Lemon thyme through the year
Against the frost risk in Daqing
Why these dates
Hardy to about -18C in dry soil. Winter wet is the usual cause of death, not frost.
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 thyme are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Daqing.
Daqing sits in zone 4b, which is colder than this crop is rated for, so it will need winter protection or a container that can be moved under cover. 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.
