It occurs on rocky slopes and flats with clay ground.
About 20% of this species' habitat has been lost to agriculture, predominantly vineyards and orchards in the Koue Bokkeveld, but land cover data show no significant ongoing loss of habitat. Collections from fallow crop fields near Vredendal indicate that it is able to recolonise disturbed areas.

Gladiolus ceresianus is a widespread species occurring in small, scattered subpopulations. The population is not suspected to be declining.
