Mint planting calendar for Zone 3
Mint is planted from dormant stock rather than sown, so it runs on a dormancy calendar instead of a sowing one.
Plant dormant stock
March–April
Zone 3's last frost lands around ~May 22, and dormant stock wants to be in the ground before the buds move — while the soil is workable but the plant is still asleep.
At the cold edge
Zone 3 is the cold limit of mint's range (Zones 3–11). Expect winter damage in a hard year: mulch the root zone deeply once the ground freezes, shelter from drying wind, and wrap the trunk or canes on young plants.
