Agave macroacantha can sexually reproduce by seeds and propagate vegetatively by aerial bulbils and ground-level basal shoots and rhizomes. It forms compact patches apparently generated by the multiplication of ground-level offshoots.

Seedlings showed low survival rates. Cohorts placed outside nurse plants died in less than 1 yr, while 1-10
