Care notes

CultivationGrow in well-drained, fertile, neutral to slightly acid soil in full sun; sun on the rhizomes will help to encourage flowering. See also bearded iris cultivation
PruningRemove any dying foliage in autumn, old flower stems can be cut down after flowering. Tall cultivars can have their leaf fans trimmed to one third of the total height to reduce wind rock while the plants are establishing
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
