After the fail with strelizia reginae, another attempt !
My seeds in bag for 15 days have no signs of germination so i decided to try something again,
this time no more cotton:
==> charcoal and pozzolan
2 Seeds prepared, others not:
One with coat removed (no deep cut, just coat removed)
One with coat cutted, not deep at the "end" . (For this one needs to be extra carefull)
After ONE night:
Coat removed : no signs
Coat cutted : Already a sign
So no need to remove all the coat, i hope this time it will be better!
