There are multiple ways to sow Lithops seeds, but this guide shares a method that has been consistently successful.
Best Time to Sow
- Ideal seasons: Autumn (September–October) or Spring (March–April).
- Lithops can be sown anytime if the right conditions are provided.
Soil (Substrate) Preparation
- Use a well-draining, mineral-based mix with 2-3 mm quartz sand, perlite, and garden soil.
- Avoid substrates with peat as they retain too much moisture.
- Sterilize the soil by baking it at 150°C (300°F) for an hour to prevent fungal infections.
Temperature for Germination
- Daytime: 20–25°C (68–77°F)
- Nigh0ttime: 10–15°C (50–59°F)
- High temperatures lead to poor germination.
Using Fungicides
- Apply a copper-based fungicide (e.g., Cuprozin 35-wp) to prevent fungal infections.
Sowing Process
- Moisten the sterilized substrate with distilled water mixed with fungicide.
- Fill 5×5 cm plastic pots with the substrate.
- Spread the tiny seeds evenly over the surface using folded paper.
- Do not cover the seeds—they need light to germinate.
- Place pots in a clear plastic container for humidity control.
- Keep in bright but indirect light or use a 10-15W LED bulb for 16 hours daily.
Germination & Early Care
- First sprouts appear in 3-4 days; full germination can take up to 60 days.
- Do not open the container for the first two weeks to maintain humidity.
- After germination, remove excess water and mist seedlings once or twice daily with distilled water and fungicide.
- By month three, reduce watering to every 2-3 days.
- First year: Keep the soil moist but not soggy, unlike mature Lithops which prefer dry conditions.
Growing Lithops from seed takes 3-4 years to reach maturity, but with patience, you’ll have beautiful "living stones"!
