Utilizing herbicides are a great way of managing the growth of grassy weeds in turf, however, if grassy weeds is a regular problem that springs up every year for you, this may be an indication of your lawn having been weakened or compromised by some types of environmental condition, the presence of lawn pests, or lawn care practices that are not being conducted properly.

Whether annual or perennial, grassy weeds are tough, aggressive plants that thrive on areas of your lawn that have not be properly maintained or have been under stress. Examples of stress include dried-out lawns, thin patches, sun - areas that have been scorched or even on the opposite end where an area has too much shade are primary spots for grassy weeds, the conditions are prepped for them to be invited in. The best way to combat these unsightly weeds is to learn how they function, what conditions they enjoy being in and then do your best to deprive them of their favorite scenarios where they thrive.


Common Types of Grassy Weeds Which Grow On Lawns

Perennial grassy weeds typically only live on one growing season so they have to work quickly. Since their lifespan is only for a season, they work overtime to produce hundreds or even thousands of seeds which remain dormant until the following spring. Over time, they can completely overrun your yard. Here are some of those common weeds that attack lawns.



This grassy weed derives its name from their leaves, which form a tight circle resembling a crabs- claws.. This annual weed typically appears in weak or bare areas of a lawn. This hard-to-control weed tends to grow both from overwatering or underwatering, as well as from moving the low too short.



Nutsedge is a perennial sedge that forms dense colonies where they grow which can quickly overtake a yard. A variation of nutsedge includes yellow nutsedge. These grass-like leaves, v-shaped in cross-sections.


Annual Bluegrass

An annual weed as their name suggest, annual bluegrass blends well with fescue lawns, but can also stand out in other turf types. They usually emerge where soils are poorly drained or when overwatering has occurred.


There are also many others include oxalis, quackgrass, and barnyardgrass.


Cultural Lawncare Practices To Assist With Grassy Weed Control

As we mentioned earlier, herbicides alone will not be enough to keep grassy weeds off of you lawn. You must combine herbicide usage with an improved lawn maintenance plan by implementing the following helpful tips.


  • *Make sure to more your grass as high as you practically can during the summer months for the particular grass species you are growing on your lawn. Mow grasses such as bluegrass, buffalograss, tall fescue, fine fescue and ryegrass between 2.5 to 3 inches during the summer. A lawn where you mow high helps fight weed seed germination. Also, the higher mowing height produces a healthier grass plant. Crabgrass and other annual grassy weeds are much more common and aggressive in lawns that are mowed at a lower level (less than 2 inches).

  • *Establish a lawn mowing routine that is regular enough so that no more than one-third of the grass blade is removed in a single mowing. Letting grass grow tall and then cutting it back to a low height reduces turf density, allowing grassy weed seeds to germinate and grow more easily. It is especially important to mow a lawn more frequently in the spring, when the grass is growing faster. A lawn may require mowing every three to five days during the spring and early summer.

  • *Apply proper watering to your lawn. Light, frequent irrigation encourages weed seed germination, even if a pre-emergent herbicide has been applied.

  • *Fertilize according to the needs of your lawn species. Have a rich well-fertilized lawn can fight off grassy weeds from taking over. You should also aerate at least one time a year to reduce soil compaction.

Pre-Emergent Herbicides For Grassy Weed Control


Pre-emergent herbicides are made to get rid of annual grassy weeds, such as crabgrass, foxtails, goosegrass, and annual bluegrass, while they germinate in the soil. Annual grassy weeds normally reach their full life cycle in one growing season and return year after year from seed.


When using pre-emergents, it is important to understand which weeds these herbicides can and cannot control. Most pre-emergent herbicides will consistently control crabgrass, foxtails, and annual bluegrass and some may or may not control sandbur.


Nutsedge, a stubborn grassy weed, and Dallisgrass are perennial weeds and cannot be adequately controlled by pre-emergent herbicides. These weeds have the ability to reproduce by underground nutlets and rhizomes. Typically, perennial weeds are more difficult to control than annual weeds because of their ability to make a return from underground plant parts.


To ensure successful pre-emergent weed control timing of the application is critical because most pre-emergent herbicides will not control grassy weeds which have already grown or emerged at the time of herbicide application. The ideal time to apply a pre-emergent herbicide is two weeks before weed seed germination.  A grassy weed like crabgrass can germinate from late spring to early summer, depending on the location.


A general rule is to apply pre-emergent herbicides by mid to late March for control of crabgrass and foxtails. Annual bluegrass germinates in late September, if their is sufficient moisture. Knowing this, make pre-emergent herbicide applications by September 15 for the control of annual bluegrass.


Make sure when using pre-emergent herbicides to perform uniform coverage across the lawn to establish a chemical barrier on the soil surface. Make sure not to have any skips or streaks, which may allow weeds to appear in the lawn later in the year.


Pre-emergent herbicides break down during the summer months, most quickly when summers are muggy and rainfall is occurring more than usually. Thus, weather or watering which creates a rapid breakdown can lead to a lawn infested with a late germinating annual grass. As a result, grassy weeds can become a problem in lawns which are not mowed, fertilized or irrigated properly, even when a pre-emergent herbicide is used.


With normal weather patterns, most pre-emergent herbicides deliver good to excellent control of crabgrass, foxtail and barnyardgrass. Control of goosegrass and field sandbur often is less satisfactory, depending on the herbicide used. In all cases, read the herbicide label for more detailed information before using the product.


Post-Emergent Herbicides For Grassy Weed Controlgrassy weed control


Post-emergent herbicides are most effective when applied on annual or perennial grassy weeds soon after they have emerged from the soil, when they are young and actively growing. Since most post-emergent herbicides can be absorbed into the foliage, they must remain on the leaf surface for at least a day or two following application so it can be properly absorbed.


One of the best post-emergents for grassy weeds is MSMA Turf Herbicide. This product is often coined as a “crabgrass killer”. MSMA herbicide is most effective against young seedling weeds and can be applied only as a spray. Once the weeds become larger and more mature, MSMA is largely ineffective.


Other herbicides used for post-emergent control of crabgrass and other grassy weeds include quinclorac and fenoxaprop ethyl (sold in our stores as Acclaim Extra). Both of these herbicides can provide excellent control of seedling annual grasses, and fair to good control of more mature (larger) weeds. Due to their higher product cost they have traditionally been used only by professional lawn care operators but we have it available for the average homeowner to use and at affordable prices!


Our Suggested Grassy Weed Control Plan

Now that you know how some of the more common weeds thrive, it's time to take them on with a quality control product. The best way to take care of grassy weeds is with a solid pre-emergent herbicide that we recommend you apply in the springtime. This would prevent seed germination, keeping them from sprouting.  If annual grassy weeds have already sprouted than a control product like MSMA Target 6 Herbicide or  MSMA Turf Herbicide would work greatly.


Timing can be tricky though depending on the type of weed you have. If you have trouble identifying your weed or you have identified the weed and need information about the proper timing to treat your particular grassy weed problem, you can always call our number or email us at askapro@solutionsstores.com with a photo of your weed outbreak so we could best assist you with an effective control plan.

We here at Solutions have products for any phase of weed growth and have selective and non-selective options so depending on your preference, we can help you pick out the right product for you.
