Mesembryanthemum can be grown from seed by sowing indoors in late winter or early spring, ensuring a free-draining compost, light exposure for germination, and consistent moisture at 18-20°C.
Here's a step-by-step guide to successfully growing Mesembryanthemum (also known as Livingstone Daisy or Ice Plant) from seed:
-
Timing: Begin sowing seeds indoors in late winter or early spring, typically February or March. This allows the seedlings ample time to develop before transplanting outdoors after the last frost.
-
Seed Starting Mix: Use a free-draining compost specifically designed for seed starting. This type of mix provides the necessary nutrients and allows for proper drainage, preventing issues like damping-off.
-
Sowing the Seeds:
- Fill seed trays or small pots with the compost.
- Do not cover the seeds. Mesembryanthemum seeds require light to germinate successfully. Gently press them onto the surface of the compost.
- Sow seeds thinly to avoid overcrowding.
-
Watering: Keep the compost consistently moist, but not waterlogged. Use a spray bottle to gently mist the surface to avoid disturbing the seeds.
-
Temperature: Maintain a consistent temperature of 18-20°C (64-68°F). A propagator or a warm windowsill can help provide the necessary warmth.
-
Light: Ensure the seeds receive adequate light. A bright location is crucial for germination. If natural light is insufficient, consider using grow lights.
-
Germination: Under optimal conditions, the seeds should germinate within two weeks.
-
Pricking Out: Once the seedlings are large enough to handle (usually after developing a few sets of true leaves), carefully transplant them into individual pots.
-
Hardening Off: Before planting outdoors, gradually acclimatize the seedlings to outdoor conditions over a period of 1-2 weeks. This process, called "hardening off," involves exposing them to increasing amounts of sunlight and cooler temperatures each day.
-
Transplanting: After the last frost, transplant the seedlings into a sunny location with well-drained soil. Mesembryanthemum thrives in full sun.
-
Alternative Propagation: Mesembryanthemum can also be propagated from cuttings.
By following these steps, you can successfully grow beautiful Mesembryanthemum from seed and enjoy their vibrant blooms.
