Direct-sow outdoors

Feb 24 – Mar 10

Utah State University Extension lists endive seed in its semi-hardy Group B, planted "about 2 weeks before average last spring frost", so the point rule opens a 14-day span from last spring frost minus 14 to the frost date itself; Minnesota's earlier "as soon as the soil is workable" is superseded by the later, more frost-conservative USU interval. Anchored to the median last spring freeze (Mar 10).

Fall planting

Aug 19 – Sep 2

University of Minnesota Extension's direct-seeding guidance for lettuce, endive and radicchio says to "sow seed about three months before the average first fall frost date", giving a 14-day span from first fall frost minus 90 to minus 76 days. Anchored to the median first fall freeze (Nov 17). University of Minnesota Extension · University of Arkansas System Division of Agriculture, Cooperative Extension Service

Variety assumption: Endive and escarole are the curly-leaved and broad-leaved forms of one species (Cichorium endivia) and are treated as a single crop by Arkansas Extension; offsets assume the 85–98 day full-head types in its cultivar table.

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.
