Direct-sow outdoors
Apr 23 – May 7Maryland Extension says to wait until all danger of frost is passed, Alabama Extension says to plant after any danger of frost has passed, and Texas A&M's crop guide lists the optimum time as soil above 65°F with danger of frost over; all three agree on the last-frost date, so the point rule opens the window at the anchor and runs 14 days. Anchored to the median last spring freeze (Apr 23). Alabama Cooperative Extension System · Texas A&M AgriLife Extension
Fall planting
Aug 2 – Aug 12Arkansas Extension gives an explicit frost-anchored fall range — plant about 65 to 75 days prior to the average frost date — which encodes directly as 75 to 65 days before the first fall freeze; it is the only source in this set that states fall timing relative to frost rather than by calendar month. Anchored to the median first fall freeze (Oct 16).

Variety assumption: Assumes a standard 60–70 day bush or semi-vining southern pea; the fall window is Arkansas' allowance for the crop to set and fill pods before the first freeze.
These windows describe typical years (1991–2020 climate normals), not this year's forecast. Freezes happen outside them — especially in frost pockets, valleys, and urban edges. Watch the forecast before committing tender plants.
