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 — Surface sowing — the seed is very small; do not cover, it needs light to germinate.
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 7–14 days.

• Water: Water when the top inch of soil dries. In pots, check daily on warm winter days.
