• Fine, well-draining seed-starting mix
• Plastic wrap or humidity dome (until germination)
• Spray bottle for misting

Sowing the Seeds

• Mist gently; keep the surface evenly moist.

Provide the Right Conditions

• Light: Bright, indirect light until germination.
• Temperature: 70–75°F (21–24°C).
• Humidity: A cover helps; ventilate once sprouts appear.

Germination

• Early emergence can begin around day 6; allow 10–14 days.
• Move to bright light as soon as seedlings emerge.

Transplanting

• Transplant after the last frost into shade or partial shade.
• Harden off before planting out.
• Space 10–12 inches apart.

Care Tips

• Sun: Partial to full shade; some morning sun is tolerated.
• Water: Keep soil evenly moist; do not let plants wilt.
• Fertilizer: Feed lightly during the growing season for the best leaf color.
• Pinch stem tips to encourage bushier plants; remove flower spikes to keep foliage full.
