Hi
I've got only very few experience with arisaemas. For the moment the only one I tried from seed was the flavum, which showed no problem at all to germinate and grow on.
For a few weeks I started A.thunbergii seeds on moist sphagnum. Little and encouraging white tips rapidly appeared on the 6 seeds I had got, so I decided it was time to place the emerging seedlings into an appropriate medium, at about 1 cm under the surface ( temperatur never under 4/5°C).
Since that time, nothing new. And it's already been now 4 weeks ago. So what's going on? Were those white tips only the first roots, which would mean it is normal at all if I don't see anything coming above yet? ( nothing coming out the drainage holes either)
I just hope I didn't do anything wrong with those 6 seedlings?
