Start seeds indoors
Jan 24 – Feb 7Wisconsin Horticulture starts chive seed indoors before the last frost date for planting out after frost danger, but says only 'a few weeks'; USU Extension fixes the lead time at 6 to 8 weeks of growth before garden planting, so sowing runs 8 to 6 weeks before the last spring 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.
