How to Kill the Tubers of Violets

Many species of violets are enjoyed for their vivid purple flowers and ease of growth, but violets are not always a welcome addition to the garden. Wild violets in particular are stubborn, quick-spreading weeds. They may look like pretty little wild flowers with their short height and small, attractive blooms, but they can quickly invade your lawn or the cracks in your patio, becoming an irritating weed. Killing off the tubers may take several treatments, so keep spraying until the plants are gone.

Instructions

In the Lawn
- 1
  Spread a granular triclopyr herbicide over your lawn early in the morning before the dew has evaporated using an herbicide, fertilizer or insecticide spreader. Apply the herbicide in the spring of fall on a day when no rain is expected for at least 24 hours.
- 2
  Leave the lawn undisturbed for 24 hours. Do not water or mow it and keep children and pets off of it.

  Apply the herbicide again in 10 days. Continue to apply it every 10 days until the violets are all dead.
