When to Plant Catnip in Georgia

Growing Catnip in Georgia: Complete Guide

Catnip (Nepeta cataria) is a warm-season crop that needs a head start indoors before Georgia's last frost. Most Georgia gardeners begin seeds indoors around Friday, January 23, 2026 and move transplants outside around Friday, April 3, 2026, after the risk of frost has passed.

Because Georgia stretches across 5 USDA hardiness zones (7a, 7b, 8a, 8b, 9a), 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 90 days to maturity, Catnip needs the indoor head start that Georgia's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Catnip requires full sun to partial shade and low (less than 1 inch/week) moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
