Just very slowly, one by one. I wouldn't plant the whole bunch in a hole, they will become huge tree's. You have plenty seeds so just untangle them very carefull.
The pingan's will die (some of them), mine grew well but if the leaves start hanging it will die and i can't stop it. All pedalais do well here, no casualty's so far.
I would like to know which of those 2 smells the most so i can plant it at the edge of the garden. I hope they don't smell like chempedak.
