How to use Gibberllic Acid-3 on seeds? Too late to cold-stratify?
I live in NJ (USDA zone 7a/6b), and purchased native wildflower seeds of 45 locally occurring species of wildflowers -- most of which require cold-stratification; however, the seed was collected from plants in a slightly colder region, and therefore accustomed to a slightly longer cold-stratification period.
If I sow the seeds on January 23, will there be enough of a cold/thaw period for at least some of the seed of these 45 species to germinate this upcoming growing season?
Perhaps I missed the window-of-opportunity. I hope that the seed that doesn't germinate will remain viable in the ground until next year, if so..
I ordered some Gibberllic Acid-3. Can someone hear advice me (and everyone else interested) as to how I can properly utilize the acid in assuring that most of the seed does germinate this year?
