Habitat and ecology: Conophytum minutumSN|17466]]SN|17466]] occurs in rocky areas on granite, shale, or quartz gravel flats. Plants of this genus dry up to almost nothing during the resting period and prove very difficult to find at that time. They must be plumped-up and preferably flowering if they are to be seen in the wild.

These plants grow on winter rain and head for summer dormancy. They require little water; otherwise its epidermis breaks (resulting in unsightly scars). Water minimally in summer, (only occasional misting when the plant starts shrivelling), but it will generally grow even in summer if given water. Water regularly in winter after the previous year's leaves have dried up. Requires good drainage. Keep cool and shaded in summer, it needs full sun or light shade. Hardy to -2°C. Ensure a very good ventilation. Avoid to repot frequently. This plant may stay in the same pot for many years.
Propagation: It can be reproduced both by cuttings and seeds. Take the cutting from a grown-up mother plant. Each cutting must contain one or more heads along with a fraction of root.
