Sowing instructions:
1. Prepare the Seeds
-
Optional but helpful: Scarify the seeds lightly by rubbing them with fine sandpaper or nicking the seed coat. This helps water penetrate and speeds up germination.
-
Soak the seeds in warm water for 12–24 hours before sowing to soften the outer coat.
2. Soil Mix
Use a well-draining mix, such as:
-
50% cactus soil or potting mix
-
25% coarse sand or perlite
-
25% pumice or fine gravel
🔍 You can also use a succulent-specific mix amended with extra drainage materials.
3. Sowing the Seeds
-
Fill small pots or seed trays with the prepared mix.
-
Place seeds on the surface and cover lightly (1–2 mm) with soil or sand — they need light but not full exposure to germinate.
-
Mist the surface to moisten evenly.
4. Ideal Conditions for Germination
-
Temperature: Warm — 22–28°C (72–82°F) is ideal.
-
Humidity: Moderate; cover pots with plastic wrap or a humidity dome, but vent daily to avoid fungal issues.
-
Light: Bright indirect light or filtered sun. Avoid intense midday sun on young seedlings.
🕰 Germination time: Usually 2 to 4 weeks, though it can take up to 2 months.
