Reasons why Bermuda Grass can be a problem in St Augustine Lawns

Bermuda Grass is a challenging issue for St. Augustine lawns and can impact the aesthetics of gardens. Highlighting some reasons why Bermuda Grass invades St. Augustine lawns would give homeowners and gardeners insight into how to curb it.

  • 1. Bermuda Grass tolerates heat and drought better than St. Augustine turf; thus, it thrives exceptionally well in areas where water supply is scarce.
  • Bermuda grass spreads underground via rhizomes and stolons, additionally by producing seeds, it is an aggressive grower, spreading very quickly in optimal growing conditions.
  • The differences in growth rate between Bermuda grass and St Augustine Turf mean that when competing for space or nutrition, Bermuda grass has the upper hand because it grows faster than St. Augustine turf.

A proactive approach before Bermuda Grass becomes established involves proper maintenance practices such as sufficient irrigation to maintain healthy turf not susceptible to thinning or weak spots prone for invasion.

For instance, periodic use of pre-emergent herbicides can considerably alleviate infestation severity from either reducing seed dormancy or terminated root development to prevent its establishment.

Time is of utmost importance when dealing with lawn infections since delayed action worsens contamination and further damages a lawn leading ultimately to more expenses incurred on restoration. Thus proactivity by promptly addressing issues during grass invasion to protect your lawn investment will save time and money in the long run.

Say goodbye to Bermuda grass in St Augustine with these brutal methods that are sure to make your lawn look like a crime scene.

Methods to Kill Bermuda Grass in St Augustine

To get rid of Bermuda grass in St. Augustine, you can use several effective methods that include manual removal, herbicides, solarization, smothering, and soil sterilization. Each of these techniques offers a unique solution to the issue and you can choose the one that suits you best based on your budget, time, and effort.

Manual Removal

For removing Bermuda grass in St Augustine, one effective method is by physically pulling it out. This is commonly called ‘Hand Pulling’ and involves uprooting the unwanted grass manually from the turf.

Here’s a 6-step guide to Hand Pulling:

  1. Identify the areas where Bermuda grass has invaded your St Augustine lawn.
  2. Wear gloves to protect your hands.
  3. Get down on your knees and grasp clumps of Bermuda grass at its base.
  4. Gently but firmly pull the grass and its roots out of the soil.
  5. Repeat this process until all Bermuda grass has been removed from the infested area.
  6. Dispose of the uprooted plants properly as they may regrow if not disposed of correctly.

It’s important to note that Hand Pulling should be done during early-to-mid summer months when peak growth happens to prevent significant damage to St Augustine turf in other seasons. In addition to wearing gloves during Hand Pulling, you may use a small shovel or digger tool to loosen soil around clusters for an easier and faster process.

A landscaper once shared how she used Hand Pulling techniques to help her client control Bermuda grass spread while maintaining their lush St Augustine lawn – resulting in happy customers who praised her hard work.

If Bermuda grass was a person, herbicides would be the restraining order.


Using Chemical Compounds to Eradicate Bermuda Grass

When it comes to getting rid of Bermuda grass in your St Augustine lawn, the use of chemical compounds or herbicides can be an effective solution.

Here are some important points you need to know:

  • Choose a selective systemic herbicide that targets Bermuda grass while leaving your St Augustine turf unaffected.
  • Apply the herbicide during its active growth season for best results.
  • Be consistent with the application schedule as real progress may not be visible for 2-3 weeks after each treatment.
  • In addition to commercial herbicides, natural or organic options such as vinegar and table salt can also be used to kill Bermuda grass. However, they may damage not just the weeds but also neighboring plants and organisms in your lawn.
  • To ensure safer and more effective application, hire a professional lawn-care specialist before deciding on any particular chemical compound or natural remedy.

A Vital Precautionary Measure

It’s always best to wear protective gears like gloves, mask, shoe cover etc while using chemicals in proximity to living beings.

