Why is Bermuda Grass So Hard to Keep Out of My Fescue?

how to kill bermuda grass in fescue
You’re facing an uphill battle when it comes to keeping Bermuda grass out of your Fescue lawn. This warm-season grass grows aggressively and competes with cool-season turf, so you need a strategy that involves more than just mowing the lawn short.

You’ll want to employ multiple tactics in order to win this Bermuda Turf War:

Solarizing and choking the weed out.
Creating physical barriers.
Using chemical warfare with Ornamec or Triyclopyr Ester herbicides.
Getting defensive by aerating and overseeding your Fescue regularly.

Bermuda Grass Grows Aggressively

You’ll find that Bermuda grass can quickly take over your fescue lawn, stealing the show and taking no prisoners. This turf war requires a strategy to effectively control this aggressive weed.

Herbicide alternatives, fertilizer strategies, weed control solutions, overseeding techniques and optimal mowing practices are all essential components in winning this battle.

To maximize success, use an herbicide like Ornamec Over-The-Top or Turflon Ester, combined with proper watering techniques, fertilization schedules and regular mowing habits.

If you follow these steps carefully, you’ll achieve a healthy balance between the two species for many years.

Cool Season

To keep your cool season lawn looking its best, you’ll need to make sure it receives the right amount of watering and fertilization. Control weeds with targeted herbicides like Ornamec Over-The-Top or Turflon Ester. One homeowner saw great results with these two products for maintaining a healthy balance between their fescue and bermuda grasses.

Weed prevention requires applying a selective herbicide like Ornamec or Turflon Ester, specifically designed for killing Bermuda grass in Fescue lawns. Grass mixing is an issue that needs careful attention. Bermuda grass tends to dominate over Fescue if not controlled properly. Soil management and fertilizing strategies are crucial.

Mowing practices should focus on maintaining optimal height for the Fescue, while making it difficult for Bermuda to thrive. Spread clear plastic sheets over affected areas during hot seasons, to help eliminate any remaining roots left behind by dead weed plants. This is known as the solarization effect. Alternatively, use horticultural vinegar instead of chemicals, although its effects might take longer.

The key is being diligent about monitoring your lawn’s progress, and being patient. With consistent attention to these practices, you can rid your Fescue lawn of Bermuda grass weeds and maintain a healthy-looking lawn all year round.

Bermuda Turf War Strategy 1: Solarization and Choking

Take control of the turf war and get your Fescue lawn looking its best. Utilize solarization techniques and choke out any remaining weeds with targeted herbicides.

Create drought conditions to weaken the weeds. Use weed control through biological methods such as mowing and fertilizing. Then apply a glyphosate herbicide. Follow this up with an application of fenoxaprop or Turflon Ester. This will target the bermuda grass without damaging other plants.

With this strategy, you can kill Bermuda grass while allowing your Fescue to thrive!


You can outshine the weeds with solarization, a technique that uses heat from the sun to weaken undesirable plants and give your Fescue lawn an extra boost. It’s an organic control method that involves covering your lawn with clear plastic to trap sunlight and raise soil temperatures high enough to kill weed seeds, pests, and diseases. This helps increase plant diversity by eliminating competition for resources like water, light, and nutrients.

To prepare: mow your grass as short as possible without scalping it down to dirt level or damaging its roots. Then remove any debris like rocks or sticks from the surface of your lawn and till it lightly to create air pockets beneath the plastic cover. Heat can accumulate most effectively during summer months when bermuda grass thrives best.

Preventative measures:

  • Mow regularly
  • Water properly
  • Add organic matter, such as composted leaves or manure, to the soil after tilling

Dormant seeding:

  • Sow in late fall/early winter
  • Choose appropriate seed mixtures

Soil prep:

  • Test pH levels
  • Add compost/mulch


  • Ornamec Over-The-Top/Turflon Ester

Lay thick sheets of transparent polyethylene film over the area being treated. This creates a greenhouse effect under direct sunlight, making the temperature rise and eventually killing off the unwanted growth within a few weeks, depending on the weather conditions at the time applied. It’s effective against all types, including Bermuda grass.

Remember this is only one tool available in the arsenal necessary for combating pesky weeds invading fescue turf. Be sure to use other preventative measures mentioned earlier, while using herbicides sparingly according to the instructions provided on the label for usage and coverage rates, for optimal results and long-term maintenance success in keeping invasive species at bay.

