When to Plant Parsnip in Illinois

Growing Parsnip in Illinois: Complete Guide

Parsnip (Pastinaca sativa) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Illinois falls between February 13, 2027 (Zone 7a) and March 15, 2027 (Zone 5a), once soil temperatures are consistently warm enough for germination.

Because Illinois stretches across 5 USDA hardiness zones (5a, 5b, 6a, 6b, 7a), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 100 days to maturity, Parsnip fits comfortably within Illinois's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Parsnip requires full sun and regular moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
