Xerosicyos thrives in environments that mimic its native arid habitat, requiring minimal water to sustain its growth. Adapted for drought tolerance, xerosicyos prefers a dry climate and can store water efficiently within its structure. Watering should be sparse, aligning with once every two weeks to maintain the right moisture balance without over-saturating the soil. As an indoor plant, xerosicyos benefits from well-draining soil that prevents root rot, typically caused by excessive watering or poor drainage.
