Seed Treatment:
• Soak seeds in lukewarm water for 6–8 hours before sowing.
• For advanced growers: GA3 (Gibberellic Acid) may improve germination. Use only if experienced—improper use can damage seeds.
When to Sow:
Indoors: 4–6 weeks before last frost (late winter to early spring).
Outdoors: Direct sow in spring after danger of frost or in early autumn in mild climates.
Germination Time:
• up to 21 days.
Optimum Temperature to Germinate:
• 18–21°C (64–70°F)
Light Requirements for Germination:
• Light helps—do not cover deeply.
• Use grow lights to maintain 12–16 hours of light per day.
How to Sow:
• Use well-draining seed-starting mix.
• Sow on the surface and lightly press in—do not bury deeply.
• Mist to keep moist but not soggy.
• Cover tray with clear lid or plastic to retain humidity. Vent daily.
Post-Germination Care:
• Remove cover once seedlings emerge.
• Provide strong light (sunny windowsill or grow light).
• Water gently from the base once seedlings are established.
• Transplant when seedlings have 2–3 sets of true leaves.
Growing Tips:
• Plant in full sun (6+ hrs/day).
• Prefers sandy or loamy soil, neutral to slightly alkaline.
• Avoid overwatering—roots dislike soggy conditions.
• Very fast growing; blooms in 6–8 weeks.
• Deadhead spent flowers to encourage continued blooming.
