To keep your Calathea roseopicta (also known as Calathea Rosie) happy, provide it with bright, indirect light, maintain consistently moist soil (but not soggy), and ensure high humidity. Avoid direct sunlight, which can scorch the leaves.Regularly mist the plant or use a pebble tray to increase humidity, and consider using filtered or distilled water to avoid mineral buildup.
Here's a more detailed breakdown: Light: Calatheas prefer bright, indirect light. They can tolerate some morning or evening sun if it's not intense. Avoid direct sunlight, as it can scorch the leaves. Soil: Use a well-draining potting mix that retains moisture. A peat-based mix or a mix of peat moss, compost, and perlite works well. Water: Keep the soil consistently moist, but not waterlogged. Water when the top inch of soil feels dry. Overwatering can lead to root rot. Humidity: Calatheas thrive in high humidity (50-60%). Misting the plant, using a humidity tray, or placing it in a humid room can help. Temperature: Calatheas prefer temperatures between 65-85°F (18-30°C).They are sensitive to cold drafts and sudden temperature changes. Fertilizer: Fertilize with a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season (spring and summer). Don't fertilize in winter. Pruning: Remove yellow or brown leaves at the base to maintain a tidy appearance.
