Weed control in Georgia is a never-ending battle. Just because the temperatures are cooler doesn’t mean weeds have gone away for good. Weeds are opportunists and will take advantage of your lawn any way they can. If you don’t apply pre-emergent weed control in late fall and early winter, your lawn could transform from a green carpet to a tangle of annoying weeds. Here are some of the most common ones.
While most commonly associated with the first round of spring weeds, they are known to appear in Georgia’s lawns during the winter season. It’s hard to miss their bright yellow flowers amidst the greenery. Their name comes from the French “dents de lion,” meaning teeth of the lion. While the flowers don’t have teeth, the jagged edges and spikes on their leaves can certainly feel like a bite. Like most broadleaf weeds, dandelions need lots of direct sunlight to thrive and germinate – something Georgia has in spades. They’re also great at dispersing their seeds, using the characteristic white puffs that blow away in the wind. However, by applying a pre-emergent weed control product in late fall and early winter, you can limit the number of dandelions that surprise you in mid or late winter. It’s also not a bad idea to use a post-emergent product to spot treat for any weeds that slip through the defenses. Be sure that the product you choose is selective, however. This means that the chemical will only kill off weeds and won’t harm your turfgrass, shrubs, or flowers.
Interestingly, annual bluegrass is the most common grassy weed in the world. It grows quite fast and tall – up to 15 inches long! Its leaves are a vibrant green, and the blades of grass have short blunt tips. Its stems are slightly flattened and bent at the base. Each plant can produce roughly 100 seeds in as short a time period as eight weeks. And seeds are viable just a few days after pollination, which means the plant can reseed even in lawns mowed with regularity. There’s also a perennial version of this plant, but that grows lower and doesn’t produce as many seeds as its cousin, so it’s not as big of a nuisance. Annual bluegrass also tends to produce more dormant seeds, which makes pre-emergent weed control a must. You’ll be able to knock out weeds lurking in the soil before they ever have a chance to sprout.
This broadleaf weed is a winter annual that has green or purplish square systems. Its leaves are egg-shaped with toothed margins and prominent veins on the underside. It has a robust fibrous root system and can grow up to 16 inches high. Henbit produces flowers that are reddish-purple in color with darker shades on the lower petals. These flowers will stay for most of the winter and into the spring. Another defining feature is hairy stems.
Speedwell begins to sprout when temperatures dip below the 70s. This weed produces branched stems that grow low to the ground, then turn upright to flower. Leaves grow opposite from one another and form clusters on higher-up stems. These leaves are about 1/2 – 3/4″ long and oval in shape with serrated margins. Both the leaves and the stems contain quite a bit of hair. When flowers bloom, they are approximately 1/4 – 1/2″ in diameter with blue petals and dark blue stripes. If it weren’t so destructive in lawns, the flowers would be rather pleasant to look at. But like wild violets, the cute flowers don’t outweigh the cost of putting up with them.
Believe it or not, chickweed is an edible plant and a member of the carnation family! Though most people would prefer to kill it off than eat it, we don’t blame this. This cool-season annual will be germinating before too long and producing large mats of foliage. It can reach heights of 15 inches and has slender hairy stems. The leaves are oval-shaped, and the plant produces flowers that are small with five white petals. Chickweeds grow in clumps from a center point and branch out in all directions, but if they’ve had a chance to really infest the lawn, they may create multiple clusters that are difficult to distinguish as individual plants.
By working with a professional lawn care company, you’ll be able to get a jump on all winter annuals, no matter how stubborn!
