Experts and BHG readers answer.
broad leaf weeds
While a well-fertilized lawn can go far in choking out weeds, there are occasions when a herbicide may be necessary to keep out the unwanted plants. Depending on the type of broadleaf weed, a herbicide containing a combination of 2,4-D and MCPP will likely be effective. It may be helpful to first identify the weed to make sure that it is on the product label as an effective control for it.
