I am excited to share this post with you today! This is a cheap, easy and very effective homemade lawn food that you can use in place of fertilizer.
One of our most viewed posts last year was this homemade plant food recipe (click here to check it out).
What readers enjoyed most, was the science backed aspect of how it worked!
I love hearing all of your success stories on it too! In fact, my father in law uses this exclusively in his garden now.
First, let’s talk about this recipe, then we will share with you the amazing chemistry behind why this works so well!
Remember to always test small areas first before use. Please use caution around other plants, this is ONLY for grass!
PIN THIS: Easy Homemade Lawn Food
1 bottle of beer (it can be anything you have!)
1 cup mild baby shampoo (like THIS one, DO NOT use anti-bacterial)
1 cup club soda (any type you have or find for cheap)
¼ cup Epsom (NOT scented, like this one)
1 cup household ammonia (same as ammonium hydroxide, like this one)
Hose sprayer with settings (this is my favorite one)
Check out this video on putting it all together! Feel free to add us to Instagram or snapchat (alexisroch) for more videos and behind the scenes.
First, combine ingredients into a big jug (I am using a leftover Silk almond milk bottle). Make sure it is something with a lid.
For ventilation, mix this up outside or a place with air flow (like near an open window).
Cap the lid, then add all the ingredients to a 32 oz sprayer hose container (this one is the best and affordable).
***Make sure to set it no more than 3 or 4 oz per gallon!
Next, spray evenly over your lawn. You can water within a few minutes after application. The more you water while using this fertilizer, the more the solution will soak into the soil and feed roots.
Apply every 2-3 weeks when daytime temperatures are below 90 degrees. If you aren’t getting rain, make sure to water your lawn while using this.
This amount will cover a small yard using the hose sprayer. If you get a lot of rain or water often, you can use this to do 1/2 of your yard and make another bottle for the other half. For large yards, you will need to make a few batches.
Why this Homemade Lawn Food Recipe Works:
Beer is a unique item to add to your soil. Since it is fermented, it adds beneficial chemicals to the soil that aide in healthy bacteria growth. It also distributes nutrients to the grass.
If you have treated your lawn with chemicals before, beer can help restore the natural bacteria. Do not use any other alcoholic beverage like wine, liquor, or other drinks!
Mild Baby Shampoo
The key to this is allowing the homemade lawn food to adhere to the soil and grass, and it also helps the soil open up to soak in nutrients. Make sure to NOT sure anti-bacterial soap. You want to keep all the natural bacteria. I have found baby shampoo to be the most mild form of soap without suffocating the grass. Remember this homemade weed killer? It contained dish soap which allowed the solution to stick, and helped the plant to absorb the vinegar, salt, and arthritis rub which killed it quickly.
This works the same way, but we are using a gentle soap and helping the soil and grass absorb vital nutrients.
Club soda is another unique option. Carbonated water is a fantastic source of carbon, oxygen, hydrogen, good sodium like sodium bicarbonate (baking soda). This is very important for grass growth and helps for a deep green lawn.
Chemist Tip: I have read about people using sprite or coke for plants…it is the same principle that helps this work, but those drinks contain a large amount of sugar. This isn’t good for soil and attracts bugs. Avoid those problems by using club soda instead!
Grass and soil benefit from magnesium and sulfate. Epsom salt is a great way to get a deeper green for plants and grass.
I have had questions about ammonia in the past. To clarify this is HOUSEHOLD ammonia you find in the cleaning section of your grocery store (like this one). The label will read ammonium hydroxide. Ammonium hydroxide is a solution of ammonia and water which means it will be safe and diluted for household use. It is one of the best ways to get a large dose of nitrogen to plants!
I did a small portion in a few patches of our back field that have never been treated so I could show you a before and after. What I noticed most is the grass gets a deeper green, and the grass starts growing thicker!
FAQs on Making this Homemade Lawn Food
What if I don’t want to buy beer or don’t have any?
This solution CAN work without the beer, but it really helps with soil quality which helps grass grow better. I recommend using it for the full benefits of this homemade lawn fertilizer.
What if it’s really hot outside?
As with all fertilizers, even store-bought, you don’t want to use this when temperatures are above 90 degrees. Nitrogen can scorch grass in extremely hot weather. That is why spring is such a great time of year to feed your lawn!
What if I don’t have that spray attachment you mention?
This attachment is the easiest way to use a liquid fertilizer. You can also add 3 oz of the fertilizer to one gallon of water. Carefully water over the lawn with this. Just be cautious to evenly distribute over the lawn.
What if I don’t like using ammonia?
The most important aspect of this homemade fertilizer is the nitrogen content. The easiest way to get a large does of nitrogen in the home is from household ammonia. I don’t like using ammonia for cleaning since many of my family members have breathing issues. So, I only use it for outdoor things like this. It is very safe outside and will not harm anything! It is much safer than many store-bought fertilizers.
Also, I have been using the same bottle of household ammonia for over a year since I only use it for this plant food and this lawn food.
Can I use any baby shampoo?
YES! Get the cheapest you can find, it doesn’t need to be anything fancy. Just remember to make sure it is NOT anti-bacterial 🙂
Enjoy feeding your lawn!
