Against the frost risk in Perm
Why these dates
Very slow from seed and best started indoors well ahead of the season, or simply bought as a plant.
Survives -18C. As with oregano, waterlogged winter soil is the real threat.
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. Thyme are timed from 8 weeks before that frost for an indoor start, with planting out 0 weeks after it, and this page simply resolves those offsets against the frost date computed for Perm.
