Introduction: Easily Getting Rid of Dead Spots on Your Lawn, Effortlessly!

Picture of Easily Getting Rid of Dead Spots on Your Lawn, Effortlessly!

With one easy and pet safe item, you can get rid of dead brown dry spots on grass caused by pet urine. Read on for the big surprise!

Step 1: Materials

Picture of Materials

Beer! - it can be hot or cold, fresh or flat. Use a regular beer.
Not light beer, malt liquor or a wine cooler.

Beer has lots of fermented sugars and nutrients. A dead patch will absorb the sugars and nutrients thus helping the soil below. The beer acts as a fertilizer and provides nutrients to new grass growth. The beer will strengthen the grass and neutralize the nitrogen in pet urine. (Woo hoo, science!) Beer eliminates fungi, as well.

Continue on to see how it's done!

Step 2: Here We Go!!!

Picture of Here We Go!!!

Use 8 ounces for about a 10 inch spot. Pour beer directly on dry spot.

Give it a week.

Step 3: Follow Up...

Picture of Follow Up...

Check spot a week later for growth. Add more beer, if needed.

Continue until area is healed.

Step 4: Enjoy Your New Green Grass!

I am going to try this. DO you know how to get rid of deer?

Garretds7 (author)2017-06-06

Love the comments! Lol! I am going to try this. But I am gonna do a mix of something a man on YouTube does. I've got a feeling this boosts the beneficial microbes in the ground and helps the grass recuperate. A little coke, some beer (just some of it!). Leaving out the amononia. He uses this concoction to speed up the compost pile. The beneficial microbes go to town with the barley and sugars. I'm betting this happens with the beer. Thanks for the instructable! I have dead spots all over from our 18 year old dog. Funny thing, I've been routing him to go in a specific spot where weeds are! The urine doesn't seem to affect the frickin' weeds! Go figure! Lol!

this is a total waste of a good beer. use 1 TB epson salt/1 gal H2O. works just as well but you get to enjoy the beer!

pmann1 (author)2017-05-31

Simple as that? Looks like my beer bill is about to go up!

JamesGray38 (author)2017-05-29

Would it work if I drank the beer and peed on the grass?

pookiesmum (author)JamesGray382017-05-29

Nope. Tried it. You still have ammonia in you pee that is too strong for the grass. However....if you pee into a container and then leave it for at least 24 hours then you can use it on your grass. The excess ammonia evaporates and then bacteria does the rest!

betorobotics (author)2017-05-29

I have a great idea for all the cheapos who consider this a waste of beer. Next time you throw a party at your house and your friends leave a bunch of half opened bottles or cans of beer laying around, Just take that beer and pour it around your yard.

rbeech1 (author)2017-05-28

if I drink the beer and wait and hour and then pee on the spot it will have the same effect.

nonobadog (author)rbeech12017-05-28

You have to do this scientifically. Pee on the dead spot, then pee on a healthy spot as a positive control, then pee on the driveway as a negative control. Then of course you should pee on these spots at all your neighbors places so you have more statistical samples. That is the scientific method.

MikeC459 (author)nonobadog2017-05-29

This is by far the funniest (and most correct) comment I've read all day. Thanks for the laugh Nonobadog.

thundrepance (author)nonobadog2017-05-28

omigosh, you guys are killing me! ? i was going to say what a great idea this is, but started reading the comments; couldn't stop laughing! x^D

{pls ignore that "?" .... it was a laughing emoticon}

Russ2016 (author)rbeech12017-05-28

nope the effect will be different

RSanchezInc (author)2017-05-29

It seems like a waste of a good refreshing drink.

noteabaggersplz (author)2015-03-24

I make Kombucha tea. I wonder of the components of the fermented tea and sugars would work the same way?

dkimbril (author)noteabaggersplz2015-03-24

No it doesn't. Beer acting as a fertilizer is a myth.

cobaltxxxfusion (author)dkimbril2015-03-24

Thank you. Plants cannot take up sugars anyway. It gets into soil chemistry that is far too involved to cover here. It is chemically impossible.

