Here are the things you can use to make a mixture of fertilizers.


Homemade lawn fertilizer with beer is very popular as it delivers nutrients to the grass and the bacteria. Since it is fermented, it is beneficial and helps in proper growth.

Baby shampoo

You can use mild baby shampoo but not antibacterial soap. The non-bacterial shampoo is suitable for grass, making the ground absorb more. This shampoo can also help the soil open up to soak in nutrients.


Ammonia is essential to provide nitrogen. You can find it in any grocery shop labeled as ammonia hydroxide. It is a mixture of Ammonia and water, which is also safe for household purposes and plants.

Try adding Ammonia as it is rich in nitrogen, and plants can’t live without nitrogen. Ammonia helps a lot in making a natural grass fertilizer homemade.

Club soda

Carbonated water is a source of carbon, oxygen, hydrogen, and good sodium like baking soda. It is helpful for growth and to make a deep green lawn due to high sugar.

Epsom salt

It is a source of magnesium and sulfate. Epsom salt is beneficial for plants and grass. Always use Epsom salt, not table salt, which might kill the grass.

Use Mouthwash

Sounds weird, but effective yet. Yes, you can use any cool mint-type mouthwash as a cheaper fungicide alternative.

Supergreen lawn tonic

Now let’s get into the central part to make a Supergreen lawn tonic. For this, take-

  • One bottle beer
  • 1 cup of baby shampoo
  • 1 cup of club soda
  • 1 cup ammonia
  • ½ cup Epsom salt
  • Minimum 38L water

Notes: This measure is for 1 sq.ft. lawn

Step 01: Mix them well with water in a big container with a lid to make cheap fertilizer for the lawn. Add the mixture to a hose-end sprayer like a 32 oz sprayer hose container.

Step 02: Now apply the fertilizers evenly and thinly on all parts of the lawn. Don’t let the nozzle linger in one place for a long time. Try to give some water lightly while Fertilizing. Using water during fertilization helps to feed the roots.

Step 03: Reapply the fertilizers every two weeks, maintaining the pH of the soil between 6 to 6.5. Please don’t put too much fertilizer as it can inhibit the growth of the grass. Put water along with fertilizers if it hasn’t rained for a long time. And try using it when the temperatures are below 85-90 degrees.

Do a test on whether they work well or not as different places have different climates. Monitor and keep a watch. In this way, you can learn more about how to fertilize the lawn yourself.

Precautions regarding fertilization-

  • Read the label before using every chemical product. Please pay close attention to how much Ammonia or alcohol is to be used and how long you can use it.
  • After applying the fertilizers, wait for 24-48 hours and avoid using the lawn. Especially pregnant women, kids, and pets have to be safe from it.
  • Don’t put too much fertilizer as over-fertilizing can burn the grass. Always follow the recommended amount.
  • Choose the organic fertilizer which is made from worm compost or manure. It, at a time, remains safe and provides nitrogen to the grass.
