Water: Watering requirements for iris histrioides 'Major' differ significantly; Bearded iris histrioides 'Major' needs minimal water, only when soil is dry, while Siberian iris histrioides 'Major' requires consistently moist soil. Most iris histrioides 'Major' species dislike standing water and may suffer root rot in poorly-drained conditions.

Fertilize: Iris histrioides 'Major' thrives in humus-rich soil. Fertilize in early spring, early fall, and pre-bloom with phosphorus-rich (5-10-5 NPK) or balanced (20-20-20 NPK) fertilizers. Organic options enhance soil health. Water immediately after fertilizing to aid nutrient absorption for robust growth and blooming.

Pruning: Iris histrioides 'Major' features vibrant blue flowers and thrives with early spring pruning. After blooming, trim flower stems and remove damaged leaves for growth and airflow, which diminishes disease risk. Avoid heavy pruning to prevent stress, ensuring robust flowering and plant health through regular maintenance.

Propagation: Propagate iris histrioides 'Major' by division 2-3 months post-blooming. Use a sharp knife, retaining a 15 cm rhizome per piece, removing old parts, and trimming leaves to 15 cm. Space plants 30 cm apart (15 cm for dwarf varieties). Avoid seeding due to potential color and shape changes.
