Fall planting
Sep 27 – Oct 11Cornell Garden-Based Learning caps successive arugula sowings at "about a month before your average first frost date", so the fall sowing window is the 14 days ending at that cutoff (first fall frost minus 44 to minus 30 days); Wisconsin Horticulture agrees arugula tolerates frost but gives no numeric offset. Anchored to the median first fall freeze (Nov 10). Cornell University Garden-Based Learning (Cornell Cooperative Extension)
Start seeds indoors
Not calculatedThe cited extension guides do not time an indoor seed-starting window for this crop.
Transplant outdoors
Not calculatedThe cited extension guides do not time an outdoor transplanting window for this crop.
Direct-sow outdoors
Not calculatedCornell times spring arugula only by soil condition — "Plant as soon as soil can be worked in spring." — which is not an offset from a freeze date, so no spring window is computed here. The window above is the last succession sowing before the first fall freeze.
Variety assumption: No spring window is published: every extension page fetched gives only soil-workability language ("as soon as soil can be worked") or the unquantified "several weeks before the last frost", neither of which yields an honest numeric offset, so only the frost-anchored fall cutoff is encoded.
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.