You are correct, plants cannot take up the sugars. However, soil microbes can, and without those, the plants are not going to grow. ;)

Which microbes would that be and how do they help? Do you have facts or partial facts or shooting from the hip? Look people we can have healthy debate to learn from each other or act like kiddos. Just because someone may present a view or facts that differ from your own thinking, don't take it as a personal attack. Science of all types depends on this method.

No, I am speaking from a college education, a degree in horticulture and 30-odd years experience as a professional greenhouse grower, and granted, my knowledge in soil science is pretty limited to knowing it exists and what I need to know to take advantage of it in regards to plant growth. I do not profess to be an expert in the field, I am not a scientist, not too many professional growers are.

In a nutshell, there exists many species of beneficial, symbiotic bacteria known as rhizobacteria (one of millions of single-cell organisms referred to as microbes.) Rhizobacteria tend to concentrate on root surfaces (rhizo = root, although there are free-living species as well), they aid plants in fixing N (nitrogen) and in binding essential metals needed for plant growth (i.e. copper, iron, molybdenum etc.) In completely sterile soil with no rhizobacteria, plants are unable to take up essential nutrients and if the situation is not corrected, they will yellow and eventually die no matter how much fertilizer and water you apply to the effected plants (what you would need at that point is to employ a biofertilizer to fix the situation.)

Mostly what is happening here with using beer to reverse pet urine damage is called soil flushing. You can achieve the same effect faster using plain water. Urine is mostly urea (a form of nitrogen), and too much of it will burn plant roots, killing them (thus the dead spots in the lawn.) No roots means the plant cannot take up water, and if it can't do that, it dries up and dies. Beer has a lot of water in it, so it would flush away some of the urea. Beer also contains CO2 (carbon dioxide) which is essential to plants, they use it in photosynthesis (I'm going to assume at this point you paid attention in science class in school.) CO2 however is only used by the "above-ground" parts of the plant, not the roots (note that some plant's roots are also above ground, but for the purposes of this explanation, I won't address them.) Roots need O2 (oxygen) instead, so pouring a beer on them for the CO2 benefits would simply be a waste of beer. However beer also contains some trace minerals, so in theory, it would work in helping to re-condition soil that had been flushed by adding back some of those flushed away trace minerals, encouraging both the rhizobacteria to repopulate the effected area, and the grass to grow there again. Compost however, would work much better in that regard.

In short, there is no harm to pouring beer on dead spots in the lawn, there are some small benefits to it. There are however better methods to use, but in a pinch, beer won't hurt anything. Personally, I'd save the beer for myself instead, but I will not mock or naysay anyone who would like to experiment with, or use it. If it works for them, then that is all that counts.

I tried to keep things simple, however you wanted more science cobaltxxxfusion, so there you go. I hope you've learned something today.

AlienC3 (author)AmyLuthien2017-05-29

Dear Emy, I have been utterly exhausted with your wonderful comment, perfectly documented and backed by a technical and thorough explanation. However, beyond such great enlightenment, it dominates me the temptation to throw some beer (very cheap one) on the dry patch of my lawn. Will I be doomed?

Carol1023 (author)AmyLuthien2017-05-29

Yes, although this is an old comment, it has become pretty much common knowledge that soil with living organisms is much healthier than soil that is lacking them. Our soils (and our bodies) rely on many micro-organisms to function well, bacteria and fungus are often symbiotic with plants and actually bond to the roots and feed plants. There's a ton of new research in soil sciences, really cool stuff, and there's still a lot we don't understand. If beer helps the bare spots in my lawn, I'll use it, though I haven't had to try it yet, I sure wouldn't hesitate! It won't hurt anything, worst case scenario, I've wasted a beer!

Since I last posted here, I broke my upper arm very badly and I found that I got more relief from Arnica Montana as a homeopathic remedy to help with swelling and to allow me to sleep in spite of pain than I got relief from the narcotic pain meds that only made me crazy while I still hurt. Now I use her herbal remedy of Turmeric capsules to help the pain and swelling of my arthritis (along with Arnica at times too) and get more relief from that than from over the counter pain meds. Taking electrolytes after a busy day helps me rest at night and keeps my muscles a lot more comfortable than otc meds.

People talk about placebos, but I would think I'd expect the narcotic to help me more than a homeopathic, and it was quite disappointing. All it did was make me rather crazy and constipated! I would say this is the worst pain I've dealt with for the longest time in my whole life.

