When to Plant Chamomile in Montana

Growing Chamomile in Montana: Complete Guide

Chamomile (Matricaria chamomilla) is a warm-season crop that needs a head start indoors before Montana's last frost. Depending on your zone, Montana gardeners start seeds indoors between March 4, 2027 (Zone 6b) and April 8, 2027 (Zone 3b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Montana stretches across 7 USDA hardiness zones (3b, 4a, 4b, 5a, 5b, 6a, 6b), 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 60 days to maturity, Chamomile needs the indoor head start that Montana's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Chamomile requires full sun 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.
