Germination
Johannes-Ulrich Urban (Thu, 26 Jul 2018 02:52:07 PDT)
Hello Hans and All,
Flotation method:
Thank you for this advice. I was not aware that even sunken seeds would still germinate.
Another point: never throw old seed away. I have sown seeds of Canna tuerkheimii, given to me by James Waddick in 2002 (thank you again, Jim) Out of 5 seeds sown 2 have germinated within days, which I find is not too bad for such old seeds.
Bye for today
Uli
