Introduction to Calathea: The Dancing Plant
Calathea is a tropical plant from the Marantaceae family, native to the rainforests of South America. It is called the dancing plant because of nyctinasty: during the day, it opens its leaves to capture light; at night, it raises and closes them like praying hands, hence the nickname prayer plant.
In the collection of indoor plants, you will find the current selection.
Calathea, belonging to the Marantaceae family, is native to the lush rainforests of South America, particularly Brazil. In nature, it grows sheltered beneath dense vegetation, in a humid environment with filtered light. This tropical origin is key to understanding its cultivation needs indoors.
But what truly makes Calathea special is its fascinating movement, a phenomenon known as nyctinasty. During the day, the leaves open to capture light, while at night they rise and close, almost like hands clasped in prayer. This circadian rhythm has earned it the nickname "prayer plant." Observing this movement is an almost magical experience, a constant reminder that your plant is alive and responsive to its surroundings. It is a silent dance that brings a sense of calm and connection with nature directly into your living room.
Beyond this unique characteristic, Calatheas are prized for the extraordinary variety and beauty of their foliage. Each leaf is a work of art, with patterns, stripes, and colors that look hand-painted. This guide will help you preserve and enhance this beauty, transforming plant care into a rewarding and successful experience.
Calathea Characteristics and Varieties
Calatheas are a vast genus, with dozens of species and cultivars characterized by patterned leaves and nocturnal movement. Among the most widespread varieties are orbifolia, with its large, round leaves; lancifolia, with elongated, wavy leaves; roseopicta, with cultivars such as 'Medallion' and 'Dottie'; zebrina; ornata; and makoyana, known as the peacock plant.
Calatheas are a vast and diverse genus, comprising dozens of species and cultivars, each with its own unique charm. Understanding their common characteristics and the distinctive traits of the most widespread varieties is the first step toward mindful care.
The Most Popular Calathea Varieties
Let's explore together some of the most beloved and sought-after varieties, perfect for adding a touch of style to your home:

Leaf Movement: Why Calathea Is Called a "Prayer Plant"
As mentioned, the movement of Calathea leaves is one of its most fascinating characteristics. This behavior is not merely a botanical curiosity, but has a precise biological function. In nature, this movement allows the plant to optimize the absorption of sunlight during the day and reduce water loss at night, conserving moisture.
At home, this daily spectacle creates a special bond between you and your plant. Seeing the leaves rise at sunset and reopen at dawn is a sign that your Calathea is healthy and following its natural rhythm. It is a small miracle of nature that repeats every day, bringing a sense of wonder and dynamism to your living space. This behavior is also a useful indicator of its health: if you notice that the plant stops moving, it could be a sign of stress or less-than-optimal environmental conditions.

Calathea Care: A Step-by-Step Guide
To care properly for Calathea, provide bright, indirect light, never direct sunlight; consistently moist but well-drained soil, using rainwater, distilled water, or demineralized water; high humidity; temperatures between 18 and 26 °C, never below 15 °C, away from drafts; well-draining potting soil, repotting every 1-2 years, and diluted fertilizer every 2-4 weeks from spring to the end of summer.
Caring for a Calathea may seem challenging, but with the right knowledge and a little attention, you will see that it is easier than you think. Follow this step-by-step guide to ensure your plant has everything it needs to thrive.
Ideal Light for Calathea
Calathea is a light-loving plant, but it does not like direct sunlight. Remember its origins: it grows in the understory of tropical forests, where light is filtered through the canopies of taller trees. Direct exposure to sunlight, especially during the hottest hours, can burn its delicate leaves, causing brown spots and faded colors.
The perfect location:
•Bright, indirect light: Place your Calathea in a well-lit room, but away from south-facing windows. An east- or west-facing window is ideal, as it receives the softer light of the morning or late afternoon.
•Filter the light: If you only have very sunny windows, you can use sheer curtains to filter the light and protect the plant.
•Watch for signs: If you notice that the leaves are losing their vibrancy and the patterns are becoming less defined, it could mean that the plant is receiving too much light. Conversely, if growth is stunted and the stems are stretching abnormally, it probably needs more light.
