Instructions:

1. Select a Suitable Container: Choose a container with drainage holes at the bottom to prevent waterlogging. Calathea seeds require well-draining soil for optimal germination.

2. Potting Mix: Use a well-draining potting mix suitable for tropical plants. A mix of peat moss, perlite, and compost works well to provide the necessary nutrients and aeration for Calathea seeds.

3. Sowing Seeds: Sow your Calathea seeds in the container, following the specific planting depth recommended for Calathea seeds. Typically, small seeds should be lightly pressed into the soil surface, while larger seeds can be covered with a thin layer of soil.

4. Watering: Keep the soil consistently moist but not waterlogged. Water gently to avoid displacing the Calathea seeds. A misting spray or a fine watering can is ideal for this purpose.

5. Humidity: Calathea seeds often require high humidity for successful germination. Cover the container with a plastic lid or a clear plastic bag to create a humid environment. Remove the cover once the seedlings emerge.

6. Light Requirements: Place the container in a location with bright, indirect light. Calathea seeds need light to germinate, but avoid direct sunlight, which can overheat and dry out the soil.

7. Temperature: Maintain a temperature range between 65-75°F (18-24°C) for optimal Calathea seed germination. Avoid exposing the seeds to drafts or sudden temperature changes.

8. Fertilization: Once the Calathea seedlings have developed their first set of true leaves, start fertilizing them with a diluted, balanced, water-soluble fertilizer. Fertilize sparingly to avoid overfeeding the young plants.