Non-Selective Herbicides

Non-Selective Herbicides are a potent solution to killing Bermuda grass in St. Augustine. Utilizing these herbicides will help eliminate the unwanted grass, but it also risks damaging other plants or greenery near the affected area.

Below is a table of the most commonly used Non-Selective Herbicides for killing Bermuda Grass:

Herbicide Name Active Ingredient Effects
Roundup Pro Weed Killer Concentrate Glyphosate Systemic absorption that inhibits production of essential proteins.
Southern Ag 2,4-D Amine Selective Weed Killer 2,4-Dichlorophenoxyacetic Acid Burning or wilting of leaves before systemically killing the plant.
Ortho GroundClear Vegetation Killer Concentrate Glyphosate and Pelargonic acid Absorbed by leaves and roots with effectiveness seen in hours.

It is important to keep in mind that Non-Selective Herbicides should only be used as directed on the label. Before applying, ensure that the herbicide chosen will not damage any nearby plants or vegetation.

Another precautionary measure to take when using Non-Selective Herbicides is to wear protective gear such as rubber gloves and eyewear.

Pro Tip: Non-Selective Herbicides work best during warm weather when the growth rate of Bermuda grass is at its peak.

Kill Bermuda grass the natural way with organic herbicides, because nothing says ‘I’m environmentally conscious’ like a dead lawn.

Organic Herbicides

Organic weed killers to eliminate the stubborn Bermuda grass in St Augustine can be useful. Here’s what you need to know about such solutions:

  1. These weed killers coat the grass and dry it up, depriving it of resources and water.
  2. This eco-friendly option doesn’t harm the surrounding plants, animals or soil.
  3. Corn gluten meal herbicide can gradually but effectively kill off Bermuda grass roots while promoting the growth of a healthier lawn in St Augustine.
  4. D-limonene organic herbicide is another helpful solution that dissolves prior chemicals from soil and targets only weeds.

It’s important to note that organic herbicides may not provide fast relief and may have limitations in combating certain types of Bermuda grass infestations.

Experts suggest that using these solutions alongside other remedial treatments in St Augustine, such as hand pulling or solarizing, can significantly improve results.

Through the controlled process of soil solarization, we can effectively eliminate Bermuda grass in St Augustine without using herbicides. The method involves covering the infested area with a clear plastic sheet and trapping the heat from the sun to raise the soil temperature, creating an environment that kills off weeds and other pathogens. In addition to being environmentally friendly, this technique is cost-effective and yields long-lasting results.

To achieve optimal soil temperatures for solarization, it is crucial to ensure that the plastic sheeting used is clear and securely anchored to prevent any air pockets. The best time for this method is during summer when temperatures are high. This technique also works best in areas with exposure to direct sunlight throughout most of the day.

During periods of less sunshine or lower temperatures, there might be a need to extend the duration of the solarization process for up to six weeks. To make sure no part of the lawn escapes treatment, it’s crucial to monitor the progress regularly and maintain consistent conditions under one-hundred percent coverage.

Pro Tip: Remove all debris on your lawn before soil solarization; it ensures maximum effectiveness by allowing heat penetration deep into your exposed ground surface, a necessary condition required for efficient weed control.

Nothing says ‘I love you’ to Bermuda grass like smothering it with a tarp – it’s like a cozy little hug, just with more death involved.


To deprive Bermuda grass of oxygen and sunlight, an effective method known as ‘covering’ can be used. This involves layering organic material such as compost or newspaper on top of the grass while ensuring complete coverage. By inhibiting Bermuda grass’s ability to grow and receive light, this technique is highly effective in eradicating it from St Augustine lawns.

In addition to the traditional smothering approach, plastic sheeting can also be an effective way to kill Bermuda grass. Laying a thick layer of plastic-sheeting directly on top of the grass will effectively cut off its access to sunlight and create an environment where it cannot thrive. However, it is essential to remove all vegetation before applying a plastic sheet.

It’s important to note that smothering may not completely kill all the stubborn grasses in one go. Apply this approach regularly until satisfactory results are achieved.

