Prevent weeds before they become a problem with a pre-emergent. A pre-emergent, as its name suggests, prevents the weed from emerging in the first place—this is useful if you are expecting the same kind of weed to appear annually or to control weeds before they appear so that you can reduce labor spent outside hand-pulling them or using other expensive chemicals. The window for pre-emergent applications is approaching.
