Q.I Saved the Seed From My Delphinums

Zone 6-7 | poseysjs added on March 20, 2013 | Answered

I saved the seed from my delphiniums and saved them in the refrigerator and planted some of them. I have them on a heat pad and yet none of them are coming up. I covered them with seed starting soil and covered them with a plastic lid. Do they take a long time to germinate?

Delphiniums germinate from 5 days to 5 weeks. The best soil temperature for germination is 60-68*F. The common failures in germinating delphinium's seed are these. 1) Keeping the soil too wet. 2) Sowing the seed too deeply. Seeds should only be covered with approximately 1/8" of soil. 3) Trying to germinate old seed. Delphinium seed loses its vitality after one year. 4) Freeze the seed in the freezer for two days prior to seeding.
