Care notes

CultivationGrow in well-drained, fertile, neutral to slightly acidic soil in full sun. Do not cover the rhizomes with mulch, or allow other plants to shade them, as sun on the rhizomes encourages flowering. Give a high-potash feed in spring and divide every three to four years. See bearded iris cultivation
PruningOld flower stems can be cut down after flowering; remove any dying foliage in autumn
PropagationPropagate by division of rhizomes from midsummer to early autumn, see Dividing irises
Pest resistanceMay be susceptible to slugs, snails and thrips
Disease resistanceMay be susceptible to aphid-borne viruses, bacterial soft rot and grey moulds; see Iris diseases
