Why these dates

Sow indoors eight weeks before last frost, transplant around the frost date into deep holes. Harvest from autumn right through to spring as needed.

Hardy to -15C and often the only fresh vegetable still standing 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. Leeks 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 Novocheboksarsk.

The median frost-free season here is 153 days, against 100 to 120 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