Be sensible, do your research, and experiment when its not likely to cause you harm and see what various herbs, homeopathics, etc. work well for you when you need them.

I know this comment is 2 years old, but I just wanted to say THANKS!

Geesh, thanks for keeping it simple. I think I just might be able to understand. "I hope you learned something" Come on, Really? Most of what you wrote was very well written and true. However Biofertilizer is just slow release, when it breaks down it is no different than any other fertilizer. Most beer do not contain live fungi and even if they did the dominant species would be the ones you mention in your post, and the CO2 is basically insignificant. Quacks like Jerry Baker, promote these curious methods that again have no fact to substantiate their clams. Have I learned something today? Yes, I have learned something and that people want to believe the ridiculous as true as if they have discovered some hidden secret. Beer will help wash the salts off the vegetation and might yet very insignificantly leach away some excess nitrogen but the salts in the urine case the damage. Simple fact is a glass of water would have the same effect as a beer Your snotty remarks just show your insecurity.

Ah, I see. You're just one of those people who's looking to start a fight on "teh interwebs." I was merely trying to teach you something, because there is a very obvious hole in your education, you however just want to be aggressive and well, snotty. Good luck with that, I'm sure it will take you far in life kiddo. As for Jerry Baker, I haven't a clue who he is.

GO LOOK UP JERRY BAKER'S BOOK"S. I have used many of his mixes, including lawn spraying with beer. They work very nice, just as he described in his books. Beer does indeed help good microbes, go here:

Thank you for being scientific. There exists too much magical thinking and superstitious nonsense, folk remedies, and etc. The proliferation is astonishing. I have college educated friends, two of them RNs, who use homeopathic remedies. they like that it is "natural". yikes! don't get me started : /

Perhaps they know something you don't? I have had great luck with homeopathic allergy medications. Also, I have seen very good results with using herbal compresses and salves for skin problems. A lot of modern medicine comes from using "folk remedies" and could easily lose some of the compounds that are useful in refining them. I would take advice from your RN buddies.

As for the beer helping dead spots in the lawn from animals, why would it have to be from nutrients? There's a lot of stuff that goes on besides whether or not lawns take up sugar. For example, I've had wonderful results getting new roots to grow in my orchids by using seaweed based products. There may be other compounds that actively help the grass recover.

Dear Carol1023. Please look up the definition of homeopathic on the internet. wikipedia is good. Homeopathic medications cannot work, because they are so diluted they contain NO active ingredients. and since your herbal meds are not regulated by the FDA, they don't even have to contain what they say on the label. And they may contain mercury and other toxins.These are the "snake oil" of the 21st century.

my nurse friend swears by these, & uses them to treat her family. on the other hand, they do absolutely nothing for me. <:^(

Yeah, strange, isn't it, that my allergies respond so well to the homeopathic treatment? I guess, even if it doesn't have any value, it sure doesn't have any side affects and I quit sneezing. Quite offensive to my scientific mind and training. :)

My herbal meds are compounds I make myself. I do know they have the herbs in them that I think they do, so I avoid that pitfall. I really did used to agree with you, as I said, I come from a very scientific background. However, as time as gone on and personal experience and the realization that an awful lot of "science" is just as junky as the unregulated stuff (poorly designed studies, hypothesizes that are self fulfilling, "science" paid for by drug companies with a stake in the findings - who then pay the FDA for approval, things like that), I've come to trust my own judgment as to what is really best for me. I'm afraid that the FDA is as full of snake oil as anyone, sad to say.

What is the name of this homeopathic treatment for allergies, that caused you to quit sneezing.

puggirl415 (author)Carol10232015-03-24

Between these 2 views on homeopathy or any folk, herbal or home remedy exists the idea of placebo. Far from being a negative the placebo effect can explain a lot of success with some of these alternative remedies people take. For my money I'd rather successfully "cure" myself of various maladies using the placebo effect positively than risk the side deleterious side effects of many of the scientifically created drugs from the western medical establishment. As Carol1023 stated there is a lot of junk science out there too.

