Originating from humid, tropical environments, iryanthera has adapted to periods of high rainfall followed by drier intervals. This species thrives with a consistent moisture level and is moderately drought-tolerant. Watering should be adjusted to once every 2-3 weeks, allowing the soil to dry out slightly between waterings. As an indoor plant, iryanthera benefits greatly from regular misting to emulate its native humidity levels. In terms of growth cycles, iryanthera's watering needs may decrease during its dormancy period in response to lower metabolic activity.
