Stratifying Seeds
Information on stratifying Smooth Blue Aster seems to vary. I have had success by either sowing outdoors in the fall or cold moist storage in the refrigerator, starting in November.
I would imagine 30 day would be plenty, but we find it easier to stratify all of our seeds at once. However, I should mention that seeds stratified indoors are checked once a month. On occasion, they have sprouted while in cold storage. If this occurs, use a pair of tweezers and gently plant them into your cells. Keeping them moist and out of direct sun for a few days will improve your success rate.
