Does Artificial Grass Kill or Encourage Bacterial Growth?

Does artificial grass help or hurt bacterial growth?

Within the last decade, compelling discussions have emerged surrounding the potential for negative health impacts as a result of long-term contact with synthetic turf systems – whether that be environmental health or the health of our athletes, children, and pets. Furthermore, a more prominent debate among industry professionals and researchers currently is the prevalence of bacterial growth on artificial grass surfaces.  

The following excerpt is an observation of studies that argue the efficacy of various antimicrobial control agents applied to turf – such as topical cleaning solutions or material additives incorporated during manufacturing – and the performance of non-treated synthetic grass with comparisons to natural sod.  

Antimicrobial Capabilities of Non-Treated Synthetic Turf vs. Natural Sod 

Interestingly, researchers have identified that the survival of bacteria on synthetic turf is largely reliant on the availability of nutrients, rather than simply an absence of an antimicrobial control agent – as reported by Waninger et al (2010) – implicating antimicrobial viability of even non-treated artificial grass systems in applications with reduced traffic and limited exposure to bodily secretions; this delineation is important, as bodily fluids such as mucus act as a source of food for bacteria and slightly increase their rate of survival.

For example, a residential front yard with artificial turf appears to present a lesser risk for harboring and producing microorganisms, while a high school football field poses a greater risk. Although, it is worth noting that even if bacteria can survive on turf while in a laboratory where nutrients are provided, it has not yet been proven that this survival could occur when subjected to outdoor elements (Waninger et al., 2010).  

Secondarily, bacterial colonization and reproduction are crippled by high surface temperatures and are even more susceptible to degeneration when only briefly exposed to UV light (Hardjawinata et al., 2005). During an experiment conducted by McNitt et al (2020) – where bacterial samples were introduced to both natural and synthetic grass, then measured – bacteria could be detected on both synthetic and natural grass samples under suboptimal growing conditions, but the bacterial survival rate rapidly decreased following slight increases in temperature and UV exposure.

Additionally, and anecdotally – as it was not intended to be a part McNitt’s study, a natural sod sample was measured as having higher counts of bacteria than the non-treated artificial turf sample. Researchers surmised this was possible because: 1) natural sod does not reach the same levels of surface temperature comparative to synthetic turf, 2) natural sod’s density may provide greater coverage from UV light, and 3) there is greater nutrient availability in natural sod.    

Silver Ion-Treated Synthetic Turf 

While increased surface temperatures and exposure to UV light are exceptional at inhibiting bacterial growth – even in the absence of an antibacterial additive – the transition into fall and winter seasons brings cooler temperatures and more cloud cover, giving bacteria a much better environment for reproduction.

Additionally, indoor applications with synthetic turf have controlled, cool ambient temperatures year-round and almost no exposure to UV light, making them slightly more susceptible to harboring bacteria as well. It is in these instances that antibacterial treatments to turf come into play.  

Due to the broad spectrum of its antibacterial capabilities and low toxicity to mammal cells, silver is a commonly used antibacterial agent in various materials and machinery, including both medical and nonmedical applications. Once bacteria comes into contact with ionized silver, the silver reacts by binding to the tissue proteins in bacteria, changing their cellular structure and nuclear membrane, resulting in cell distortion and the death of the unwanted organism.

Silver is so effective and highly active, that even in low concentrations it can maintain its potency. For example, fabrics with as low as 10 micrograms of silver ion per gram of fabric can sustain its effectiveness (Spielman-Sun et al., 2018). For optimum antibacterial activity and a more thorough cover of surface area, silver is usually integrated into multiple aspects of a finished product. Purchase Green antibacterial grasses will have silver ions infused in both the grass blades and backing material.   

 So, what’s the takeaway? 

Through various methods of measurement, researchers concluded that synthetic turf systems are not inherently ‘dirty’, but performed better than natural sod when observed in controlled studies. However, the survival of bacteria is largely reliant on the availability of nutrients, and while artificial grass has no organic matter for bacterial growth, bodily fluids such as mucus can be a nutrient source.

For this reason, applications indoors and/or with high traffic – either from kids, athletes, or pets – are recommended to utilize a combination of preventative measures to further inhibit the survival of harmful microorganism; this includes installing a silver-ion infused synthetic turf, applying a topical enzymatic cleaning solution as needed or on a semi-regular basis, and, where applicable and possible, a UV-C light treatment.

As an example, the “National Football League (NFL) does not require the treatment of outdoor playing fields for either [Staph] or Covid‐19, but do suggest indoor surfaces be treated with a spray disinfectant periodically and allow UV‐C light applications indoors as a supplement to spray applications” (McNitt et al., 2020).

