Question:

How do I control white clover in my lawn?

Answer:

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.
