Keep Jack Frost Out of Your Garden

Getting your garden off to an early start is fun and rewarding. The fun part is helping your plants outmaneuver Mother Nature and grow better and faster with your help than they could on their own.

It's also rewarding to have fresh-from-your-garden vegetables days or even weeks before your neighbors. Planting early helps you avoid many insect and disease problems, too.

There's no doubt about it. An early garden can be highly rewarding. The bad news is that late spring frosts can wipe out young warm-season vegetables before you can say Jack Frost.

The good news is that keeping Jack Frost out of your spring garden isn't hard to do. It just requires some planning ahead of time.

The key to avoiding frost is knowing the average date of the last spring frost for your area. In the press this is usually called the spring average frost date.

The average frost date doesn't predict the exact date on which the last spring frost will occur. It's the average date of the last spring frost based on annual observations over many years.

How do you use the AFD to schedule planting of an early garden?

The actual frost date in any year is usually within two weeks of the AFD. So by delaying planting your garden until two weeks after the AFD, you can be all but certain that when Jack visits, your veggies won't be at home.

To effectively use the AFD to schedule planting your garden, you must know the AFD for YOUR area. The following table shows AFDs for a number of places in Georgia.

If your area isn't in the table, check with your county extension office (or call 1-800-ASK-UGA1) to find out the AFD for your area.

To enjoy the benefits of an early garden, plant early -- but not too early!

UGA Extension supports resilience in Georgia farm communities after Hurricane Helene 12/19/24 Emily Cabrera
Hurricane Helene wrought sweeping devastation across Georgia’s agricultural sector in late September, leaving an indelible mark on both the land and the people who tend it, bringing focus to vulnerabilities in Georgia’s farming industry and the need for more robust safety nets.

Arriving on the Athens campus of the University of Georgia in August 2023, five Romanian scholars experienced the same anticipation, excitement and apprehension as many first-year students.  Chosen as Fulbright Romanian-American Foundation Scholars, each serves on the faculty at one of three Romanian universities, specializing in fields from economics and engineering to plant breeding and biotechnology. The five scholars comprised the first cohort of the Romanian Extension Education Development Program, an ambitious three-year pilot effort to facilitate planning and implementation of extension services in Romania.

A larger-than-life legacy: CAES student’s contagious enthusiasm inspired others 12/17/24 Jordan Powers
When Miriam Edelkind-Vealey applied for a summer role at a University of Georgia pollinator biodiversity lab in 2020, the junior undergrad didn’t quite know what to expect. After being told she got the position, Edelkind-Vealy didn’t hear anything for a few weeks. It was only then that she learned a collaborator on the project, second-year master’s degree student Amy Joy Janvier, had passed away.

CAES researchers look to reduce food waste by extending shelf life 12/16/24 Lillian Sosbee
“Use by,” “Sell by” and “Best by” dates on food packaging can be helpful indicators of how long a consumer can store a food item before eating, but often these dates lead to high quantities of wasted food. About one-fifth of food produced for human consumption is discarded before it can be eaten, equating to 1 billion meals a day and contributing to global food insecurity.
