Fall (mid-September to early November) is the best time to control perennial broadleaf weeds in the lawn with broadleaf herbicides. In order to survive the cold winter, perennial broadleaf weeds are transporting food from their foliage to their roots. In the spring and summer, however, most perennial weeds will be dormant and will not be able to transport food to the roots.
This means that you will need to use a broad-spectrum herbicide, such as 2,4-D or dicamba, to kill the perennial weed. The best way to do this is to apply it in late fall or early winter, when the weed is dormant, and wait for it to die back in early spring or summer. If you wait too long, you may have to reapply a second time, which can be costly and time-consuming.
