Originating from regions with moderate climates, bellevalia has adapted to a consistent moisture level in its environment. It thrives best when the soil is kept evenly moist but not waterlogged, showing a preference for stable hydration rather than extremes of drought or saturation. Watering should be done once every week to maintain this balance. As an outdoor plant, bellevalia benefits greatly from natural rainfall patterns, which complement its growth cycle and reduce the need for supplemental watering during peak growing seasons.
