When to Plant Garlic in South Carolina

Growing Garlic in South Carolina: Complete Guide

Garlic (Allium sativum) is fall-planted — it goes in the ground a few weeks before the first fall frost and overwinters for harvest the following summer. Depending on your zone, South Carolina gardeners plant between October 25, 2026 (Zone 7b) and December 10, 2026 (Zone 9b).

Because South Carolina 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 240 days to maturity, Garlic fits comfortably within South Carolina's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

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