Prayer Plant Care Guide
How to grow and care for Prayer Plant (Calathea spp.)
Calathea spp., commonly known as Prayer Plants, are a popular choice for indoor plant enthusiasts due to their stunning, variegated foliage and unique leaf movements. These tropical plants hail from the rainforests of South America and are known for folding their leaves upward at night, resembling hands in prayer. To thrive indoors, Calathea requires specific care conditions that mimic their natural habitat.

Care
Light
Calatheas thrive in bright, indirect light and should be kept away from direct sunlight, which can scorch their delicate leaves. A north or east-facing window is ideal. While low light is tolerable, providing brighter filtered light helps maintain vibrant foliage and healthy growth.
Watering
Water your Calathea when the top inch of soil feels dry. Ensure the soil remains consistently moist but never waterlogged. Use distilled, filtered, or rainwater to prevent mineral buildup that can cause brown leaf tips. Reduce watering during the winter when growth slows.
Humidity & Temperature
Maintain temperatures between 65°F and 80°F (18°C and 27°C). Calatheas thrive in high humidity (above 50% and ideally 60-70%), making them perfect for bathrooms or areas with a humidifier. Low humidity can lead to browning leaf edges. Misting the leaves, placing the plant near a pebble tray, or using a humidifier can help maintain the required humidity levels.
Soil
Use a well-draining potting mix that retains moisture without becoming soggy. A mix containing peat moss, perlite, and compost is ideal for maintaining proper water retention and aeration. Ensure the pot has drainage holes to prevent water buildup and root rot.
Fertilization
Feed with a balanced, water-soluble fertilizer diluted to half strength once a month during the growing season (spring and summer). Avoid over-fertilization, as it can lead to salt buildup and root damage. Flush the soil periodically to prevent salt accumulation.
Maintenance
Pruning
Prune any yellow, brown, or damaged leaves to improve the plant’s appearance and redirect its energy to new growth. Use clean, sharp scissors to prevent infection.
Cleaning
Wipe the leaves regularly with a damp cloth to remove dust and maintain their ability to absorb light. Clean leaves also help deter pests.
Repotting
Repot every 1-2 years or when the plant outgrows its container. Choose a pot that is 1-2 inches larger in diameter and use fresh potting mix.
Propagation
Propagation of Calathea is best done through division during repotting:
- Select a mature plant – Choose a plant that has multiple clumps of stems and leaves.
- Carefully divide the root ball – Gently separate the clumps, ensuring each division has healthy roots and leaves.
- Plant the divisions – Place each division in a pot with fresh, well-draining soil.
- Provide optimal care – Keep the new plants in a warm, humid environment with indirect light and consistently moist soil.
Common Issues
Yellowing Leaves
Cause: Overwatering, underwatering, or low humidity.
- Solution: Check the soil moisture level. If overwatered, allow the soil to partially dry before watering again. If underwatered, water thoroughly. Increase humidity to prevent further yellowing.
Brown Leaf Tips or Edges
Cause: Low humidity, mineral buildup from tap water, or inconsistent watering.
- Solution: Use distilled or filtered water to avoid mineral buildup. Increase humidity by misting or placing the plant near a humidifier. Maintain consistent watering practices.
Drooping Leaves
Cause: Thirsty plant, overwatering, or temperature stress.
- Solution: If the soil is dry, water the plant thoroughly. If overwatered, allow the soil to dry out partially before the next watering. Ensure the plant is kept away from cold drafts or sudden temperature changes.
Pests (Spider Mites, Aphids, Mealybugs)
Cause: Dry conditions, poor airflow, or dusty leaves.
- Solution: Wipe the leaves with a mixture of water and mild soap. Apply neem oil or insecticidal soap weekly if pests persist. Improve humidity and clean leaves regularly to prevent infestations.
Root Rot
Cause: Overwatering and poor drainage.
- Solution: Remove the plant from its pot and inspect the roots. Trim any mushy or blackened roots and repot in fresh, well-draining soil. Reduce watering and ensure the new pot has drainage holes.
Additional Tips
- Water Sensitivity: Calatheas are sensitive to minerals and chemicals in tap water, which can cause browning. Using filtered or distilled water is highly recommended.
- Environmental Sensitivity: Avoid exposing the plant to cold drafts or sudden temperature fluctuations, as these can cause leaf curling or browning.
By understanding the specific needs of Calathea spp., you can enjoy their stunning foliage and unique movements while ensuring they thrive in your home.
