Generally speaking late flowering plants are divided in spring so they have time tosettle and grow before expending loads of energy on flowering. Hostas and ornamental grasses also seem to do best if divided in spring. Early flowering perennials are divided in autumn to give them time to re-establish themselves.
Bearded irises can be split immediately after flowering in late spring.
