Why these dates

Start indoors four weeks before the last frost and plant out two weeks after it into soil kept permanently wet. Cut 20cm of tip growth and it regrows within a fortnight.

Damaged at about 5C, long before frost. It needs consistently warm nights and stops dead in a cool spell.

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. Water spinach are timed from 4 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Kazan.

The median frost-free season here is 149 days, against 45 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
