When to Plant Cilantro in Wyoming

Growing Cilantro in Wyoming: Complete Guide

Cilantro (Coriandrum sativum) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Wyoming falls between March 28, 2027 (Zone 5b) and April 17, 2027 (Zone 4a), once soil temperatures are consistently warm enough for germination.

Because Wyoming stretches across 4 USDA hardiness zones (4a, 4b, 5a, 5b), 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 Wyoming'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. Mountain-state gardens contend with short seasons and intense UV at elevation — cold nights can persist well into June at higher altitudes.
