The genus arrojadoa requires well-draining soil with a sandy or gritty consistency to prevent root rot. These plants thrive in bright, indirect light but can tolerate some direct sunlight. Water needs vary, but they generally prefer a dry climate with infrequent watering, maintaining a 'soak and dry' approach. When planting, ensure the soil is loose, position the plants with enough space for growth, and water sparingly at first to encourage root development. Consider each species' particular needs, as they may have unique requirements for optimum growth.
