When to Plant Boxwood in Kentucky

Growing Boxwood in Kentucky: Complete Guide

Boxwood (Buxus sempervirens) 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 Kentucky falls between March 22, 2027 (Zone 7b) and April 6, 2027 (Zone 6a); early fall works too, once summer heat breaks.

Because Kentucky stretches across 4 USDA hardiness zones (6a, 6b, 7a, 7b), 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.

Boxwood requires full sun to part shade and moderate; shallow-rooted moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
