Against the frost risk in León de los Aldama
Why these dates
Sow onto warm soil from two weeks after the last frost and every two weeks after that. Cut the main stem at about 30cm and it branches into a bushier, more productive plant.
Killed at 0C with no margin at all. Sow late, harvest until the first autumn frost, and expect the plants to collapse overnight when it comes.
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. Leaf amaranth are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for León de los Aldama.
The median frost-free season here is 329 days, against 30 to 45 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
