Calathea Plant:
Indoor Growing Tips for a Lush and Healthy Plant

Updated: April 24, 2023

The Calathea plant, also known as the prayer plant, is a popular houseplant that is loved for its beautiful foliage and easy maintenance. With its unique patterns and vibrant colors, this plant can add a touch of elegance to any room.

However, to keep your Calathea healthy and vibrant, there are a few things you need to know. In this article, we will provide you with some tips on how to grow your Calathea plant indoors for a lush and healthy plant.

Understanding the Calathea Plant

The Calathea plant belongs to the family Marantaceae and is native to tropical regions of South America. It is a low-growing plant that reaches up to 2 feet in height and has distinct patterns on its leaves.

The most striking feature of the Calathea is its ability to move its leaves up and down throughout the day. This phenomenon is called nyctinasty, which means that the plant’s leaves respond to light changes by folding or unfolding.

Light Requirements

Calathea plants thrive in bright, indirect light. They can tolerate low light conditions but will not grow as well. Direct sunlight can scorch their leaves, so it’s best to keep them away from windows that receive direct sunlight.

If you don’t have access to bright, indirect light, you can use artificial lighting. LED grow lights are an excellent choice for indoor plants and provide the right spectrum of light for your Calathea.

Watering

Calathea plants prefer consistently moist soil but do not like soggy roots. Overwatering can cause root rot, which can be fatal to your plant. To avoid this, make sure that your pot has drainage holes at the bottom so that excess water can drain out.

Water your Calathea when the top inch of soil feels dry to the touch. Water it thoroughly until water starts to come out of the drainage holes. Discard any excess water after 15 minutes.

Humidity

Calathea plants love humidity and thrive in environments with high humidity levels. If your home is dry, you can increase humidity by using a humidifier or placing a tray of water near your plants.

Misting your Calathea with water can also help increase humidity levels. However, make sure not to mist too much or too often as this can lead to fungal diseases.

Soil

Calathea plants prefer well-draining soil that retains moisture. A good potting mix for Calathea should contain peat moss, perlite, and vermiculite.

It’s also essential to repot your Calathea every two years or when you notice that its roots are starting to outgrow its pot.

Fertilizer

Calathea plants do not need much fertilizer but can benefit from occasional feeding during the growing season (spring and summer). Use a balanced fertilizer diluted to half strength every three weeks.

Avoid fertilizing during winter when the plant is dormant.

Common Problems

One common problem with Calathea plants is leaf curling. This can be caused by overwatering or underwatering, low humidity levels, or exposure to direct sunlight. Adjust watering habits and increase humidity levels if you notice leaf curling.

Another issue with Calatheas is yellowing leaves. This can be caused by overwatering or underwatering, pests, or nutrient deficiencies. Check for pests and adjust watering habits accordingly.

Conclusion

Growing a lush and healthy Calathea plant indoors requires proper care and attention. By understanding its light requirements, watering needs, humidity levels, soil preferences, and fertilizer requirements, you can ensure that your plant thrives in its environment.

Remember to keep an eye out for common problems such as leaf curling and yellowing leaves and make adjustments as necessary. With these tips in mind, you’ll be able to enjoy a beautiful and vibrant Calathea plant in your home.