For the skeptics I am not suggesting that we should shun the conventional doctors treatments when appropriate. If I have a broken bone or a head wound I will submit to the emergency room doctor's treatments. However, I may help myself along with herbal support for my body's immune system or to alleviate pain. Why does it have to be an either or situation?

elhnad (author)Carol10232015-03-24

they probably take it because it works for them. so what if you think it's placebo (or if it is placebo). I've learned to not knock something down just because the majority says it's impossible-especially when I haven't tried it or it deals with the human body, which is way more complex than most people say it is, much more so than designing machines or building something physical. their logic of "natural" may be off, but nobody should stand in their way; it's their choice, their money. the only warning is if they are so infatuated with homeopathy that their judgment of when to use standard protocols is clouded to the extreme.

Personally I recovered from something very terrible with homeopathic cell salts, and I used acupressure to relieve a few other ailments. To those who are trained to reflexively say "oh that's placebo", I ask: Did I not want the 10 things I tried that didn't fix me to work just as much as the one that finally did? We're increasingly being trained to distrust our own observations and feelings and depend on "experts". When you try a remedy, and you feel the effect is immediate, you should trust that instinct.

Everybody's body is different and reacts to what we consume differently. I totally agree with you about trying different aids to find the aid that works for you. Although it may work well for you, it may not work at all for another person. That is not the fault of the aid, but the problem of a different body. I use acetylsalicylic acid, I can't use ibuprofen or acetaminophen. Although they are aspirin substitutes, they work on me in negative ways. Other people can't use aspirin. If you have medical problem that "modern medicines" (drugs) do NOT work well for you, research alternative cures to find one that will work. Just be aware, there are snake oil cures and sellers out there ready to take advantage of you. Be intelligent, not gullible. With some problems, there are NO CURES or RELIEF!

Side note Allergies use a local honey! Quit buying pills! Lol

walter.warren1 (author)Carol10232015-03-24

We're asked to be positive and constructive here, so I'll just provide a very informative link. Take a look at this video from the 11:37 point on for a discussion about how homeopathic remedies work.

Germish06 (author)dkimbril2015-03-30

Its the nitrogen in beer that helps the grass. A couple other things but cant remember off the top of my head.

tovey (author)dkimbril2015-03-24

I read an article years ago, (Popular Mechanics or Popular Science) can't remember which. The article was about a golf course that sprayed low grade bear on the grounds to keep them rich and green.

Your comment therefore, is contrary to the practice of a professional landscaper taking care of a golf course.

If I'm not mistaken, this practice was done once a year, I which I could remember which mag it was. Maybe it was Mother Earth News?

killbox (author)noteabaggersplz2015-03-24

no, while the acidity of kombucha tea is low, its still effectively vinegar, and vinegar is known to kill off a variety of weeds and plants. i would not risk it. regular old tea or old coffee can help in moderation, especially if you have alkaline soil and acid loving plants.

chefspenser (author)2017-05-28

I use epson salt (MAGNESIUM SULFATE) to promote growth and makes everything greener...especailly palm trees, they really need it.

Carol1023 (author)chefspenser2017-05-29

Epson salts will work great if you have a Magnesium deficiency, for sure!

cdavenport (author)2017-05-28

Lots of science here, but nothing of any practical value. Let's talk alcohol abuse! Throwing away perfectly good beer? Where is the common sense in that?

mattcintosh (author)cdavenport2017-05-28

Lets say you have a party. The next morning there is a lot of half empty red cups and bottles lying around. Those can be used to fix the lawn.

FredT17 (author)2017-05-28

I mostly appreciated the detailed instructions. Very easy to follow.

Alaskan Bev (author)2017-05-28

Be sure that the grass in your yard is of legal age to drink. And it can be such a nuisance to have a bunch of drunk grass tripping all over the place...just sayin'...

LeslieB99 (author)2017-05-28

Realy? I try it

techydiy (author)2017-05-28

Interesting, I wonder if I give the dog the beer.

LarryF29 (author)2017-05-28

I believe it is against the law . It's a crime to waste perfectly good beer

dwleo (author)2017-05-28

Now he never said 'use good beer'. Besides a good IPA would be like steroids to the grass. This is a great solution to rid the world of Bud and Coors (and all the other 'plastic' beers)!
