It turns out that the best way to propagate Moringa from scratch is to either get a cutting , or to plant a seed directly into the growing site set aside for the tree.  I have failed quite a few times trying to get a Moringa to grow in a pot past 20 cm in height, first it was the direct sunlight it wasn't liking, then, once that was addressed, it looks like the tap root hit the bottom of the pot and they just started to wither.  Thank you to Edge of Nowhere Farm for the handy tip.
