How to grow Double Cascade Bold Mix Petunia seeds

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Clear plastic wrap or humidity dome
• Spray bottle for misting

Sowing the Seeds

• Surface sow — do not cover; petunia seeds need light to germinate.

Provide the Right Conditions

• Light: Light for germination; bright light for seedlings.
• Temperature: 72-76°F (22-24°C).
• Humidity: A humidity dome keeps the fine seeds evenly moist.

Germination

• Seeds sprout in 7-12 days.
• Remove the cover once sprouted; let the surface dry slightly between waterings.

Transplanting

• When seedlings have several true leaves
• Harden off for 7-10 days before planting out
• Space 10-12 inches apart

Care Tips

• Sun: Full sun for the heaviest bloom.
• Water: Keep evenly moist; avoid waterlogged soil.
• Fertilizer: Feed every 2-3 weeks with a balanced water-soluble fertilizer to sustain bloom.
• Pinch young plants once to encourage bushier growth.
