The Calathea, often called the Prayer Plant (though technically different from Maranta), is one of the most stunning tropical houseplants you can grow. Known for its striking foliage marked with unique patterns and its fascinating habit of folding its leaves at night, the Calathea is a true showpiece in any indoor garden.
While beautiful, Calathea plants are also known for being a little “fussy.” They require the right balance of light, water, humidity, and soil to flourish. With proper care, however, they reward you with vibrant leaves and graceful movement that brings life to your home.
Here’s a complete care guide to help your Calathea thrive like it’s growing in its native tropical environment.

🌞 Light Requirements
These plants prefer bright, indirect light.
- Ideal spot: Place near a north- or east-facing window, or use sheer curtains to filter sunlight.
- Avoid direct sunlight: Harsh rays can bleach or scorch the delicate leaves.
- Low light: They tolerate lower light levels better than many houseplants, but growth will be slower.
👉 Pro Tip: If your Calathea’s colors start fading, it may need more indirect light.
💧 Watering Needs
Watering is critical to keeping this plant happy.
- Soil moisture: Keep the soil consistently moist, but never soggy.
- Check the top inch of soil: Water when it feels dry to the touch.
- Use the right water: Calatheas are sensitive to chemicals in tap water (especially fluoride). Use filtered, distilled, or rainwater whenever possible.
- Seasonal watering: Water more often in spring and summer, less in fall and winter.
⚠️ Warning: Crispy leaf edges often mean low humidity or water quality issues.
🌱 Best Soil for Calathea
Calatheas prefer a light, airy, and well-draining soil mix that retains moisture.
- A blend of peat moss or coco coir + perlite + orchid bark works well.
- Soil should hold moisture without becoming compacted.
- Slightly acidic to neutral pH (6.0–7.0) is best.
🌡️ Temperature & Humidity
Being tropical natives, Calatheas thrive in warm, humid conditions.
- Temperature range: 65–80°F (18–27°C).
- Avoid drafts, cold air, or sudden temperature changes.
- Humidity: 50% or higher is essential. They love humidity trays, regular misting, or placement near a humidifier.
👉 Low humidity is one of the main reasons Calatheas struggle indoors.
🌸 Fertilizing
Calatheas are not heavy feeders but appreciate light fertilization.
- Use a balanced, diluted liquid fertilizer (10-10-10 or similar) every 4 weeks during spring and summer.
- Avoid over-fertilizing, as it can cause leaf burn.
- Skip feeding in fall and winter when growth slows down.
✂️ Pruning & Maintenance
- Trim yellow, brown, or damaged leaves regularly.
- Wipe leaves with a damp cloth to remove dust and allow better photosynthesis.
- Rotate the plant every few weeks for even growth.
🌱 Repotting Calathea
These plants like slightly snug pots but benefit from fresh soil.
- Repot every 1–2 years in spring.
- Use a pot with drainage holes.
- Refresh soil annually to maintain aeration and nutrients.
🌿 Propagation
Propagation of this plant is done by division.
- Remove the plant from its pot during repotting.
- Gently separate clumps with healthy roots.
- Replant divisions in fresh soil.
- Keep humidity high until new growth appears.
⚠️ Common Problems & Solutions
- Brown leaf tips or edges: Low humidity or poor water quality. Increase humidity and use filtered water.
- Yellowing leaves: Overwatering or poor drainage. Let soil dry slightly between watering.
- Curling leaves: Underwatering, low humidity, or too much light. Adjust conditions accordingly.
- Pest issues (spider mites, aphids, mealybugs): Wipe leaves with neem oil or insecticidal soap.
🌟 Why Grow Calathea?
- Ornamental beauty: Eye-catching patterns and movement make it a centerpiece plant.
- Pet-friendly: Unlike many houseplants, this plant is non-toxic to cats and dogs.
- Air purifier: Helps filter indoor air and adds natural humidity.
