Calatheas are admired for their vibrant patterns and dynamic leaf movements and are a favorite among plant enthusiasts.
Native to tropical rainforests, these stunning plants bring a touch of nature’s artistry into any home. However, their beauty comes with specific care needs.
From light and humidity preferences to their unique nyctinasty behavior—where leaves open and close in response to light—Calatheas require attentive but rewarding care.
Whether you’re drawn to their striking foliage or pet-friendly nature, understanding their requirements will help your Calathea thrive and become a cherished part of your indoor garden.
Light Requirements: Calatheas prefer medium to bright indirect light. Direct sunlight can burn their leaves and cause their vibrant colors to fade. They can tolerate low light but thrive best in filtered light conditions like their native rainforest habitat.
Watering Needs: Water your Calathea when the top 25% of the soil is dry. Distilled or rainwater should be used to avoid leaf burn caused by tap water’s chlorine and fluoride. Ensure the pot has good drainage to prevent waterlogging.
Humidity Preferences: Calatheas thrive in high-humidity environments. If the air is too dry, their leaves may develop brown edges. Use a humidifier, mist the leaves regularly, or place the plant on a pebble tray to maintain humidity.
Temperature Range: These tropical plants prefer temperatures between 65-85°F (18-30°C). Avoid exposing them to temperatures below 60°F (15°C), cold drafts, or sudden temperature changes.
Soil Composition: Use a well-draining potting mix with ingredients like compost, pine bark, coco coir, and perlite. This mix helps maintain moisture without waterlogging the roots.
Fertilization Schedule: Fertilize Calatheas every four weeks during the growing season (spring and summer) with a diluted liquid houseplant fertilizer. Avoid fertilizing during the winter when growth slows.
Nyctinasty Behavior: Calatheas exhibit nyctinasty, a movement where their leaves open during the day and close at night, earning them the nickname “Prayer Plants”.
Pest Management: Calatheas can be susceptible to pests like spider mites and mealybugs. Regularly clean the leaves with a damp cloth and use natural pesticides like neem oil if needed.
Non-Toxic to Pets: Calatheas are non-toxic to pets, making them a safe choice for households with cats and dogs.
Common Problems: Leaf curling or browning can indicate underwatering or low humidity, while yellowing leaves may suggest overwatering. Adjust care routines accordingly to keep your Calathea healthy.
