When to Plant Ginger in Colorado

Growing Ginger in Colorado: Complete Guide

Ginger (Zingiber officinale) is a warm-season crop that needs a head start indoors before Colorado's last frost. Depending on your zone, Colorado gardeners start seeds indoors between January 30, 2027 (Zone 7a) and March 6, 2027 (Zone 4a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Colorado stretches across 7 USDA hardiness zones (4a, 4b, 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 270 days to maturity, Ginger needs the indoor head start that Colorado's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Ginger requires partial shade (3-5 hours) and moderate-high (consistent moisture) moisture. Mountain-state gardens contend with short seasons and intense UV at elevation — cold nights can persist well into June at higher altitudes.
