Plant Garlic in Zone 6a

Seed-starting, transplant & harvest dates for USDA Zone 6a

Harvest (~240d)
N/A

Plant cloves in fall, from about the first frost through the following month, so they root before the ground freezes.

Zone 6a averages 176 frost-free days, running from a last spring frost around April 20 to a first fall frost around October 13. Garlic needs roughly 240 days from planting out to first harvest, so it uses about 136 percent of that window. Garlic is a hardy crop, which is what decides where in the window it belongs.

Garlic resents transplanting and hates cold soil, so direct sow around N/A, after the Zone 6a last frost has passed and the soil has warmed.

Planting garlic for a fall harvest in Zone 6a

Garlic is the definitive fall crop. Plant cloves from around your first frost through the next four weeks: late enough that they root without pushing much top growth, early enough to establish before the ground freezes hard.
