Here are a few of the more common grassy weeds:

Crabgrass is a controllable annual grass weed.  Applying a pre-emergent in the spring will suppress most crabgrass.  Total control is impossible: up to 80% 1st year; 80-90% 2nd year; and 90-95% 3rd year (under normal conditions). Allowing the lawn to dry out ruins the crabgrass barrier. Raking or disturbing the soil ruins the barrier. Mow the lawn at 2 1/2 – 3 1/2 inches. Crabgrass seeds are photosensitive and need light to germinate. Bare areas are almost impossible to keep free of crabgrass, also hot areas, along street, sidewalk and driveways.


Quack grass is an invasive perennial grass weed. This is no selective weed control for Quack grass, therefore making eradication and control difficult. Fertilawn’s approach to controlling Quack grass is to “choke it out”. Implementing a structured lawn care program and maintaining proper cultural practices will develop a thick healthy turf environment, which will ward off unwanted Quack grass.


Yellow nutsedge is a perennials weedy grass with shiny yellow/ green foliage. The stem is triangular and has 3 leaves coming off of it. Usually located in moist or poorly drained areas. Because of the shallow root system, Nutsedge can be easily erradicated by hand but must be completly pulled out early on in its life. FERTILAWN is able to treat for this weed at the price of an application as a specialty chemical is needed.

 Tall Fescue

Tall fescue is a perennial weedy grass that is a clump former. Dark green in color with wide, rough blades. Because Tall Fesuce comes in clumps, manual erradiction can be used. Chemical controls are available but can be costly and harmful to the surrounding turf environment therefor FERTILAWN choosed not to use them.


Bentgrass can be classified as a commonly found weedy grass in residential lawns. The appearance is low growing, flat (mat forming) and is spread by creeping above ground stolons. Generally Bentgrass is the first grass to go dormant and appear dead during periods of hot, droughty weather. Because of the shallow stoloniferous root system, manual eradication using a rake is recommended followed by topdressing and reseeding.
