When to plant Peony
Plant bare-root peonies in fall (Iowa State calls September the best month) so roots establish before winter; container plants can go in during spring. Fall is also the time to divide established clumps.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
