What is this weather doing to your garden?

“We are seeing early signs of spring, with daffodils blooming and plants running ahead of normal conditions this year,” says state agricultural climatologist Pam Knox. She warns that “the chance of another frost is still very high.” 

While some U.S. regions, such as the Northeast and Midwest, have experienced consistent cold throughout the winter of 2022, the Southeast region, including Georgia, has seen a winter with varied temperatures.

Those unpredictable temperatures, alongside moisture and frost, may have had a direct impact on plant survival, as plants’ ability to thrive or perish is ultimately determined by the weather.

So, what is this winter weather doing to your garden?

Well, it’s been “interesting,” says Pam Knox, director of the University of Georgia Weather Network and agricultural climatologist in UGA's College of Agricultural and Environmental Sciences.

“We had a cold November, a warm December and most of January,” Knox told The Atlanta Journal-Constitution. “But that’s not an issue here in Georgia. Weather always switches around, it’s very typical to see these wide swings in temperature, and plants are adapted to that.”

So is now a good time to plant for spring? Maybe not so fast.

A good rule of thumb is to plant after the last frost and harvest before the first. Frosts happen when air temperatures dip down between 36 and 32 degrees Fahrenheit. Guessing when that last frost might come can be tricky, so it’s best to wait to garden for an additional two weeks after the last frost.

“People have to keep in mind the frost date for their location,” according to Knox.

“This is the time of the year where most gardens are normally dormant. But we are seeing early signs of spring, with daffodils blooming and plants running ahead of normal conditions this year. December was very warm, January too, so the plants are thinking it’s spring and they are ready to bloom.”

But, Knox cautions, another snap of cold weather could still be lurking around the next corner.

“The chance of another frost is still very high, but if it remains warm until the end of February, things will start to bloom again,” she says.

If your green thumb is getting itchy with the warm winter weather, Knox says now is the perfect time of year to clean out the plantings you don’t want.

But hold out just a little longer on fresh plantings, she cautions, “Even if we are ahead of normal, you’ll still want to wait because we could still get a late frost.”

Knox recommends visiting walterreeves.com for more Georgia gardener tips and tricks.

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. In addition to the physical destruction, the hurricane took an emotional toll on Georgia’s farmers. In response, UGA Extension has prioritized mental health support.

Nothing lasts forever: CAES professor finds solutions to break down ‘forever chemicals’ 12/05/24 Carson McAfee
University of Georgia Professor Qingguo “Jack” Huang always wanted to do one thing: solve problems. Growing up in a small city in central China, Huang’s favorite subject in elementary school was math, granting him the opportunity to work on many problems. In high school, his passion transitioned to science, where he learned he could feed those same interests in a way that benefited others. He was finishing high school in the 1980s when Rachel Carson’s Silent Spring made its way to Chinese newspapers, capturing Huang’s attention.

Wheat breeders spend years meticulously crossing varieties to coax the best traits out of each species, carefully propagating plant varieties that are healthier, heartier and better suited for the environments where they are grown. Professional brewmasters are equally painstaking when choosing the components that will give their beers a specific flavor profile.
