How do I remove Wild Violets from my lawn? They are taking over!
- Oakland, OR
Wild violets can be quite tenacious and difficult to eradicate as they can spread by reseeding and often by stolons and roots. You can also smother larger patches with black plastic topped with a thick layer of mulch for a year, and then reseed the area with grass seeds once the wild violets are gone. You can utilize the mulched area as a showcase for container plantings during that year.
Best control for spotty areas is to dig up the plant by its roots. If these measures don't work, ridding your lawn of violets may require an herbicide. Look for products containing triclopyr (do not use if your lawn contains bermudagrass), such as Ortho Weed-B-Gon Chickweed, Clover & Oxalis killer. Always look at the label to ensure that the herbicide lists wild violets as one of the weeds that it targets. Best time to spray is in autumn as that is when the plant will more easily take in herbicides. You can use a spray for spot treatment; use granular herbicides for broader applications.
The best way of keeping your lawn from becoming infested in the future is to grow a healthy lawn; mow high and mow often; water deeply to encourage deeper and healthier roots; and aerating and dethatching your lawn will also help.
