Plant Garlic in Zone 9b
Seed-starting, transplant & harvest dates for USDA Zone 9b
Plant cloves in fall, from about the first frost through the following month, so they root before the ground freezes.
Zone 9b averages 298 frost-free days, running from a last spring frost around February 15 to a first fall frost around December 10. Garlic needs roughly 240 days from planting out to first harvest, so it uses about 81 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 9b last frost has passed and the soil has warmed.
Planting garlic for a fall harvest in Zone 9b
Yes. Plant garlic between December 10 and January 7 in Zone 9b, from around the average first frost through the following 4 weeks, so it roots before the ground freezes.
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.
Fall dates are counted backward from the Zone 9b average first frost, not forward from a sowing date. See the fall planting calendar by zone for the full method.