Watering Calathea: When and How
Watering is one of the most critical aspects of Calathea care. These plants like consistently moist soil, but they cannot tolerate waterlogging, which can lead to root rot.
The golden rules of watering:
•Check the soil: The best way to know when to water is to check the soil. Insert a finger about 2-3 cm deep: if it feels dry, it is time to water. If it is still moist, wait another day or two.
•Quality water: Calatheas are very sensitive to the minerals and chlorine in tap water, which can cause the tips of the leaves to turn black. Ideally, use rainwater, distilled water, or demineralized water. Alternatively, you can leave tap water in an open container for 24 hours to allow the chlorine to evaporate.
•Water thoroughly but not excessively: When watering, wet all the potting soil evenly until water begins to drain from the pot's drainage holes. Always empty the saucer to prevent the roots from remaining in contact with stagnant water.
•Seasonal frequency: In spring and summer, during the active growth period, Calathea will need to be watered more frequently, about once or twice a week. In autumn and winter, reduce watering, allowing the soil to dry out slightly more between waterings.
Humidity and Misting
Humidity is the secret to keeping a Calathea happy with glossy leaves. As these plants originate in tropical environments, they thrive in high humidity, typically between 50% and 70%. The dry air in our homes, especially in winter due to heating, is one of their main enemies and the most common cause of unsightly dry tips.
How to increase humidity:
•Misting: Mist the leaves regularly, even daily, with low-limescale water. This helps maintain local humidity and clean dust from the leaves.
•Humidifier: Using a room humidifier is the most effective solution for maintaining a constant, ideal humidity level for your plant.
•Expanded clay tray: Place the pot on a tray filled with expanded clay and a little water. The evaporation of the water will increase the humidity around the plant without the roots coming into direct contact with the water.
•Group plants together: Plants transpire and release water vapor. Grouping several plants close together creates a more humid microclimate that benefits them all.
Temperature and Placement
Calathea loves warmth and does not tolerate temperature fluctuations. The ideal temperature for its growth is between 18°C and 26°C. It is essential to avoid temperatures below 15°C, which can seriously damage the plant.
Where to place your Calathea:
•Away from drafts: Avoid placing it near doors, frequently opened windows, or air conditioning and heating vents. Drafts, both hot and cold, can stress the plant and cause the leaves to curl.
•Stable environments: The bathroom and kitchen, being generally more humid, can be ideal environments for a Calathea, provided they receive an adequate amount of light.
Potting Soil and Repotting
Good potting soil is essential for the health of a Calathea. It needs a well-draining substrate that can retain moisture and is rich in organic matter.
The perfect mix:
•Potting soil for green plants: High-quality potting soil for green plants is an excellent starting point. To improve drainage, you can add perlite or pumice.
•When to repot: Calatheas do not like being disturbed too often. Repot every 1-2 years, or when you notice that the roots have completely filled the pot and are coming out of the drainage holes. The best time to repot is spring, at the beginning of the growing season.
•How to repot: Choose a pot with a diameter slightly larger (2-3 cm more) than the previous one. Handle the root ball gently and place the plant in the new pot, filling the spaces with fresh potting soil. Water lightly after repotting to settle the soil.
Seasonal Fertilization
During the growing season, from spring to the end of summer, Calathea needs nutritional support to produce its magnificent leaves. Use a balanced liquid fertilizer for green plants, diluted to half the dose recommended on the label. Fertilize every 2-4 weeks after watering to avoid burning the roots.
In autumn and winter, stop fertilizing to allow the plant to enter its dormant period.
Common Calathea Problems and Solutions
The three most common Calathea problems are dry, brown tips, almost always caused by excessively dry air or hard water; yellow leaves, usually due to overwatering; and curled leaves, a sign of thirst or drafts. Less commonly, pests such as spider mites and mealybugs may appear, encouraged by dry air.
Even with the best care, Calatheas can sometimes develop problems. Learning to recognize the signals your plant is sending you is essential for taking timely and effective action. Here is a guide to the most common problems and their solutions.
Calathea Dry Leaves: Causes and Remedies
Dry, brown tips are the most common problem in Calatheas and are almost always related to a lack of humidity.
•Diagnosis: The leaf tips become dry, crispy, and brown. This can spread along the edges of the leaf.
