Against the frost risk in Murmansk
Why these dates
Sow two weeks before the last frost and pinch the tips to keep it leafy. Left alone it reaches head height and goes to seed by midsummer.
Tolerates about -5C. Young plants take a spring frost without checking, which is why it can go in earlier than true spinach.
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. Orach are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Murmansk.
The median frost-free season here is 113 days, against 40 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
