You can remove clover by spraying it with an herbicide that contains 2,4-D without damaging the turf. Clover is a persistent perennial and you may need an herbicide that contains 2 or more ingredients. This herbicide can also damage trees, shrubs and other perennials. The best time to spray is on a non-windy day when the temperatures are below 80.
Please read the label and follow all the directions.
