I originally got the recipe from a garden guru named Jerry Baker. Then I heard that some former Golf Course groundskeepers were using it on their lawns at home. Good enough for me. All you need are five common household ingredients and a 10-gallon hose-end sprayer.
One full can of regular pop (any kind as long as it's not diet. Needs sugar!)
One full can of beer (no light beer) 12oz
1/2 Cup of Liquid dishwashing soap (do NOT use anti-bacterial dishwashing liquid)
1/2 Cup of household ammonia
1/2 Cup of mouthwash (any brand)
Pour into 10-gallon hose-end sprayer.
Attach to hose and water your lawn.
How Does It Work?
I'm not a scientist (and I don't play one on TV) but I hear that:
The liquid soap is a wetting agent, helping the formula penetrate the roots. It's important to not use anti-bacterial dishwashing liquid in the mixture as it will kill off important microbes in the lawn and soil that help"digest" thatch.
The ammonia promotes growth and turns your lawn green.
The mouthwash kills the bugs and grubs.
How do I explain wasting beer on the lawn to my neighbors?
Tell them it was a gift from your brother in law who doesn't live in Portland and so he thinks HIS favorite brand is drinkable. lol.
