Q. How do I get rid of violets growing in my lawn?

A. Violets growing in the lawn are difficult perennial weeds to eradicate.  At the present time, there is no effective chemical treatment that can be applied by homeowners. Only professional licensed turf specialists are able to purchase broad-leaved herbicides to control violets. Hand pulling is a tedious but effective option, providing that the entire root system is removed.
