When to Plant Cilantro in Ohio

Growing Cilantro in Ohio: Complete Guide

Cilantro (Coriandrum sativum) is a crop that grows best when sown directly in the garden. In Ohio, the right time to direct sow is around Friday, March 13, 2026, once soil temperatures are consistently warm enough for germination.

Because Ohio stretches across 4 USDA hardiness zones (5b, 6a, 6b, 7a), planting windows can shift by as much as two to four 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 45 days to maturity, Cilantro fits comfortably within Ohio's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Cilantro requires partial shade to full sun and regular (keep moist) moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
