Water: Dwarf lake iris thrives in moist environments, preferring regular hydration while avoiding waterlogging. Weekly watering is recommended to mimic its natural habitat. It benefits from well-draining soil, ensuring balanced moisture levels for optimal growth during its growing season.

Fertilize: For optimal growth, dwarf lake iris needs a balanced fertilizer high in phosphorus during its active spring growth, every 4-6 weeks. Avoid over-fertilization to prevent root damage and cease fertilization in fall and winter. Use slow-release pellets and water thoroughly after application to distribute nutrients.

Pruning: Dwarf lake iris thrives with vibrant blue flowers and compact growth. Prune after blooming in early to late spring, removing spent flowers and dead foliage to promote health and prevent energy loss. Clean tools help mitigate disease, and regular pruning improves airflow and plant vigor.

Propagation: Propagate dwarf lake iris by carefully lifting and separating its tubers after the foliage dies back. Ensure each division has a growth point and replant promptly at the same depth to promote successful rooting and development.
