Dumasia thrives in conditions that mimic its native habitat, where intermittent rainfall is common. This species has adapted to efficiently utilize water, making it relatively drought-tolerant. Watering should be done sparingly, roughly once every three weeks, ensuring the soil dries out between sessions to prevent overwatering. Typically grown outdoors due to its hardy nature, dumasia flourishes when the soil's moisture levels are reminiscent of a light rain shower – not too soggy but never bone dry.