Choking Bermuda Grass

Take control of your lawn and give your Fescue the advantage it needs to thrive by choking out unwanted weeds like Bermuda grass. Mow at 3-4 inches for optimal foliage health. Soil ameliorate with organic matter like compost or topsoil. Over seed annually to fill in any bare patches. Ensure fertilizer use is appropriate based on soil tests and irrigation schedules are followed. Consider using glyphosate-based herbicides or other weed killers specifically formulated for controlling Bermuda Grass in Fescue lawns like Ornamec Over The Top Herbicide or Turflon Ester Ultra Specialty Herbicide.

Bermuda Turf War Strategy 2: Create a Physical Barrier

Fight the battle for your lawn by creating an impenetrable physical barrier. Natural predators, planting habits, soil type, climate adaptation, cultural practices, and landscape ground cover tarp can all help. Herbicide usage is a great option; fenoxaprop-ethyl and glyphosate both contain a main ingredient that can effectively kill Bermuda grass without harming Fescue. Use these strategies to ensure your turf war against Bermuda is won!

Bermuda Turf War Strategy 3: Chemical Warfare

Take the battle to Bermuda with chemical warfare. Use herbicides to take control of your lawn without harming your Fescue. Managing infestations is key. Look into pre-emergent solutions, re-seeding strategies and fertilizing tactics for weed prevention.

Options like fenoxaprop or other labeled herbicide options will create a chemical barrier between the two types of turfgrass, targeting only broad spectrum weeds such as Bermuda Grass – which are difficult to manage otherwise.

Diligent applications and patience should give you control over both grasses on your property, allowing your Fescue Lawn some room to breathe.


Arm yourself with Ornamec Over-The-Top and Turflon Ester – powerful herbicides – to regain control of your lawn and make it a haven for Fescue.

It’s important to not only understand how much herbicide should be used, but also when it should be used, so you don’t apply too little or too much of these chemicals onto your yard. Follow all instructions carefully before use!

Borders and Barriers

Borders and Barriers
Building a barrier between your fescue and Bermuda grass can be key to keeping them in harmony, like two sides of the same coin. Reseeding techniques are one method for establishing these barriers and helping establish thick stands of Fescue. Mowing strategies such as raising mower heights on taller blades are further helpful methods when doing reseeding. Fertilizers solutions may also need adjusting since healthy turfgrass requires more fertility than weeds do. Soil maintenance can also aid in this process; adding organic matter increases water-holding capacity. Lastly, using selective herbicides with active ingredients like fenoxaprop helps control existing weeds without damaging established grasses at lower rates.

This helps promote desired plants over undesirable ones, and gives you better suppression of unwanted vegetation within flowerbeds whilst protecting desired species throughout the year.


To control bermuda in your fescue lawn, herbicides can be a useful tool. Glyphosate and Fenoxaprop are two of the most commonly used herbicides for this purpose. Glyphosate is non-selective and kills anything it comes into contact with, so special care must be taken to avoid harming other plants when applying it. Its broad spectrum control makes it great for killing grassy weeds like Bermuda Grass in Fescue Lawns.

Fenoxaprop is another effective option that targets annual bluegrass without damaging or affecting the surrounding desirable grasses like Fescue. Crabgrass Control products contain a pre emergent weed killer which prevents germination of crabgrass seeds before they become established – these can also help reduce some pressure from Bermuda on your turf as well!

Additionally, natural remedies such as vinegar or boiling water have been known to work on small patches of Bermuda Grass but may not provide sufficient coverage if you have larger areas affected by this pesky weed.

As an additional layer of defense against Bermudagrass invasion into fescues lawns, consider using weed resistance strategies such as proper mowing height (2-3 inches), fertilizing at proper times (early spring/fall) and watering deeply/infrequently instead of shallowly/frequently – all favor encouraging strong healthy growth rate from desired species over any potential invaders while reducing stress levels within turf overall environment, thus making it more difficult for weedy competitors including bermudagrass.

Lastly, keep in mind that multiple applications may be necessary. Herbicide application should begin early spring followed by a second one during Sept./Oct., although hot season applications should be avoided due to increased risk associated with hotter temperatures.

Glyphosate – Non-selective herbicide ideal for killing grasseweds like Bermudagrass on Fesisure Lawns

Fenoxaprop – Selectively target Annual Bluegrasses without harming surrounding desirables grasses

Crabgrass Control products – Contain pre emergent Weed Killer preventing Germination od Crabsgram Seeds

Natural Remedies – Vinegar & Boiling Water applied directly onto small patches og Bermugdangras works wonders

Weed Resistance Strategies – Proper Mowing Height, fertilizing & watering activities favoring desired species over any potemtial Invaders.


To outcompete Bermuda grass in a Fescue lawn, be persistent and proactive with the right herbicide approach.
