Grow Your Own Beautiful Calathea Plants! Instructions: 1. Select a Suitable Pot: Choose a pot with drainage holes at the bottom to prevent waterlogging. Calatheas prefer well-draining soil. 2. Potting Mix: Use a well-draining potting mix suitable for tropical plants. You can also mix peat moss, perlite, and compost for a suitable growing medium. 3. Planting: Plant your Calathea in the pot, ensuring the root ball is covered with soil but not buried too deeply. Gently press the soil around the plant to secure it. 4. Watering: Keep the soil consistently moist but not waterlogged. Water your Calathea when the top inch of soil feels dry to the touch.
