Cultivation

Grow under glass in cactus compost in full light. Water freely in summer, giving a low-nitrogen feed three or four times. Water less in autumn and keep dry in winter. Hardier than most agaves, and may survive outdoors in a warm position in very well-drained, slightly acid soil in full sun. See hardy cacti and succulent cultivation for further advice