By using a smothering technique in his backyard garden, Mr. Johnson was able to remove a persistent patch of Bermuda grass that had been disrupting his otherwise diligent landscaping efforts for months.

Kill two birds with one stone (and a shovel) by sterilizing your soil and eliminating Bermuda grass at the same time.

Soil Sterilization

One effective method for eliminating Bermuda grass in St. Augustine is through the use of soil sterilization techniques. Soil sterilization is a process that involves the complete elimination of all living organisms in the soil, including weeds, disease-causing organisms, and beneficial microorganisms. This approach helps to create a clean slate for the growth of healthy grass without any competition from unwanted plants or harmful pathogens.

There are several ways to achieve soil sterilization, each with its unique advantages and disadvantages. One popular method involves heating the soil using steam or hot water to kill off all living organisms. This approach is particularly effective in controlling weed seeds and other pests that can cause damage to lawns and gardens.

Another method is through the use of chemicals such as herbicides and fumigants that target specific species of weeds and pests. While chemical treatments can be highly effective, they also have potential environmental impacts that must be considered.

Overall, soil sterilization techniques are an effective way to eliminate unwanted vegetation and ensure optimal growing conditions for desirable plants like St. Augustine grass. However, it’s important to carefully weigh the benefits and risks associated with different methods before choosing one that best fits your needs.

Say goodbye to Bermuda grass once and for all, because nobody wants their lawn looking like a mini golf course.

A neighbour once struggled to remove all remnants of Bermuda grass from his residential lawn but eventually succeeded by taking an integrated approach of herbicides, manual removal and careful overseeding with drought-tolerant St Augustine sod.

Say goodbye to Bermuda grass and hello to low-maintenance lawns with the power of landscape fabric and pre-emergent herbicides – your mower will thank you!

Use of Landscape Fabric or Pre-Emergent Herbicides

Using Barrier Materials or Pre-Emergent Herbicides to Halt the Growth of Bermuda Grass in St Augustine Lawns

To prevent Bermuda grass from re-growing in St Augustine lawns, utilizing barrier materials or pre-emergent herbicides can be an effective solution. Here are three points to consider:

  • Landscape fabric can be used as a barrier, blocking the growth of unwanted weeds and grasses.
  • Pre-emergent herbicides interrupt the germination process of the Bermuda grass seeds before they have a chance to sprout.
  • Herbicide should be applied only during optimal weather conditions for best results.

Additionally, it is essential to use caution with herbicides and follow manufacturer instructions carefully. It is worth noting that this approach requires consistency and patience as reapplication may be necessary. By following these steps, your desired lawn species will have space to grow healthily without competition from uninvited intruders.

An interesting fact: In 1912, the United States Department of Agriculture (USDA) introduced a grassed area between Independence Avenue and Washington Monument; It was one of DC’s earliest parks and grazelands at that time.

Remember, the only way to truly prevent Bermuda grass from re-growing is to sell your house and move to a concrete jungle.


Eliminating Bermuda grass in St. Augustine requires a comprehensive approach that must be adapted to the specific conditions of each lawn. Here are the steps that can be followed:

  1. It is essential to identify the type and extent of Bermuda grass infestation.
  2. One can choose from several effective methods of eradication, such as hand removal, chemical treatment, or solarization.

Lastly, it is crucial to maintain proper lawn care practices and prevent any re-infestation by taking preventive measures.

While Bermuda grass eradication can take time and effort, the results are worth it for a healthy and beautiful St. Augustine lawn. Investing in regular lawn maintenance such as mowing at the right height, watering adequately and correctly, fertilizing throughout the year are some excellent options to ensure a lush green lawn.

A common mistake while tackling weeds is blanket herbicide spraying across the entire lawn; however, experts suggest spot treatments for an accumulated effect using selective herbicides specifically designed for Bermuda grass control would give better results.

Pro Tip: Regular monitoring of your lawn helps identify weed infestations early on and tamp them down quickly before they go out of hand.
