How To Save a Dying Calathea Plant (11 Causes & Solutions)

A Calathea plant, commonly known as the prayer plant, is a beautiful, low-maintenance houseplant that offers a splash of greenery to any indoor space. But, like all plants, they are susceptible to problems occasionally.

There are several reasons why your Calathea plant may be dying.

But how to save a dying calathea plant?

This article will guide you through some of the most common causes of a dying Calathea plant and what you can do to save it.

Why Is My Calathea Dying?

There are several reasons why your Calathea plant may be dying.

The first step to saving your plant is to identify the problem so that you can take the appropriate steps to fix it.

Here are some of the most common reasons why a Calathea plant may be dying and what you can do about it:

1. Overwatering

Overwatering is one of the most common reasons a Calathea plant dies.

Calathea plants are native to tropical rainforests and grow in moist, humid conditions.

However, they do not like to be waterlogged and will quickly start to die if they are overwatered.

Overwatering often occurs when the pot does not have drainage holes or the plant is left sitting in water.

How To Tell If You Are Overwatering Your Calathea

There are several signs that you are overwatering your Calathea plant.

These include:

• The leaves are wilting or drooping
• The leaves are turning yellow or brown
• The leaves have brown or black spots or blotches
• The leaves are curled or wrinkled
• The stems are soft or mushy
• The roots are black or rotten
• The soil is soggy or waterlogged

How To Save An Overwatered Calathea

If you think you may have overwatered your Calathea plant, the first step is to stop watering it.

Allow the soil to dry out completely before watering again.

You may also need to repot your plant into a pot with drainage holes to help reduce the risk of overwatering in the future.

You must also prune your plant to remove any damaged or dead leaves.

It’s essential to check the roots of your plant to see if they have started to rot. If they have, you will need to cut away any affected roots and repot the plant into fresh, dry soil.

2. Underwatering

Underwatering is another common reason why a Calathea plant may start to die.

Calathea plants need regular watering to keep the soil moist but not soggy.

If the soil is allowed to dry out for long periods, the plant will start to suffer.

Calathea plants need to be watered at least once a week and more often in hot weather.

How To Tell If You Are Underwatering Your Calathea

There are several signs that you are underwatering your Calathea plant.

These include:

• The leaves are wilting or drooping
• The leaves are crunchy and dry

If you think you may have underwater your Calathea plant, the first step is to start watering it more regularly.

Water the plant at least once a week and more often in hot weather.

To help bring your plant back to life, water it deeply and let the soil dry out completely before watering again.

You should also increase the humidity around your plant by misting it regularly or using a humidifier.

3. Too Much Sunlight

Calathea plants need bright, indirect sunlight to thrive.

If they are exposed to direct sunlight for long periods, the plant leaves will scorch and turn brown.

Calathea plants are also sensitive to changes in light and will start to suffer if they are moved around too much.

They need at least six hours of bright sunlight daily to stay healthy.

How To Tell If Your Calathea Is Getting Too Much Sunlight

There are several signs that your Calathea plant is getting too much sunlight.

These include:

Mixing in some perlite or sand is the best way to do this.

This will help to improve aeration and drainage.

You can also try planting your Calathea in a pot with drainage holes.

Make sure the pot you choose is not too big, as a pot that is too large will hold too much water and cause the roots to rot.

It is also essential to make sure you are not overwatering your plant.

Allow the soil to dry out between waterings to prevent root rot.

6. Root-Bound

Calathea plants need room to grow and will become root-bound if planted in a pot that is too small.

A root-bound plant will have a mass of roots that fill the entire pot and start to crowd each other.

This can cause the plant to suffer as the roots will not be able to absorb the nutrients and water they need.

This will help to remove any excess fertilizer from the soil.

After flushing the soil, do not fertilize your plant for at least a month.

Calathea plants are also sensitive to chemicals and toxins in the environment.

If you think your plant has been exposed to chemicals, it is best to flush the soil and rinse the leaves with water.

10. Pest Infestation

Calathea plants are susceptible to various pests, including mealybugs, spider mites, and scale.

These pests can cause severe damage to your plant and may even kill it if they are not removed.

Mealybugs, tiny white insects, feed on plant sap and may lead to yellowing and eventual leaf loss in Calathea plants.

Spider mites, diminutive arachnids, typically appear in red or black color and create intricate web structures beneath leaves. Their sustenance primarily relies on the act of piercing leaves and extracting sap from plants.

Spider mites can cause your plant’s leaves to turn yellow, brown, and crispy.

Scale insects are small, brown, or black insects that attach themselves to the stems of plants.

They feed on the plant by sucking out the sap.

Scale can cause the stems of your plant to turn yellow and eventually die.
