Aethusa, a genus of flowering plants, requires light exposure, regular watering, moderate temperature, and well-drained soil. The basic care issues involve pests like aphids and diseases such as leaf spot. It's vulnerable to frost damage and prefers cooler summer climates. Seasonal adjustments include increased water in the hot seasons and protection from chill in winter. Aethusa thrives best under regular, vigilant care to prevent, detect, and address challenges.
