Water: Water requirements for bearded iris 'Dusky Challenger' vary significantly. Bearded bearded iris 'Dusky Challenger' needs minimal watering when the soil is dry, while Siberian bearded iris 'Dusky Challenger' requires consistently moist soil. Most types can't tolerate standing water, and poorly-drained conditions can lead to root rot.

Fertilize: Bearded iris 'Dusky Challenger' thrives in humus-rich soil. Fertilize in early spring, early fall, and pre-bloom using phosphorus-rich fertilizers (5-10-5 NPK) or balanced options (20-20-20 NPK). Organic fertilizers improve soil health. Water immediately after fertilizing for optimal nutrient absorption.

Pruning: Bearded iris 'Dusky Challenger' features striking, fragrant blooms, requiring pruning after flowering in late spring. Remove spent flower stalks and dead foliage to encourage growth. Early spring cleanup promotes health. These practices enhance air circulation, reduce disease risk, and improve overall aesthetics in the garden.

Propagation: Propagating bearded iris 'Dusky Challenger' by seed can alter flower characteristics; therefore, division is preferred 2-3 months post-blooming. Use a sharp knife to divide, ensuring each segment has a 15 cm rhizome. Trim old parts and leaves to 15 cm, spacing plants 30 cm apart (15 cm for dwarf varieties).
