Sugar snap peas through the year
Against the frost risk in Perm
Why these dates
Sow five weeks before the last frost with support in place from the start. Heat ends the crop, so an early sowing matters more than a large one.
Hardy to about -6C as a plant. Peas germinate in soil at 7C, which is usually weeks before the last frost date.
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. Sugar snap peas are timed for direct sowing 5 weeks before it, and this page simply resolves those offsets against the frost date computed for Perm.
The median frost-free season here is 135 days, against 60 to 75 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
