How to Kill Common Violet Weeds in a Lawn
- 1). Apply herbicide to common violet weeds in the fall. Although the wild violets can detract from your lawn's appearance, herbicide is more effective in autumn when the plants are preparing for winter by transporting food down to their root systems.
- 2). Apply the dicamba selective herbicide on a calm, sunny day with temperatures between 60 and 80 degrees. Spray the area around the violets thoroughly with the herbicide and saturate the entire plant above the soil level.
- 3). Wait two to three weeks for the violet plants to wither and die back. Reapply the herbicide if any plants remain after this period.
