When to Plant Rosemary in Alabama

Growing Rosemary in Alabama: Complete Guide

Rosemary (Salvia rosmarinus) is a warm-season crop that needs a head start indoors before Alabama's last frost. Depending on your zone, Alabama gardeners start seeds indoors between December 2, 2026 (Zone 9b) and January 25, 2027 (Zone 7b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Alabama stretches across 5 USDA hardiness zones (7b, 8a, 8b, 9a, 9b), 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 120 days to maturity, Rosemary needs the indoor head start that Alabama's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Rosemary requires full sun (6+ hours) and low (drought tolerant) moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
