If you let them dry on a plate or open bowl for 3 to 4 weeks your germination rates will go up. It is best to presoak them till they sink them put them between damp paper towels.
If they don’t germ within a couple of days. Very gingerly put them between some tweezers or needle nose pliers and crack them open slightly, then put them back in the paper towels.
The tap root should come out in 2 to 3 days.
Another trick is to line a match box or some container with 220 grit sandpaper and shake your seeds around inside for a few minutes. This will thin the seed coat making them easier to pop open.
Until the seeds have air dried for least a month you cant really expect high germination rates unless you assist the seeds open.
Good luck.
