Start seeds indoors

Jan 27 – Feb 10

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.

Variety assumption: Wisconsin Horticulture warns that direct-seeded chives give little or no harvest the first year, so rooted clumps or indoor-started transplants are the practical route.
