Dethatch your lawn by raking up the dead grass.

Fertilize lawn and set dirt and grass seed if needed.

Fill a lawn sprayer with 1/2 container ammonia and 1/2 container beer.

Shake well and spray lawn.

Let sit for 24 hours.

The next day, fill your lawn sprayer with 1/3 portion liquid laundry detergent, 1/3 portion liquid dish detergent, and 1/3 portion mouthwash.

Repeat the detergent and mouthwash step every 3 weeks.

After the mouthwash, laundry detergent, and dish detergent step, let it sit 24 hours without watering.

Water as needed.

Repeat once a month.
