When to Plant Chives in Wyoming

Growing Chives in Wyoming: Complete Guide

Chives (Allium schoenoprasum) is a warm-season crop that needs a head start indoors before Wyoming's last frost. Depending on your zone, Wyoming gardeners start seeds indoors between February 28, 2027 (Zone 5b) and March 20, 2027 (Zone 4a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

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 60 days to maturity, Chives needs the indoor head start that Wyoming's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Chives requires full sun to partial shade and regular moisture. Mountain-state gardens contend with short seasons and intense UV at elevation — cold nights can persist well into June at higher altitudes.
