Full Answer

  1. Mix the ingredients properly

    In a large bowl, combine one full bottle of beer, one can of soda, 1/2 cup of mouthwash, 1/2 cup of ammonia and 1/2 cup of dish soap. Do not use antibacterial soap. If you are fertilizing a new lawn, enhance the potassium levels by adding 1/2 cup of concentrated sea minerals. This fertilizer increases the amount of nitrogen and nitrates while also acting as a natural pesticide.

  2. Apply the fertilizer

    Fill a hose applicator with the fertilizer, and attach it to the hose. Cover the lawn evenly with the solution, applying it using a side-to-side motion. The fertilizer must be diluted through the hose to prevent chemical burns. Another way to apply fertilizer is to use a sprinkler system that has a storage tank for fertilizer use. Follow the manufacturer's directions when using this option.

  3. Fertilize as needed

    In Northern areas, apply the fertilizer during the fall. Otherwise fertilize the lawn before the rainy season begins for best results.
