Siltbush thrives in arid environments, showcasing a remarkable drought tolerance that is reflective of its native harsh, dry habitats. This resilience translates to infrequent watering needs, ideally once every 2-3 weeks to maintain a balance without over-saturating the soil. As siltbush is predominantly an outdoor plant adapted to full sun exposure, it has evolved extensive root systems capable of maximizing water uptake and retention during scarce rainfall periods. In cultivation, ensuring proper drainage is crucial as siltbush's roots are prone to rot if left in standing water.
