Problem with self-seeding violets

The best method is to try to thicken your existing lawn so it chokes out the present and future violets.

Rake up the lawn in two perpendicular directions to open up the soil surface. Cut the grass low to expose the surface.

Overseed the lawn area with a shady mix (mainly fescue and perennial ryegrass) at least two or three times a year.

Rake or brush lightly into soil surface. Fall and spring is a good time to seed. Especially in the summer, mow the lawn no lower than 5 cm (2 in.) high. Also liming, deep watering, aerating, and regular feeding will assist in thickening the lawn.

Weed and feed may not necessarily work.
