About Shallot
Growing Shallot in New Hampshire: Complete Guide
Shallot (Allium cepa var. aggregatum) is a warm-season crop that needs a head start indoors before New Hampshire's last frost. Depending on your zone, New Hampshire gardeners start seeds indoors between September 10, 2026 (Zone 4a) and October 10, 2026 (Zone 6b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.
Because New Hampshire stretches across 6 USDA hardiness zones (4a, 4b, 5a, 5b, 6a, 6b), 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 New Hampshire'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. In the Northeast, cool summers and moderate humidity can slow warm-season crops, so choose a sheltered, south-facing spot to maximise heat.
