Originating from arid regions, holarrhena has adapted to survive with minimal moisture, exhibiting remarkable drought tolerance. It thrives with infrequent watering, ideally once every 2-3 weeks, maintaining a balance between dryness and hydration. Given its preference for drier conditions, overwatering can be detrimental to holarrhena's health. As a plant more commonly grown outdoors, holarrhena benefits significantly from the natural rain patterns in its native climate zone, which align well with its low water requirements.
