Well-drained sandy or rocky soils in full sun to light shade. The plants are vegetatively distinctive and are composed of groups of 1-3 fleshy, linear leaves borne along a widely creeping rhizome. They are highly adapted to dry conditions and the plant pictured above was growing in sand in the cactus and succulent garden of the Marie Selby Botanic Gardens in Sarasota, Florida. In cultivation, they must be provided with absolutely perfect drainage, warm conditions and very bright light. Many orchidists have reported especially good results growing them in wide, shallow clay pots filled with pieces of broken clay pots or other similar material.
Scale is a particular problem for tetramicras as it is for many other orchids in the cattleya group.
