When to Plant Sage in Missouri

Growing Sage in Missouri: Complete Guide

Sage (Salvia officinalis) is a warm-season crop that needs a head start indoors before Missouri's last frost. Most Missouri gardeners begin seeds indoors around Friday, February 13, 2026 and move transplants outside around Friday, April 24, 2026, after the risk of frost has passed.

Because Missouri stretches across 6 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a), 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 75 days to maturity, Sage needs the indoor head start that Missouri'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.
