How do I control white clover in my lawn?
White clover (Trifolium repens) is a creeping perennial. It is a common plant in many Iowa lawns because it is a prolific seed producer and adapts well to mowing and other lawn care practices. Its presence is often a sign of low nitrogen fertility.
White clover in lawns can be controlled through proper fertilization and the application of broadleaf herbicides. Late April/early May, mid-September, and late October/early November are excellent times to fertilize Kentucky bluegrass lawns in Iowa. Broadleaf herbicide products that contain 2,4-D, MCPP, dicamba, or triclopyr provide good control of white clover. Fall applications (mid-September to early November) are more effective than late spring or summer applications.
