Wild garlic in Atlanta, Georgia is cool season perennial.  Wild garlic is a deep green, grassy weed belonging to the Lily family.  During the fall wild garlic will  emerge from underground bulbs and starts actively growing throughout the winter and early spring before going dormant again.  More often than not, wild garlic in Atlanta, Georgia is confused with wild onion and vice versa.  However, the blades of the plant are what distinguish them from one another and make them identifiable.  The blades of wild garlic are round and hollow, while the blades of wild onions are flat and non-hollow, very similar to the green onions you would buy at the grocery store.  Unfortunately there are no pre emergence herbicides to fight this invasive weed.   This type of weed is only controlled by using post emergence herbicides which are applied to the plant once is has become established.
