Water after transplanting, and then only when the soil becomes dry. Avoid direct contact with the plant when watering, to prevent causing sunburn. At the same time, however, bright light is required in order for this cacti to thrive - provide as much sun as possible. Alkaline soil with a pH between 6.1-7.8 is preferred, and substrate must be well-draining in order to avoid root rot. Although this species is tolerant of light frosts, cacti should be protected when temperatures fall below 50°F. Do not expose to temperatures below 20°F, after which damage or death may occur (USDA hardiness zones 9a to 11b).
F. emoryi can only be propagated from seed, which should be collected from overripe fruits. If sowing outside, plant after the last frost.
