🌱 Seeding Steps for Dahlia pinnata 'Pompon Double Mix'

1. Timing

• Indoors: Start seeds indoors 8–10 weeks before the last frost in your area.

• Outdoors (optional): If your growing season is long (USDA zone 8+), you can direct sow after the danger of frost has passed.

2. Supplies Needed

• Seed starting trays or small pots

• Sterile seed-starting mix (well-draining)

• Dahlia pinnata seeds

• Clear plastic cover or humidity dome (optional but helpful)

• Spray bottle or watering can with fine nozzle

• Grow light or bright windowsill

3. Sowing Instructions

1. Fill containers with moist seed-starting mix.

2. Sow seeds on the surface of the mix — Dahlias need light to germinate, so don’t cover the seeds heavily. Just press them gently into the soil or sprinkle a very thin layer of vermiculite over them.

3. Mist lightly to settle the seeds in place.

4. Germination Conditions

• Temperature: 20–22°C (68–72°F)

• Light: Keep in bright indirect light or under a grow light.

• Moisture: Keep the medium evenly moist but not soggy.

• Germination time: 7–14 days

5. After Germination

• Once seedlings have 2–3 true leaves, transplant them to larger pots.

• Start feeding weekly with a diluted balanced fertilizer (e.g., 10-10-10).

• Ensure strong light to avoid leggy growth.

6. Hardening Off

• 1–2 weeks before transplanting outdoors, harden off seedlings by gradually exposing them to outdoor conditions.

7. Transplanting Outdoors

• Transplant after all danger of frost has passed.

• Choose a sunny location with well-drained, fertile soil.

• Spacing: Plant 12–18 inches apart.

• Water well after transplanting and mulch to retain moisture.

🌼 Bloom Time

• You’ll start seeing flowers in 60–90 days from sowing.

• Deadhead regularly to encourage continuous blooming.
