Is there a safe/nontoxic substance that will kill wild violets in the lawn?Nothing but digging them out by hand seems to work. Does the soil need something to deter them?

Wild violets are really difficult to control because they grow from underground bulbs which store lots of energy for regrowth if the tops of the plants are mowed down. The only way to remove these pesty weeds is to dig them out, roots and all. There's nothing on the organic list that will control these plants. You can try painting the tops of the plants with Round Up but this will kill only the tops, not the bulbs so repeat applications will be necessary. Of course if you get Round Up on your turf, it will kill the turf as well. Wish there were an easier solution, but digging them up, bulbs and all, is the only organic way to eliminate wild violets. Violets prefer acidic soils. When the soil pH is low, the soil is usually calcium deficient. Lime will help adjust the pH and will supply calcium but how much to apply will really depend upon a current soil test. So be sure to test before you apply lime. Good luck with your lawn.
