Time to divide perennials?

Is dividing perennials at any time other than spring and summer a real no no?

    You can always give it a try. Depends on what you're thinking of dividing  :)

    What are you thinking of dividing now?

    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.

    Not a good time, hot dry weather ahead. Autumn or Spring much preferred.

    I have some Anemone Wild Swan which after several years of flowering prolifically has not done very well at all do far this year.

    I'd hang fire until the Autumn in that case. You could also try root cuttings.
