Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, especially during dormancy. Ensure good drainage to prevent root rot.

Reduce watering in late summer and autumn as the plant prepares for winter rest.

Remove spent flower stalks immediately after blooming to prevent seed formation and conserve energy. In late autumn or early spring, trim away any dead or damaged foliage. Avoid heavy pruning on established plants.

Divide overcrowded clumps in late summer or early autumn, typically every 3-4 years. Replant divisions promptly, ensuring the rhizome crown is just at or slightly below soil level. This also helps rejuvenate the plant.

Iris variegata generally prefers to be left undisturbed. Repotting is usually only necessary when the plant becomes overcrowded or to divide it.

This is best done in late summer or early autumn after flowering has finished.
