Barthea thrives in conditions that mimic its native environment, which is characterized by intermittent dry spells. This species has adapted to be moderately drought-tolerant, requiring hydration less frequently than more water-dependent plants. Its watering schedule should reflect periods of soil drying out, typically necessitating moisture once every 2-3 weeks. As barthea is often cultivated indoors due to its manageable size and decorative appeal, it's important to consider indoor humidity levels; maintaining a consistent ambient moisture can support the plant's health outside of direct watering. For barthea, ensuring well-draining soil will complement its watering routine by preventing root rot during dormancy time.
