When to plant garlic in zones 8 to 10: fall, ahead of the first frost
Quick answer
In zones 8 to 10, garlic goes in during fall, usually before the first frost. Georgia Extension says late September through November. Arizona's Yavapai County office says September or October, and San Diego County's master gardeners say October to November. UF/IFAS gives late fall through early winter for Florida. The cold the cloves need comes after planting, from the winter itself. Near Atlanta the typical first frost is November 8, so an October planting has a few weeks to root first.

The reason
Plant first, then let winter do the chilling
Texas A&M AgriLife's garlic sheet says a clove needs temperatures below 40°F for 6 to 8 weeks before it will bulb. After that, bulbs start once days run longer than 13 hours and the soil tops 60°F. Georgia Extension gives the same 6 to 8 weeks and counts them after planting. Arizona's Yavapai County office says 4 to 6 weeks below 40°F after planting.

So in warm zones the cloves go in ahead of the cold weeks, not after the first frost as in zones 3 to 5. Georgia's page says an October planting should be well rooted, with tops above the soil, by November. It also says spring planting leaves too short a season for good yields.

Use your extension service's window: late September through November in Georgia, September or October in Yavapai County, Arizona, and October to November in San Diego County.

Plant early in the window
Give the roots time before the cold weeks. Georgia wants an October planting well rooted by November.

Choose softneck seed garlic
Georgia Extension says softneck garlic is well adapted to the South. UF/IFAS names Artichoke and Creole for Florida.

Count the cloves and set the depth
Use the garlic calculator for the count. Georgia plants cloves 1 to 3 inches deep and 6 inches apart; near the San Diego coast they go under about 1/2 inch of soil.

Other warm states
Florida, Texas and the frost-free coast
UF/IFAS gives late fall through early winter for Florida and names no month. Texas A&M AgriLife's crop sheet gives no month either. It times planting by soil temperature: below 85°F at 2 inches deep.

In the warmest spots a frost date can be missing altogether. The San Diego Lindbergh Field station, zone 11a, has no typical frost date. None of these pages says whether a winter like that gives 6 to 8 weeks below 40°F Our pre-chilling guide looks at that question.

Tips and tricks
- Order seed garlic in late summer. Then it's on hand the week your window opens, instead of arriving halfway through.
- Aim for the first half of the window. Georgia wants October plantings rooted by November. Planting early gives the roots that head start before the cold.
- Get the bed ready ahead. Clear and loosen it the week before, so planting day is one short job.
- Write down when the shoots show. Next fall you'll know whether you planted early or late for your own yard.
- Go by your county if it differs. A state window covers a lot of ground. If your county extension office gives its own months, use those.
Common questions
Questions
When should I plant garlic in zone 8?
Georgia Extension says late September through November, and Arizona's Yavapai County office says September or October. Near Atlanta, zone 8a, the typical first frost is November 8, so an October planting comes well before it.

When should I plant garlic in zone 9?
Georgia's late September through November window covers zone 9a towns like Tifton. UF/IFAS says late fall through early winter for Florida, and San Diego County's master gardeners say October to November.

Can you grow garlic in zone 10?
San Diego County's master gardeners list October to November planting for both coastal and inland areas; inland El Cajon is zone 10a. Texas A&M AgriLife says cloves need 6 to 8 weeks below 40°F to bulb, so in the mildest spots the cold can run short. The pre-chilling guide covers that.

Should I plant garlic before or after the first frost in the South?
Mostly before. At the stations we checked, the published windows open weeks ahead of the typical first frost and close no more than about three weeks after it.

Which garlic grows best in warm zones?
Georgia Extension says softneck garlic is well adapted to the South, and UF/IFAS names Artichoke and Creole for Florida. Georgia says hardneck types may grow there but generally prefer cold winters.
