Start seeds indoors

Transplant outdoors
Apr 11 – Apr 25UMD Extension names sage among herbs started indoors and planted outside after the danger of frost has passed, which coincides with Wisconsin Horticulture's direct-sow date, so the window opens at the last spring freeze.

Direct-sow outdoors
Apr 11 – Apr 25Wisconsin Horticulture gives a point rule — plant sage seed directly in the garden on the average date of last frost — which opens a two-week sowing span beginning at that date.

Variety assumption: Wisconsin Horticulture notes seed-grown sage may not flower the first year; culinary leaf harvest is unaffected.
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.
