Against the frost risk in Yaroslavl
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.

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 Yaroslavl.