•Cause: Excessively dry air is the main cause. Other causes may include using water that is too hard or calcareous, or over-fertilizing.
•Solutions:
1.Increase humidity: Mist the leaves daily, use a humidifier, or place the plant on a tray with expanded clay and water.
2.Check the water: Use rainwater, distilled water, or demineralized water for watering.
3.Reduce fertilizer: If you suspect excess fertilizer, stop fertilizing for a few weeks and flush the soil with plenty of water to remove excess salts.
Calathea Yellow Leaves: What to Do
Yellow leaves can signal several problems, but the most common is overwatering.
•Diagnosis: The leaves, usually the lower ones, begin to turn yellow and may feel soft to the touch.
•Causes: Too much water, which causes constantly waterlogged soil and the risk of root rot. Less frequently, it may indicate nutrient deficiencies or the end of the leaf's own life cycle.
•Solutions:
1.Moderate watering: Always check the soil before watering and make sure the top few centimeters are dry. Make sure the pot has good drainage.
2.Check the roots: If the problem persists, carefully remove the plant from its pot and check the condition of the roots. If they are dark, soft, and foul-smelling, root rot is occurring. In this case, remove the damaged roots with clean scissors, repot in fresh soil, and drastically reduce watering.
3.Balanced fertilization: If watering is correct, it could be a nutrient deficiency. Make sure to follow a regular fertilization schedule during the growing season.
Calathea Curling Leaves: Diagnosis and Care
Curling leaves are a clear sign of water stress.
•Diagnosis: The leaves curl in on themselves, losing their normal flat shape.
•Causes: The most common cause is thirst. The plant is trying to reduce the exposed leaf surface to limit transpiration and water loss. It may also be a reaction to excessively high temperatures or drafts.
•Solutions:
1.Water immediately: If the soil is dry, water the plant thoroughly. The leaves should return to normal within a few hours or at most a day.
2.Check the location: Make sure the plant is not exposed to direct heat sources or drafts.
3.Increase humidity: Air that is too dry can also contribute to this problem. Follow the advice for increasing ambient humidity.
Pests and Diseases
Although fairly hardy, Calatheas can be attacked by certain pests, especially under stressful conditions or in dry air.
•Red spider mite: These tiny mites thrive in warm, dry environments. They appear as small yellow spots on the leaves and, in more severe cases, as fine webs. To combat them, increase humidity and wipe the leaves with a damp cloth. In case of severe infestations, use a specific acaricide, preferably an organic one.
•Mealybug: They appear as small brown scale-like insects or cottony tufts, usually on the underside of leaves or where the stems meet. Remove them manually with a cotton swab soaked in alcohol, then wash the plant with Marseille soap. For extensive infestations, use a specific insecticide.
For any problem, remember that careful observation is the first step toward a correct diagnosis.

Calathea Propagation and Multiplication
Propagating your Calathea is an exciting experience that allows you to expand your plant collection or share the beauty of your plant with friends and family. The simplest and safest method for propagating Calathea is division of clumps.
Division of Clumps
This method should preferably be carried out in spring, at the same time as repotting, to reduce stress on the plant. Division consists of separating the mother plant into several sections, each with its own root system.
How to proceed step by step:
1.Prepare the plant: Water your Calathea the day before division to make the soil softer and the roots more flexible.
2.Remove the plant from the pot: Carefully remove the plant from its pot, taking care not to damage the roots. Gently shake off the excess soil to expose the root system.
3.Identify the division points: Examine the base of the plant and identify the natural clumps, namely groups of stems with their own roots. Each clump can become a new independent plant.
4.Divide the clumps: Gently separate the clumps with your hands. If the roots are very tangled, you can use a clean, sharp knife, making sure each new section has at least 2-3 leaves and a good number of healthy roots.
5.Repot the new plants: Plant each new section in an appropriately sized pot filled with fresh, well-draining soil. Do not compact the soil too much, so the roots can breathe.
6.Post-division care: After repotting, water lightly and place the new plants in a warm, humid location with indirect light. It is normal for the plants to show signs of stress for a few weeks. Maintain high humidity to help them recover more quickly.
