Keep reading to learn more about bittercress, annual bluegrass, and henbit.

Bittercress weeds can survive the cold winter season.

Bittercress, often called hairy bittercress due to its hairy leaves, is a winter annual weed commonly found in Georgia. Winter annual weeds like this start germinating in the fall. The hairy bittercress weed has outstanding winter hardiness, which is why it can survive the cold temperatures of the winter season. If you notice this weed on your lawn, you need to be careful around it because it can spread up to 1,000 seeds.

The key to managing the growth of hairy bittercress is to prevent the seeds from germinating. This means applying pre-emergent herbicides to prevent this weed from getting a foothold in your lawn. This weed can also be controlled through post-emergent treatments, but preventing this weed from growing is always easier than treating an existing infestation.


Annual bluegrass weeds thrive in Georgia.

Also known as Poa annua, the annual bluegrass weed is a common foe of lawns in Georgia. Spotting this weed is easy due to its fine-textured and bright green leaves that mostly appear in the spring. However, annual bluegrass actually starts establishing in your turf in the fall when soil temperatures drop to less than 70 degrees Fahrenheit. This weed will continue to survive in the winter and return in the spring to form seed heads.

Annual bluegrass weeds spread rapidly. Because of this, controlling its growth can be tough. Applying pre-emergent herbicides in the fall before the weed starts to grow is the best way to control this weed. However, you can also rid your lawn of this weed through post-emergent weed control treatments.

Henbit is easily identified by its purplish square stems and red to purple flowers. This invasive weed can grow up to 16 inches tall and is commonly found in lawns in Georgia.

Despite its short life cycle, henbit can produce more than 2,000 seeds that can remain dormant for 25 years.
