Planting Guide for Your Rare Dahlia Pompon Seeds 1. Timing: Indoor Starting (Recommended): 4-6 weeks before the last frost: Start seeds indoors to give your Dahlias a head start and ensure earlier blooms. Outdoor Sowing: After the last frost: Sow seeds directly outdoors when the soil has warmed up, usually in spring. 2. Seed Starting: Prepare Seed Trays: Fill seed trays or small pots with seed-starting mix. Sow Seeds: Sow seeds thinly over the soil surface, about 1/4 inch deep. Misting: Mist the seeds gently with water to keep the soil moist but not soggy. Warmth and Light: Place the seed trays in a warm, bright location. Use a heat mat or grow lights if necessary to maintain a temperature of around 70-75°F (21-24°C). Germination: Germination can take 7-14 days. Be patient and keep the soil consistently moist. 3. Transplanting: Hardening Off: Before transplanting seedlings outdoors, harden them off by gradually acclimating them to outdoor conditions. This involves gradually increasing their exposure to sunlight, wind, and cooler temperatures over a week or two. Spacing: Space Dahlia plants according to their mature size, usually about 12-18 inches apart. Planting Depth: Plant seedlings at the same depth they were growing in the seed tray. 4. Location: Sunlight: Dahlias thrive in full sun, needing at least 6-8 hours of direct sunlight per day for optimal growth and flowering. Soil: Well-drained soil is crucial. Amend heavy clay soil with compost or organic matter to improve drainage. pH: Aim for a soil pH between 6.5 and 7.0.
