To propagate Iris pallida, the most common method is to divide the rhizomes after flowering, typically around 5-6 weeks post-bloom, by carefully separating healthy outer rhizomes from the older, spent center of the clump and replanting them individually with the top slightly exposed above the soil level; ensure each division has a healthy root system and a fan of leaves.
Key points about propagating Iris pallida:
Best time to divide: Late summer to early fall, after flowering is finished.
Division process: Dig up the entire clump.
Remove old, decaying rhizomes from the center. Carefully separate healthy rhizomes with attached roots and leaves. Plant new divisions with the top of the rhizome slightly exposed.
Planting considerations: Ensure well-drained soil.
Space new divisions appropriately to allow for future growth. Water well after planting.
