When to Plant Hydrangea in Georgia

Growing Hydrangea in Georgia: Complete Guide

Hydrangea (Hydrangea macrophylla) is planted as nursery stock — a container-grown or bare-root plant from a garden center, not seed. Depending on your zone, the ideal spring window in Georgia falls between February 6, 2027 (Zone 9a) and March 27, 2027 (Zone 7a); early fall works too, once summer heat breaks.

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 120 days to maturity, Hydrangea fits comfortably within Georgia's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Hydrangea requires part shade (morning sun, afternoon shade) and high — keep soil consistently moist moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
