How to prune dutch iris

Deadhead immediately after blooming; remove foliage once fully yellow. Cut spent flower stems to the base. Allow all foliage to die back naturally before tidying. In borders, mark bulb positions so foliage isn't accidentally disturbed before it matures.

Leave foliage intact until it naturally yellows — usually by early summer — then cut it to the base. Removing green leaves prematurely weakens the bulb and reduces next year's flowering performance.
