Broadleaf weeds, of which there are many common types, are among the most bothersome pest in lawns. The development and maintenance of a dense, healthy lawn is the best control strategy for reducing the amount of broadleaf weed problems developing in home lawns. 
Living in an uncontrolled environment it is impossible to eradicate all weeds; but the best way to minimize weeds in your lawn is through good cultural practices. Mow at 3 inches and never to cut more than 1/3 of the total grass plant, irrigate deeply and infrequently, fertilize according to your turf needs usually between 2-4 pounds of nitrogen per 1000 ft squared per year, and core aeration should be done annually. On the other hand mowing your lawn too short or not often enough, fertilizing too much or not enough, and over- or under-watering will all contribute to heavier germination of broadleaf weeds. 
Broadleaf weeds are generally the easiest to identify of all the weeds. They have leaves that are broad, and are generally produced in pairs or multiples. Broadleaf leaves may be simple (having one leaflet, like dandelion) or compound (having more than one leaflet, like clover). Veins within the leaf give a netted appearance in most cases. Broadleaf weeds can be divided into two categories: cool season and warm season broadleafs. Cool season broadleafs like Dandelions, Clover, Ground Ivy (Creeping Charlie), and Plantain emerge in the lawn and are actively growing in the cooler soil temperatures of the spring and again in the fall. Warm season broadleafs like Black Medic, Spurge, Wood Sorrel, Purslane, and Oxalis emerge in the lawn during the warmer summer months.
The most effective way to treat broadleaf weeds is with a liquid product that can be readily absorbed into the plant through its leaf surface. The most common herbicide choice is a general- purpose post emergent mixture comprised of two or three of the following individual herbicides or active ingredients: 2,4-D; MCPP (mecoprop); and dicamba (Banvel). This means broadleaf weeds need to be treated "post emergently" or after they have become visible in the lawn. Since weeds continue to emerge throughout the growing season as soil temperatures change, a minimum of four weed control treatments need to be applied. Weeds such as Ground Ivy (Creeping Charlie), thistles, and wild violets are difficult to control because they spread by underground rhizomes and stolons. Multiple herbicide applications may be necessary to completely control difficult perennial weeds.
In conclusion, it is impossible to have 100% weed control in your lawn. By combining cultural methods and an application of broadleaf herbicide at least four times per year, however, you should be able to significantly minimize the number of broadleaf weeds in your lawn.
