How to Grow

1. Fill a seedling tray or small pot with a fine, clean, well-draining seed-starting mix.
2. Sow at the right depth — 5–8 mm — the seed needs darkness to germinate, so cover it properly.
3. Water gently with a spray bottle so the seeds are not displaced. Keep the medium moist, not waterlogged.
4. Place the tray where it gets the right light for this plant (full sun). Protect young seedlings from harsh afternoon sun.
5. Under suitable conditions, sprouts usually appear in 14–21 days at 12–18°C; cool soil is essential.

Light, water, soil and feeding

• Light: Full sun
• Water: Keep the soil evenly moist, but water must not stand in the pot or bed.
• Soil: Deep, well-drained loam with compost
• Temperature: 10–25C
• Fertiliser: Monthly balanced feed till spikes form
