The Calathea Roseopicta 'Corona' (also known as the Rose-Painted Calathea 'Corona') is a striking but somewhat "fussy" houseplant. Its care centers on mimicking its native tropical rainforest environment.
Here is a guide to caring for your Calathea Roseopicta 'Corona':
1. Light
Bright, Indirect Light is Ideal: It thrives in bright, filtered light. Think of the light found on the rainforest floor, dappled and never harsh.
Avoid Direct Sun: Direct sunlight will scorch its delicate leaves, causing them to fade or develop brown spots.
Tolerates Medium Light: It can survive in lower light, but the vibrant patterns on its leaves may not be as pronounced.
2. Water
Keep Soil Consistently Moist: The soil should be kept consistently moist, like a wrung-out sponge, but never soggy or waterlogged.
Water When Top Soil is Dry: Water when the top 1-2 inches of soil feel dry to the touch. It's better to slightly underwater than to overwater, which can cause root rot.
Use Filtered or Distilled Water: Calatheas are sensitive to chemicals like fluoride and chlorine found in tap water, which can cause brown tips and edges on the leaves. Use distilled water, rainwater, or tap water that has been left out for 24 hours.
3. Humidity
High Humidity is Essential: This is the most crucial factor for a healthy Calathea. It needs high humidity, ideally above 50-60%.
Signs of Low Humidity: Brown, crispy leaf edges or tips are the most common signs that the air is too dry.
How to Increase Humidity:
Use a humidifier near the plant.
Place the pot on a pebble tray filled with water (make sure the bottom of the pot is not sitting in the water).
Place it in a naturally more humid room like a bright bathroom or kitchen.
Misting offers only a temporary increase in humidity, but can still be done daily for general cleanliness and a small boost.
4. Temperature and Drafts
Warm Temperatures: Calatheas prefer temperatures between 65°F and 75°F (18°C–24°C).
Avoid Cold Drafts: Keep it away from cold windows, doors, air conditioning vents, and heat sources, as sudden temperature fluctuations and cold air will stress the plant and cause the leaves to droop.
5. Soil and Fertilizing
Soil: Use a well-draining, peat-based potting mix. Mixing in perlite or coir can help enhance drainage and aeration.
Fertilizer: Feed with a balanced, diluted liquid houseplant fertilizer once a month during the growing season (spring and summer). Do not fertilize in the fall or winter.
6. Common Issues
Curling Leaves: Usually a sign of underwatering or, more commonly, low humidity.
Yellow Leaves/Drooping: Often a sign of overwatering and potential root rot. Check the soil moisture and ensure good drainage.
Pests: They can be susceptible to spider mites in low-humidity environments. If you spot them (fine webbing or tiny specks), increase humidity and treat with insecticidal soap or neem oil.
