Calathea: How to Grow and Care for Calathea Plants Indoors
Calatheas, often referred to as prayer plants, are popular houseplants known for their stunning foliage and vibrant patterns. These tropical beauties can thrive indoors if you provide them with the right care. This guide will help you understand how to grow and care for Calathea plants indoors, ensuring they remain healthy and beautiful.
Understanding Calathea Plants
Calatheas belong to the Marantaceae family, and they are native to the tropical regions of the Americas. They are known for their decorative leaves, which can feature a variety of colors and patterns, including stripes, spots, and even purple undersides. These plants are often called “prayer plants” because their leaves fold up at night, resembling hands in prayer.
Popular Varieties of Calathea
Calatheas come in many varieties. Here are some of the most popular ones you might consider for your home:
- Calathea ornata: Known for its pink-striped leaves, it adds a touch of elegance to any space.
- Calathea lancifolia: Also called the Rattlesnake plant, this variety features long, wavy leaves with dark spots.
- Calathea makoyana: The Peacock plant has leaves with intricate patterns resembling a peacock’s tail.
- Calathea roseopicta: Known as the Rose-Painted Calathea, it features dark green leaves with a pinkish hue.
Benefits of Having Calathea Indoors
Calathea plants are not only beautiful but also beneficial:
- They improve indoor air quality by filtering toxins and releasing oxygen.
- Their vibrant colors and patterns can enhance the aesthetic appeal of your home.
- Calatheas are non-toxic to pets, making them a safe choice for households with animals.
Essential Growing Conditions for Calathea
Calatheas require specific conditions to thrive indoors. Here’s what you need to know:
Light Requirements
Calatheas prefer indirect light. Direct sunlight can scorch their leaves, while too little light can cause the vibrant colors to fade. Place your Calathea in a spot where it receives bright but filtered light, such as near a north or east-facing window.
Temperature and Humidity
These tropical plants thrive in warm, humid conditions:
- Maintain a temperature between 65°F to 80°F (18°C to 27°C).
- Avoid cold drafts and sudden temperature changes.
- Provide humidity levels of at least 50% or higher. You can use a humidifier or place a pebble tray with water near the plant.
Watering Needs
Proper watering is crucial for Calathea care:
- Keep the soil consistently moist but not soggy. Overwatering can lead to root rot.
- Use distilled or rainwater, as Calatheas are sensitive to fluoride and other chemicals in tap water.
- Allow the top inch of soil to dry out slightly before watering again.
Choosing the Right Soil and Potting
Selecting the appropriate soil and pot is important for healthy Calathea growth:
Soil Mix
Calatheas prefer a well-draining potting mix that retains moisture. A mix of peat, perlite, and regular potting soil works well. The peat helps retain moisture, while the perlite improves drainage.
Choosing the Right Pot
Ensure your pot has drainage holes to prevent waterlogging. You can use a plastic or ceramic pot, but make sure it allows excess water to escape.
Fertilizing Calathea Plants
Feeding your Calathea can promote vibrant growth:
- Use a balanced, water-soluble fertilizer every four to six weeks during the growing season (spring and summer).
- Reduce feeding during the fall and winter when the plant’s growth slows.
- Be cautious not to over-fertilize, as it can lead to salt buildup and damage the plant.
Pruning and Maintenance
Regular maintenance keeps your Calathea looking its best:
Pruning Tips
- Trim away any dead or yellowing leaves to encourage new growth.
- Use clean, sharp scissors to make clean cuts and prevent infection.
Cleaning the Leaves
Dust can accumulate on the leaves, affecting the plant’s ability to photosynthesize. Wipe the leaves gently with a damp cloth to keep them clean and shiny.
Common Problems and Solutions
Knowing how to identify and address common issues can keep your Calathea healthy:
Leaf Curling
Leaf curling often indicates underwatering or low humidity. Make sure you’re providing enough water and humidity for the plant.
Brown Leaf Edges
This can result from low humidity or the use of tap water with high mineral content. Increase humidity and consider using distilled water.
Pests
Calatheas can be susceptible to spider mites and mealybugs. Regularly check your plant for pests and treat infestations with insecticidal soap or neem oil.
Repotting Calathea
Repotting helps refresh the soil and gives roots more space to grow:
When to Repot
Repot your Calathea every two years or when you notice roots growing out of the drainage holes.
How to Repot
- Choose a pot one size larger than the current one.
- Carefully remove the plant from its old pot, being gentle with the roots.
- Place the plant in the new pot and fill with fresh soil mix, ensuring the root ball is covered.
- Water thoroughly and place the plant in its usual spot.
Propagating Calathea
Propagation is a great way to expand your Calathea collection:
Division Method
The best way to propagate Calathea is through division:
- Carefully remove the plant from its pot and gently separate the root ball into sections, ensuring each section has roots and leaves.
- Plant each section in a separate pot with fresh soil.
- Water well and keep in a warm, humid environment until the new plants establish.
Remember, Calatheas can be a bit finicky, but with the right care, they can thrive indoors and bring beauty to your space. Enjoy nurturing these lovely plants and watching them flourish!

Frequently Asked Questions
What are the ideal lighting conditions for Calathea plants indoors?
Calathea plants thrive in bright, indirect light. Direct sunlight can cause their leaves to fade or develop brown spots. It’s best to place them near a window with filtered light or in a room with ample natural light but away from direct sun rays. If your space doesn’t receive enough natural light, you can use fluorescent lights to provide the necessary brightness without harming the plant.
How often should I water my Calathea plant?
Water your Calathea plant when the top inch of soil feels dry to the touch. These plants prefer consistently moist soil but do not like to sit in water, as this can lead to root rot. During the growing season (spring and summer), you may need to water more frequently, while in the dormant months (fall and winter), watering can be reduced. Always ensure your pot has good drainage to prevent water accumulation.
What type of soil is best for Calathea plants?
Calathea plants prefer well-draining, peat-based potting soil. A mix that retains moisture yet allows excess water to drain away works best. You can create an ideal mix by combining regular potting soil with some perlite or orchid bark to improve aeration and drainage. Avoid heavy soils that retain too much water, as these can lead to root rot.
How do I maintain humidity levels for my Calathea plant?
Calathea plants thrive in high humidity environments, typically above 50%. You can maintain humidity by misting the leaves regularly, placing a humidifier nearby, or setting the plant on a tray filled with water and pebbles. Grouping plants together can also create a microclimate with higher humidity levels. Avoid placing your Calathea near air vents or in areas with dry air.
What are the common pests and how can I manage them on Calathea plants?
Common pests that affect Calathea plants include spider mites, aphids, and mealybugs. You can manage these pests by regularly inspecting your plants and wiping the leaves with a damp cloth. For more severe infestations, treat the plant with insecticidal soap or neem oil. Ensuring proper humidity and care can also prevent pest infestations, as healthy plants are less susceptible to pest problems.
Final Thoughts
Caring for Calathea plants indoors requires attention to light, humidity, and watering. Ensure they receive bright, indirect light and maintain high humidity to keep their leaves vibrant. Water them with distilled or rainwater to avoid leaf damage from minerals in tap water.
With proper care, Calathea plants can thrive indoors, adding lush, decorative foliage to your space. By following the guidelines in “Calathea: How to Grow and Care for Calathea Plants Indoors,” you can enjoy the beauty of these tropical plants. Keep an eye on their environment, and they’ll reward you with their stunning leaf patterns.
