SCIENTIFIC NAME: Dahlia variabil
LIGHT PREFERENCE: Sun.
PLANT HEIGHT: 40-60".
PLANT SPACING: 9-12".
HARDINESS ZONES: Annual.
SOWING:
- Sow 4-5 weeks before last frost. Cover seed with growing medium and keep soil surface moist until emergence. When seedlings have true leaves, transplant into larger cell packs. To maintain healthy seedlings, do not allow plants to become root bound and do not disturb roots. Direct seed
- After last frost when soil is 65-70°F (18-21°C), sow thinly, 2 seeds/ft, 1/4" deep. Cover lightly but firmly. Keep surface moist until emergence. Thin to 9-12" after first true leaves appear.
Once you - decide to grow dahlias from seed, you will want to start your dahlia seeds indoors.
Start your seeds indoors 6-8 weeks prior to your last frost date so they have enough time to get growing so that they can flower in the summer months. It takes about 100-120 days for the seeds to produce flowers. To get your dahlia seeds germinated, take two wet paper towels, and place the dahlia seeds flat on one. Cover the dahlia seeds with the other paper towel. Place the paper towels and seeds inside a zip lock bag. Lay the zip lock bag flat on the top of your refrigerator. Leave the seeds for 3-5 days. Then start checking the bag daily for signs of germination. Once the seeds have germinated, carefully plant the seedlings in a seed tray under grow lights
