Oats through the year
Against the frost risk in Zapopan
Why these dates
Sow very early in spring for grain. Sown in late summer instead, oats make excellent ground cover that winter-kills cleanly and leaves an easy seedbed in spring.
Seedlings take -7C. Oats sown as a cover crop are deliberately killed by frost around -8C, which is the point - the residue mulches the bed without needing removal.
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. Oats are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Zapopan.
