Answer: Datura seeds should germinate in 21-42 days at 55F-65F degrees. Sow seeds 1/8 inch deep in moistened seed starting mix and cover the seed flats with plastic wrap to help retain moisture and humidity. The seeds should sprout within 6 weeks of sowing. Perhaps you haven't given the seeds enough time to sprout, or perhaps you've sown them too deeply. Try again!