Propagation from Cuttings
Propagation from cuttings is more complex for Calatheas and has a lower success rate than dividing the clumps. However, if you want to take on this challenge, here is how:
1.Take the cutting: Choose a healthy stem with at least two or three leaves and cut it just above the surface of the substrate.
2.Place it in water or soil: You can try rooting the cutting in water or directly in a small pot with moist soil and sand.
3.Create a humid environment: Cover the pot with a transparent plastic bag or place it in a mini greenhouse to maintain high humidity. Air it out occasionally to prevent mold from forming.
4.Be patient: Rooting can take several weeks. Once the cutting has developed a good root system and shows signs of new growth, you can transplant it into a larger pot.
Dividing the clumps remains the most recommended and rewarding method for propagating your Calatheas, ensuring a greater chance of success and new healthy plants to love and care for.
Calathea and Design: How to Decorate with Style
To decorate with Calathea, choose a proportionate pot with drainage holes, made of terracotta or glazed ceramic, in a color that contrasts with the leaves, and place it in the living room, bedroom, study, or a bathroom with a window, perhaps alongside ferns, Pothos, or Monstera to create an urban jungle corner.
Calathea is not just a plant; it is a true design element. With its spectacular foliage, it can enhance any space, from the most modern to the most classic. Here are some tips for incorporating your Calathea into your home decor.
Best Pots for Calathea
Choosing the right pot is essential to enhance the beauty of your plant and ensure its health. A pot is not just a container, but also a decorative furnishing accessory.
•Materials: Terracotta pots are an excellent choice because they are porous and allow the soil to breathe, reducing the risk of waterlogging. Glazed ceramic pots, available in an endless variety of colors and finishes, are perfect for creating color combinations with the plant's leaves.
•Colors: Choose a pot that creates an interesting contrast with your Calathea's leaves. A white or neutral-colored pot will highlight the intricate patterns of a Calathea ornata or medallion. A dark pot can create an elegant and sophisticated look with a Calathea zebrina.
•Size: Make sure the pot is proportionate to the plant and always has drainage holes in the bottom. Explore our selection of designer pots to find the perfect one for your Calathea.
Placement in the Home
Thanks to its tolerance of indirect light, Calathea is extremely versatile and can be placed in different areas of the home.
•Living room: A large Calathea orbifolia can become the focal point of your living room, placed near an armchair or sofa.
•Bedroom: A Calathea is perfect for the bedroom, where it helps create a relaxing atmosphere and purifies the air.
•Study or office: Adding a touch of greenery to your desk or a corner of your study helps reduce stress and improve concentration.
•Bathroom: If your bathroom has a window, it is the ideal environment for a Calathea, thanks to the natural humidity that develops there.
Pairings with Other Plants
Creating an "urban jungle" is one of the most popular trends. Grouping your Calathea with other houseplants not only creates a beautiful visual effect, but also helps increase local humidity. Pair it with plants that have similar needs, such as ferns, Pothos, or Monstera, to create harmonious and easy-to-manage arrangements.
Benefits of Calathea: Well-Being and Clean Air
Calathea offers two main benefits: it is non-toxic to dogs and cats (source: ASPCA) and helps improve indoor air quality because it absorbs carbon dioxide, releases oxygen, and filters some harmful substances such as formaldehyde and benzene.
In addition to their undeniable beauty, Calatheas offer numerous health and wellness benefits.
Calathea and Pets
One of the main concerns for people with pets is the toxicity of houseplants. According to the ASPCA, Calathea is not toxic to dogs and cats (source: ASPCA).
Air Quality Benefits
Like many other houseplants, Calathea is an excellent air purifier. Through photosynthesis, it absorbs carbon dioxide and releases oxygen. It can also filter some harmful substances in the air in our homes, such as formaldehyde and benzene, helping create a healthier, cleaner environment. Having a Calathea at home means breathing better air, a tangible benefit for the whole family.
Seasonal Care Calendar
In spring and summer, from March to September, Calathea needs bright but indirect light, watering 1-2 times a week, maximum humidity, and fertilizer every 2-4 weeks; it is also the time for repotting and division. In autumn and winter, from October to February, reduce watering, stop fertilizing, and check for pests.
To make caring for your Calathea even easier, here is a practical seasonal calendar with the main tasks to complete.
Spring-Summer Care (March - September)
