Hi Uli and All,

I do not agree with you Uli.
I germinate all my Cyrtanthus seeds that way.
And seeds sunken to the bottom do almost always germinate!
Just be patient.
As long as there is an embryo!
Cyrtanthus carneus f.i. might take two to three months to germinate!
By taht time most of the seeds are on the bottom!

But I would not call it the float and sink method. Seeds sinking do not germinate. It is more float and root. With valuable seed I use tweezers to fish them out of the water and plant them individually when the root appears and leave the non sprouted ones floating. But I always remove sinking seeds as they might spoil the rest. Could you feel an embryo when you gently take a single seed between index and thumb? If not the seed may have been empty.
