How to Care for Calatheas

Are you considering investing in prayer plants known as the Calathea, wondering if it is an easy plant to care for?

Then you have reached the right place as we have a general care guide here to learn about these unique tropical plants.

Why is the care for most of the different species quite similar? Nonetheless, you may find that some Calathea plants are a bit more demanding than others.

What are Calathea Plants?

Calathea plants, known as prayer plants, are loved for their beautiful foliage. The plant has bold marks with an array of colors on the oblong leaves. The genus is one of the most stunning tropical plants found.

The eye-catching stripes with detailed veining give it a nickname of being the zebra plant, rattlesnake plant, or peacock plant but also referred to as the prayer plant. Yet, you will find many other species going by the same name.

The Calathea you can find growing outside their typical environment of Africa, but they are not cold-hardy plants. Hence, you typically grow them indoors. The zebra plants belong to the Marantaceae family, herbaceous and perennial.

While they seldom bloom indoors, you have exceptions like the Calathea crocata. As a mature plant, the peacock plant can reach up to two feet tall in a year.

Prayer Plant Care

Prayer plants are a bit fussy and grown as indoor plants. The reason is that when you care for Calathea, they need specific needs, and you cannot neglect them. Still, they can thrive as outdoor plants when in their natural environment.

It can flourish with proper care as an indoor plant by mimicking its climate. A big note is that peacock plants are susceptible to cold drafts. But the best part is they do not take up much space. You can place your Calathea plant in any room close to a bright window away from heat/cooling vents.

Still, the best place is the bathroom because of the humidity requirements.

Prayer Plants Preferred Soil Mix

For many plants in the Marantaceae family, moist, rich soil is essential, and it helps to use a blend that can retain water while allowing excess water to drain freely. Unfortunately, the Calathea plant is very susceptible to root rot.

So, the peaty potting mix works well as it is lightweight yet airy and made for your African violets that are just as fussy. Alternatively, you can make a mixture of 2:1 soil-based compost with some perlite.

Bright Indirect Light for Calathea Plants

While you may think that growing in Africa, prayer plants prefer direct sunlight; it is not the case. The tropical plant grows in a humid environment with indirect light. The Calathea plant can even grow in low light.

Too much light can result in the leaves burning, and those vibrant patterns will start to fade. So, the best place for indoor spaces is in an east, west, or south-facing window. It also helps to rotate your plant in lower light allowing the sun to reach it evenly.

You will also notice movement in the leaves throughout the day, and at night the leaves close up as if in prayer. The plant does this to maximize the sun’s absorbency.

How Often to Water Indoor Plants

As much as you need to avoid direct sunlight, the root system of most plants in the Calathea genus remains thirsty. So the soil needs to stay moist but not soggy. You can often water to prevent leaving the soil dry.

If you notice brown edges on the leaves or it is withering, it is a sign your plant needs water. Water Calathea plants with filtered or distilled water as they are picky about what they drink. Tap water has more chemicals than distilled water that can turn the leaves yellow.

We also recommend leaving the tap water outside overnight for the chemicals to evaporate. Another important note is to allow the excess moisture to drain through the drainage hole and throw it out to prevent your plant from sitting in water.

Fertilizing Your Calatheas

If you want a luscious plant, it helps feed your beauty at least once a month using a liquid fertilizer diluted to half strength. You can do this in spring, summer, and fall. Still, hold off from feeding in the winter months as your Calathea grows less.

Temperature and Humidity Level Needs

The light requirements must be suitable to keep your Calathea happy, but it also needs high humidity. So if you are concerned that the moisture levels are incorrect, it helps to keep a humidifier nearby to your plants.

Or you can fill a tray with pebbles and water, filling it up without it touching the pot. Another great option is a terrarium to create the right humid conditions. For Calathea’s care, temperature also plays a huge part.

The spot you choose must be toasty in temperatures ranging from 65°F to 80°F. The temperature can drop to 60°F but not below. Another helpful thing is to keep your Calathea away from cold drafts or excessive heat.

During the summer, you can leave your plants outside if the temperature does not drop below 60°F at night, and the climate is best if it has higher humidity levels. Also, it helps provide them with the exact light requirements indoors.

The important thing is that your Calathea must not receive direct sun and provide moist soil at all times. If your Calathea does receive rainfall, you can skip the watering. When you notice a temperature drop, bring your Calathea inside.

Pruning and Maintenance

One fantastic thing is that your Calathea does not prune much. You only do this when you need to remove brown leaves or the ones that naturally die. Then, with a trim, it keeps your indoor plant looking tidy as the Calathea’s leaves fall off by themselves.

For repotting, you can expect to do this every few years, but your Calathea must not become root bound as it can lead to fungal infections. The best time to repot your baby in spring and summer, the active growing season.

It helps to water the pot a day or two before the time to help lessen stress on your prayer plants.

Propagating Calathea Plants

The best way to propagate your Calathea is through division, done in spring or summer when repotting.

  1. Water your Calathea the day before to help reduce stress making it easier to remove it from the container.

  2. Prepare a new pot with enough drainage holes and fill it 1/3 with 2/3 peat moss mixed with 1/3 perlite.

  3. Tip your Calathea on its side to help it slide out of the container and brush away the soil to separate the root ball.

  4. Then look for a natural division to carefully separate the roots. Work the roots free using your fingers.

  5. Trim any damaged roots and divide them into two sections.

  6. Now, plant each division into a new pot and fill it with soil to the same level on your Calathea.

  7. Water your Calathea and offspring with filtered water to keep in moisture but not soggy.

  8. Next, cover the pot with a clear plastic bag until you notice new leaves growing.

  9. But keep opening the bag to allow fresh air into the bag and remove it when new growth begins.

Another concern is leaf spots resulting from tap water, which can also be a fungal infection. While brown spots and edges due to humidity or watering using tap water. On the other hand, yellow leaves can result from age, or if more leaves turn yellow, it can also be from overwatering.
