Fall planting
Sep 19 – Oct 19Alabama Extension states an explicit frost-anchored range — plant hairy vetch 15 to 45 days before the killing frost — which encodes directly as 45 to 15 days ahead of the first fall freeze; UMass Extension's general cover-crop rule of about 30 days before the first expected frost falls inside that range, so the wider Alabama interval is used and no conflict needed resolving. Anchored to the median first fall freeze (Nov 3). Alabama Cooperative Extension System · UMass Amherst Center for Agriculture, Food, and the Environment

Variety assumption: Assumes seeding for overwintering and spring nitrogen, commonly drilled or broadcast in a mix with winter rye.
