Lemon balm through the year
Against the frost risk in León de los Aldama
Why these dates
Extremely hardy, to about -25C. Dies to the ground and returns reliably.
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. Lemon balm are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for León de los Aldama.
León de los Aldama sits in zone 10a, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 1, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
