The fennels genus, commonly referred to as fennel, appreciates full sun, and well-draining, fertile soil, typical of its Mediterranean origin. The Basic Care Needs include regular watering, with adjustments during exceptionally hot or rainy periods, and a preference for cooler temperatures. Common Challenges include pests like aphids and diseases such as powdery mildew. The plant is sensitive to harsh frosts, requiring extra protection in winter. Seasonal Considerations involve reduced watering in autumn and winter and protection against summer heat. Despite these, fennels is a resilient genus with a relatively relaxed care regime.
