Against the frost risk in Manhattan
Why these dates
Establish from a division rather than seed - seed-grown mint is variable and often poorly flavoured. Cut back hard midsummer for fresh growth.
Dies back to the root in winter and returns reliably from -25C. Frost is irrelevant to an established plant.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Mint are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Manhattan.