In the wake of a pandemic, health and safety are top of mind. When choosing artificial grass for your projects, you can rest assured that minimal bacterial growth occurs with any synthetic turf and is easily killed with topical cleaners or even just UV-C and high-temperature exposure. Purchase Green’s antimicrobial artificial grasses go a step further with the addition of bacteria-destroying silver ions.

Purchase Green Artificial Grass Phoenix – What We’re Up To

We’ve been busy here at Purchase Green Artificial Grass Phoenix! Here’s what we’ve been up to.

At the beginning of March, we saddled up to the Maricopa County Home Show and had an awesome time meeting people and chatting about artificial grass. Thanks to everyone who came out, and we’ll see everyone at the next one!

We’re super excited about this installation we did for Chaparral High School in Scottsdale! These batting cages use the amazing Vista Sport, which has temperature-reducing Cool Yarn technology and a durable V-shape fiber to stand up to whatever those softballers can throw at it.

Summer will be upon us sooner than we realize, and it’s gonna be hot. Getting those artificial grasses that have Cool Yarn will be nicer than those that do not have it as it keeps the grass 10-20% cooler. It’s also important to note that while we’ll get to those triple-digit temperatures, our artificial grass doesn’t get hot from ambient temperature. So, even though it can (and will) be over 100 degrees this summer, if your artificial grass is shaded, then that won’t be a problem.


And we have an exciting offer for new contractors! We’ll be offering free delivery for new contractors’ first 3 orders! In addition to the free delivery, we’re also throwing in a free bottle of Turf Bomb.

Come stop by Purchase Green Artificial Grass Phoenix and see what else we have in store! We’re located at 2140 S. 7th Ave., Suite 100, Phoenix, AZ 85007. Or call us at 602-832-7245 if you have any questions!

Hello from Purchase Green Artificial Grass Dallas!

Hello from the PG Artificial Grass Dallas team! Thanks for checking out our blog.

As the weather starts to warm up in the coming months – and now that these spring storms have subsided – we’ll hopefully be getting outside a lot more. We’re looking forward to relaxing on a nice green lawn, no watering, no mowing. Here are some installations we’ve done lately that we know are going to be an absolute game-changer for this summer.

This shaded backyard is ideal for those hot and sunny summer days. Because our artificial grass doesn’t get hot from ambient temperature, it could be 100 degrees outside, but the shade from the trees will keep that grass from getting too hot. But, if you are worried about any bare feet or paws on that artificial grass, you can always opt for one of our Cool Yarn grasses, which keeps 10-20% cooler than other artificial grasses.

Getting artificial grass for backyard playgrounds is a no-brainer. This one is going to be a safer, more comfortable surface for kids playing and running around. And you’re not trading beauty for safety. Throw in some pavers, and you’ve got a backyard both the kids and the adults can enjoy.

And our final installation highlight is this 5-hole putting green. They definitely took advantage of our different-colored nylon flags, using our whole line of solid white, yellow, blue, and red flags. We were happy to bring some pops of color to this open area.

Thanks for reading, and if you have any project ideas of your own, don’t hesitate to contact us!

Come stop by Purchase Green Artificial Grass Dallas and see what we have in store! We’re located at 13908 Distribution Way, Farmers Branch, TX 75234. Or call us at 214-453-6820 if you have any questions!

Why Use Weed Barrier for Artificial Grass?

Once a site has been excavated, all debris removed, sprinklers capped, and the ground compacted, you will have the option of adding weed barrier for artificial grass.

Weed barrier can be laid either on top of or below the sub-base, or sometimes both. The benefit of installing weed barrier below the sub-base is that it helps to prevent base contamination, the mixing of sub-base and native soil. Because native soil expands and contracts with the changing temperatures, it’s important to make sure your sub-base layer is thick enough to maintain a strong hold for your artificial grass, in order to prevent bubbling or rippling. We recommend a 3-inch minimum excavation depth to help prevent weed growth, critters, and movement of your grass.

Though, if the native soil is rocky and hard as opposed to claylike, there’s not as much of a need for or benefit to installing weed barrier beneath the sub-base. If the native soil is harder, it’s suggested to install only one weed barrier layer on top of the base. And while weed barrier underlayment can help provide extra protection against weeds and gophers, it’s still not impossible for gophers to break through and weeds to protrude. Weeds can be tough to prevent if the soil was not excavated deep enough or if the sub-base is contaminated.

To install weed barrier, unroll the fabric and cover the entire surface, while also overlapping each layer edge by about 6 inches. Then, secure by hammering nongalvanized flathead nails or sod staples wherever necessary.

For more information on weed barrier for artificial grass, check out the video below. If you want to know if weed barrier is right for you, reach out to your local Purchase Green store, or hit up that live chat feature on our website.
