When to plant Short-toothed Mountain Mint
NC State Extension describes short-toothed mountain mint as a vigorous rhizomatous perennial; if spreading is not wanted, the roots can be pruned in spring with a spade. Set out plants or divisions in spring in moist, well-drained soil. The leaves smell strongly of spearmint and can be used for tea.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
