post on Spider Mites: 3 Things You Can Do to Stop Them.

Back to humidity. One great way to increase humidity for your Calatheas and other plants is to simply get a humidifier. I honestly only run mine in the winter time when our indoor air is super dry.

My absolute favorite humidifier, and the one that I personally use is the Levoit Humidifier. It honestly is the best one I’ve used and I’ve used a lot.

It will cost a little more but is well worth it. It has many features including cool and warm mist, and is quiet and very effective. Not to mention it is built very well and will last you much longer if you take care of it!

I run it all winter long in my sunroom. Not only is it good for my plants, but it is also great for my dry skin and my dry winter nasal passages! 😀

Another way to increase humidity is to group plants together. Plants naturally release water into the air by a process called transpiration. The more you group together, the more the localized humidity will increase.

I’ll stop now about humidity so if you want to read more, I’ll refer you to my How to Increase Humidity for Houseplants blog post.

WATERING CALATHEA

There are no secrets in houseplant care. A lot of people ask me frequently “what is your secret” for taking care of [insert plant of the day here].

The only “secret” is just proper houseplant care techniques, like proper watering. If you have proper watering down, in conjunction with proper light, you are most of the way there in ensuring that your plants are healthy.

Those dreaded Calathea crispy leaves and edges, more times than not, are due to inconsistent watering and/or improper watering! NOT humidity.

Proper watering is a much bigger factor in ensuring that your Calathea leaves are in great condition. If you have good humidity on top of all that, all the better! Think of it as a bonus.

You must get your watering practices down and have proper light first. THEN focus on increasing humidity. If you have all 3, you are golden.

That being said, PROPER AND CONSISTENT WATERING is the key to avoiding excessive crispy and brown leaf edges in Calathea (and other plants!)

Take my Calathea lancifolia plant above. This plant was in great condition for a long time when I was very attentive and consistent in watering.

But sometimes, something called life happens, and I either get too tired or busy and I let my plants dry out more than I normally do. If you keep doing this over and over, you will get crispy leaves.

Your Calathea is not dying if you have one crispy leaf. Keep that in mind. But neglect watering over and over again, and it just may die!

So how much do Calathea like to be watered? How often should you water your Calathea? The short answer is that it DEPENDS!

People ask me all the time how often to water plants. And it really just depends. Don’t go by your calendar!

Go by your soil moisture instead! Everyone’s conditions are different. The size of your pot, the type of pot you have (terra cotta vs. plastic for example), the temperature, type of soil, all play a role in how quickly the soil dries out.

So forget that calendar schedule for watering and use your finger instead. Calathea plants like to be on the moist side, but they do NOT like to dry out completely.

Calathea lancifolia

A good rule of thumb that I like to use for these plants is to allow the surface of the soil to dry out, and then water again. Maybe the top inch or so smaller pots. If you have a huge pot, maybe allow the top 2 inches to dry out.

But when do you water, water thoroughly! Let all the water drain out of the drainage hole, and you are done.

Then just keep observing and repeat. It really is as simple as that! By having good watering practices and never allowing your Calathea soil to completely dry out, you will avoid those ugly crispy and brown leaves.

On the other end, make sure that your plant is never sitting in watering for extended periods of time and always ensure that you have a drainage hole. Like most plants, you can have root rot if this continues.

Once you have root rot, you can start to get yellow leaves and also brown tips as well.

You may still get very small brown tips on the leaves even with good care, but seriously…don’t stress about those. As long as the rest of the plant looks healthy and vigorous, you have come a long way!

CAN CALATHEA GROW IN LOW LIGHT?

This is a loaded question too! Let me talk a little about “low light” and what Calathea like.

Low light is just too vague and everyone interprets it differently. Let me just tell you what works for me.

Calathea are among the “lower” light plants if you would like to call them that, but they still need to be in front of a window for best results. And by in front of a window, I mean within a couple feet (in most cases).

Light intensity decreases DRAMATICALLY the further you get from a window. You would be shocked!

Calathea do not like a lot of direct sun. The most I would do is some morning sun (which Eastern windows provide) but no more than that. Northerns windows will work well.

If you have any windows that are very sunny, you can either move your plant back a little, or use a sheer curtain to diffuse the direct sun so that the plants are not getting direct sun on their leaves.

Too much direct sun, or even short periods of hot, intense sun, can burn their leaves.

That’s it! You’re most of the way there now. Giving your Calatheas proper light and proper watering will go a long way in ensuring a beautiful plant.

There is more to consider though that is very important so keep on reading!

WHAT KIND OF SOIL DOES CALATHEA NEED?

Plants can really grow in a variety of mediums and soil mixtures, but the most important thing that you need to keep in mind is that the soil should be well drained.

There is no one “magic” soil mixture.

Many pre-packaged soil mixes can use some help though in the area of drainage!

As a general potting mix, I love using Miracle Gro potting mix and I do amend it a bit to make it fluffier and lighter, depending on what plants I’m growing.

For Calathea, I like to add perlite to mix.

I like to use my wheelbarrow outside for this to keep the mess down and keep it easy! My ratio will vary, but 2 to 3 parts of Miracle Gro potting mix to 1 part of perlite is a good rule of thumb!

The reason that you want good drainage all has to do with oxygen to the roots. If you incorporate things like perlite, which I buy often all the time from Amazon, it will increase drainage and oxygen to your plant’s roots.

This is very important for all plants.

Just mix everything together well and you are good to go. That being said, let’s talk about how to repot Calathea now.

CALATHEA REPOTTING

Are you ready to repot your Calathea? How do you know when to repot Calathea, or any other plant for that matter?

Has your plant been in that same small pot for a long time? You can simply slip your plant out of its pot to see if it is root bound. If it is, it is time to repot.

Maybe you see roots coming out of the drainage holes. Time to repot.

Or maybe you just have a lot of surface roots, and the pot just seems to dry out really quickly. Much more quickly than before.

These are all indications that you may want to repot.

Let’s take a look at my steps that I used to repot my Calathea lancifolia. This applies to almost all houseplants.

If you have a flexible plastic pot, you can just squeeze the pot gently to loosen it so you can take it out. I had mine in a ceramic pot so I just used a metal chopstick and passed just inserted it around the whole perimeter of the plant.

You can also use a knife to do this as well. Once you do this, gently see if the plant comes out of the pot. If it doesn’t, keep using the chopstick or knife until it does.

You can see from the photo above that it is pretty potbound. It could be worse though!

Then the next thing you want to do is to loosen the root ball. Gently take both hands and loosen the bottom and the sides of the rootball.

If you break a couple roots, please don’t worry. This step is necessary! Your plant will thank you!

If you don’t do this step, your plant’s roots will find it much more difficult to grow into the new soil in your new pot.

Once I had a peace lily that I didn’t do this do, and years later when I repotted it again, none of the roots had grown into the new soil! The original pot-bound look was still in-tact!

I ended up combining two plants into one pot. When you add your soil mixture, be sure that there are no air gaps. You want the roots to have contact with the new soil.

Gently press down to ensure that this occurs. Then give your plant a good watering, and you are done!

That’s all folks! Do you have any Calathea? What is your experience in growing them? Please comment below. I’d love to hear!
