About Shallot
Growing Shallot in South Carolina: Complete Guide
Shallot (Allium cepa var. aggregatum) is a warm-season crop that needs a head start indoors before South Carolina's last frost. Depending on your zone, South Carolina gardeners start seeds indoors between October 25, 2026 (Zone 7b) and December 10, 2026 (Zone 9b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.
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 90 days to maturity, Shallot needs the indoor head start that South Carolina's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.
Shallot requires full sun and regular moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
