UNH: set out after the last frost. Purdue's semi-hardy class allows 2–4 weeks before; the later UNH rule is used (celery is easily vernalized by cold spells). Anchored to the median last spring freeze (Apr 6). University of New Hampshire Extension · Purdue University Extension

Variety assumption: A long, steady season (about 100–120 days from transplant; Penn State lists 120).

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.
