Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in fall and winter. Ensure good drainage to prevent root rot.
Avoid waterlogged conditions, especially for potted specimens.
After flowering, deadhead spent blooms to tidy the appearance and prevent seed formation. Remove any dead or damaged foliage in late winter or early spring before new growth begins.
Division can be done during this time as well.
Iris tectorum is easily propagated by division of rhizomes in late summer or early fall after flowering. Plant the divisions with the top of the rhizome just at the soil surface, ensuring good drainage and sunlight.
Repot container-grown plants every 2-3 years, typically in early spring or late summer. Use a well-draining potting mix. Ensure the rhizome is planted just at the soil surface. Increase pot size gradually if needed.
