Echinocactus grusonii var. brevispinus

	Echinocactus grusonii var. brevispinus (subinermis)	CACTUS ART NURSERY Cultivation and Mail Sale of Cacti and Succulents.

A mutant form with very short spines,

Culture: Frost tender but resistant to very dry conditions, Cold hardiness increases with improved drainage, so keep plants as dry as possible in winter. They grow best in well-drained soil and in a position with full sun, which will help to maintain the lustre of the spines and longevity of the flowers. Provide the plant with extremely well-drained soils, as the plants are subject to crown and soft rot if they remain too moist. Besides, it performs wonderfully in containers, Container media should be coarse as well. Young plants are prone to mealy bug and red spider mite. Propagate from cuttings or seed.
