When to plant Catmint
Catmint is a sterile hybrid perennial set out as a plant and propagated by division. Plant in spring once the soil is workable; NC State notes it rapidly forms a clump and blooms from spring into summer, and that shearing after flowering encourages repeat bloom.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
