You know, Beto, to cut the REAL seed out of the "seed" that is left behind after you eat a mango, yes? You have to take that husk off...

Very carefully, cut around the perimeter, until you can separate the two halves with your fingers and some knife help, and inside will be a kind of kidney bean shaped seed....

And I say just plant it, pointed end down...fatter end up, just under the surface of the soil and see what happens....

Yep, it would surely grow, as I've grown even smaller ones than that, and I'm no expert.

I'd recommend using wet cotton locked in a tart container. It has worked wonders for me.
