Originating from regions with moderate climates, callerya has adapted to a watering regimen that reflects its environment's periodic moisture availability. This species thrives on a balance of moisture and well-drained conditions, showing a preference for consistent but not excessive hydration. In cultivation, it requires watering once every three weeks to maintain this equilibrium. As an outdoor plant often subject to the whims of natural precipitation, callerya has evolved to maximize water uptake efficiency during its active growing season, ensuring resilience against variable weather patterns.
