I very carefully cut with a pair of sharp scissors the smallest piece possible following the curve around the thinner side of the seed. Each time cutting a little more until I was able to seperate it with my fingers. Then carefully inserted scissors and cut away at the coat. Don't worry about trying to preserve the inner brown coat on the seed, it's not necessary.

I put the heavy side down so that half the seed was below the soil line and put it out in a semi-sunny location. Within 2 days, the seed started to turn green and within 5 the seedling emerged! 2 actually!

All right thanks for the tips. Sounds like they germinate fast.

Clean the husk with a scrubber under running water and then feel with your finger tip along the flat edge. You will find a small split. Carefully insert a flat spoon handle (NOT a knife, you'll do too much damage] and use it to force the sides a apart a little further. You will now be able to pull the husks apart with your fingers.

There is usually one side edge of the mango seed that is soft and can be cut open. I usually cut that side and just pry it open. Be careful, don't lose a finger. =)
