The healthier your lawn is and the tighter the surface is the less chance you have of getting a weed infestation. Other options are to apply pre-emergent herbicides like Oxafert and Oxafert Plus to prevent weeds from germinating. Pre-emergent herbicides are best applied at times prior to seasonal germination, usually around March and September. Or you can use selective contact herbicides to control weeds that have already germinated in your lawn.
