When to Plant Sage in Iowa

Growing Sage in Iowa: Complete Guide

Sage (Salvia officinalis) is a warm-season crop that needs a head start indoors before Iowa's last frost. Depending on your zone, Iowa gardeners start seeds indoors between February 23, 2027 (Zone 6a) and March 15, 2027 (Zone 5a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Iowa stretches across 4 USDA hardiness zones (4b, 5a, 5b, 6a), 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 75 days to maturity, Sage needs the indoor head start that Iowa's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Sage requires full sun (6+ hours) and low to moderate moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
