I just plant seeds directly in pure coconut coir with typically good results if the seeds are fresh. Dry seed can be harder to germinate, typically taking longer and with lower germ rates, but I treat them the same.
I typically start them in communal pots, maybe 20-50 seeds, and when they germinate I separate them out and up pot them individually.

Many thank about your opinion, exactly as you say, I am using dry seed with some months store.
We germinated them with pure coconut but germination rate is very low and we spent more month to have resulted. Fresh seeds had a higher rate a little but it is still a low rate.
After, we changed another method: sterilize as said at first threat, then cut seeds and sow them in agar medium. And after a short time, a big amount seed was covered by white fungi, I think it is fungi. Some seeds sample we tried with a higher concentration and longer time to soak, those seeds did not contract fungi but they also germinated.
I am looking for another method of killing fungus and also bacteria but must ensure good germination rate.
Can you share for me some opinions?
