To plant living stone plants (Lithops), sow the seeds directly onto a finely sifted, fast-draining potting mix in spring or autumn. Lightly press the seeds into the soil, but do not cover them, as they need light to germinate.
Here's a more detailed breakdown:
Preparing the Soil and Container
- Potting Mix: Use a well-draining mix specifically formulated for succulents or cacti. A good mix might consist of coarse sand, perlite, and a small amount of potting soil (aim for a mix that is at least 70% inorganic material).
- Container: Choose a shallow pot with drainage holes. Living stones have small root systems, so a deep pot is unnecessary and can lead to moisture retention issues.
Sowing the Seeds
- Sowing Time: Spring or autumn are the best times to sow living stone seeds.
- Sowing Technique:
- Moisten the potting mix thoroughly before sowing.
- Sprinkle the seeds evenly over the surface of the soil.
- Gently press the seeds into the soil. Do not cover them, as light is required for germination.
Germination and Early Care
- Light: Living stone seeds require light to germinate. Place the pot in a bright location, but avoid direct sunlight, which can scorch the seedlings.
- Humidity: Maintain high humidity levels during germination. You can cover the pot with a plastic bag or dome to create a humid environment, but be sure to provide adequate ventilation to prevent fungal growth.
- Watering: Keep the soil consistently moist, but not waterlogged, during germination. Misting the surface of the soil is often the best approach.
- Germination Time: Germination can occur in as little as seven days, but may take several months, so be patient.
Post-Germination Care
- Gradual Acclimation: Once the seedlings have germinated, gradually reduce humidity levels and increase exposure to light.
- Watering: Allow the soil to dry out slightly between waterings. Overwatering is a common cause of death for living stone seedlings.
- Repotting: Repot the seedlings into individual pots once they are large enough to handle.
Important Considerations:
- Dormancy: Living stone plants go through a dormancy period, typically in the winter. During dormancy, they require very little water.
- Overwatering: Avoid overwatering at all costs, as this can lead to root rot and death.
- Sunlight: While living stones need bright light, they can be sensitive to direct sunlight, especially during the hottest parts of the day.
By following these steps, you can successfully plant and care for your living stone plants.
