Start seeds indoors

Mar 11 – Mar 25

Wisconsin 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.

UMN Extension says the easiest and most successful way to grow chives is planting rooted clumps in spring after frost danger has passed, and Wisconsin Horticulture likewise puts indoor-started plants out after the danger of frost is past; both agree, so the window opens at the last spring freeze.
