🌿 About Shallot
Growing Shallot in Delaware: Complete Guide
Shallot (Allium cepa var. aggregatum) is a warm-season crop that needs a head start indoors before Delaware's last frost. Depending on your zone, Delaware gardeners start seeds indoors between October 15, 2026 (Zone 7a) and November 1, 2026 (Zone 8a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.
Because Delaware stretches across 3 USDA hardiness zones (7a, 7b, 8a), 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.
With 90 days to maturity, Shallot needs the indoor head start that Delaware'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. Mid-Atlantic summers bring heat and humidity — ensure good air circulation and watch for fungal issues like powdery mildew.
