Cyananthus requires partial shade and well-drained, humus-rich soil, faring best in cool climates. Water the plant to maintain moist soil, avoiding waterlogging. Cyananthus is prone to slug and snail damage, root rot, and foliage diseases, necessitating vigilance and preventive measures. Seasonally, cyananthus benefits from winter mulching for protection and reduced watering during dormancy. In spring, resume regular watering as growth restarts. During summer, look out for excess heat exposure and ensure adequate shading.
