Land cress through the year
Against the frost risk in Korolev
Why these dates
Sow in late summer, about eight weeks after midsummer, for picking from autumn right through winter. Spring sowings bolt before they bulk up.
Genuinely hardy to -12C or below and often the greenest thing in the garden in midwinter.
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. Land cress are timed for direct sowing 8 weeks after it, and this page simply resolves those offsets against the frost date computed for Korolev.
The median frost-free season here is 157 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
