hot, dry tropical climates around the globe,
So I take it the plant won’t grow in the Midwest?
We are Zone 7 & have 3 “Maylunggay” (Moringa) trees in large pots. We trim 2 of them back to approx. 4’ height, and the biggest one to ~5’ (above the pot)* and bring them indoors B4 the 1st frost. They stay in a cool room (~45 deg. minimum temperature) until there is no danger of frost. (They usually start leafing out around May 1, for us.) Once several days have been 80 deg. F or more, they are off to the races.
*There will also be at least a couple good size roots growing through the bottom of the pot. We trim those off too and the plants recover fine in the spring. You could probably use a 5 gallon bucket with holes in the bottom for a pot, but 10 gallon pots are better - IF you can move them ok! I believe branches can be cut off and rooted - 3x 5 gallon pot / bucket trees may be more manageable than one 10 gallon pot tree. I suspect a tree outgrowing its 5 gallon bucket could be sold with a few branches trimmed back to finance new buckets and soil. I’d make sure the cuttings were off to a good start before selling the parent. :-)

(I have no idea if cut off roots can be used to start trees - maybe?!)
that excludes a lot of America
I guess it will work for preppers in Tucson
