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





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

About: I enjoy making things. My making them is usually based on necessity, the fact that it doesn't exist, and/or buying it pre-done would be way more expensive. I like all kinds of projects and find this site a v...

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

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!!!

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

Give it a week.

Step 3: 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!

That's it!

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

    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!

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

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

    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!

    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.

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

    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.

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

    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

    nope the effect will be different

    It seems like a waste of a good refreshing drink.

    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.
