Origin and Habitat: Cuzco. South-east Peru. Lobivia hertrichianaSN|32675]]SN|32675]] has a very restricted range (extent of occurrence is approximately 20km2) and is only known to occur in two locations: Pisac (Valle de Vilcanota, Urcos, Ocongate, ruinas de Intihuatana), and Huambutio (Urubamba, Ollantaitambo). It is not commonly found. It was once more abundant than at present.
Altitude range: It is present at altitudes between 3,000 and 3,500 m asl.
Habitat and Ecology: This species occurs on steep rocky or sandstone slopes in inter-Andean valleys. One of the locations is near Inca ruins, which are frequently visited by tourists, who disturb the habitat and also collect and use this species as an ornamental. Both of these threats are causing an ongoing decline in the species.

Cultivation and Propagation: Echinopsis hertrichianaSN|32674]]SN|32674]] is a summer grower species that offers no cultivation difficulties.
Water requirements: Water regularly in spring and summer on sunny days (but do not overwater), keep dry in winter
Soils: This pretty lobivia is rather more moisture- and temperature- sensitive than many, so make sure that the potting mixture is very well drained by adding one part of sharp sand or perlite to three parts of a standard material.
Fertilization. Feed with a high potassium fertilizer at the beginning of the growing season, but continuing to use this fertiliser through the season will not suit the majority of succulent plants, as it will promote 'soft' growth that is susceptible to disease
Exposures. Need a bright exposure, full sun or half shade in summer.
Hardiness: It is quite frost resistant if kept dry (hardy to -12° C).
Pests and diseases: Take care Spines can hide mealy bugs.
Propagation: Direct sow after last frost.Stems can be removed for propagation in spring, but let them dry for a few days before potting.
