For proper weed control, identify the type of weeds before selecting one or a combination of herbicides. For example, 2,4-D and dicamba are good herbicides for controlling dandelion and broadleaf weeds in lawns. Then, check the herbicide label to see if it is safe to use with other plants in your garden. Follow all application instructions carefully to ensure success in controlling the weeds.
