Why is it a problem for your lawn?
An invasive weed that will happily take over wanted plants in your garden
Control
Red Clover can be controlled with cultural practices, including proper lawn mowing and watering. Physical removal (i.e. “weed pulling”) can be effective, although you will run the risk of spreading the seeds to additional areas of your lawn and landscaping. Glyphosate is a common ingredient in over the counter herbicides and can be effective as red clover weed control. Be careful not to allow this herbicide to drift on to surrounding plants as they could be affected as well. If the infestation is hard to kill a professional lawn care company will use a specially selected herbicide to kill this weed as it will move throughout the weed-killing it completely including the root and safeguard surrounding wanted plants.
