The pholisma genus primarily consists of hardy, desert-adapted plants. The basic care for pholisma involves exposure to full sun, infrequent watering mimicking its natural arid habitat, and a temperature range reflecting desert conditions. Pholisma prefers well-draining sandy or gravelly soil. Common challenges for this genus include overwatering, susceptibility to root rot, and intolerance to cold temperatures. When it comes to seasonal considerations, they require less water in winter, and extra attention during summer for potential pest invasion, such as aphids and spider mites.
