How to Make a Weed-and-Feed Lawn Care

Pour the can of soda and beer into a hose-end sprayer. Both the beer and the soda will encourage important microbial activity in your lawn. The 10-gallon size is the ideal sprayer, but you can use one of another size. Anything smaller, however, and you may need to reduce the amount of liquid you produce, as it may not fit.

Add the dish-washing soap to the soda and beer mixture. It is vital, though, you only use regular liquid soap as opposed to anti-bacterial, as anti-bacterial will kill off vital microbes in the soil needed for it to grow well.

Pour in the ammonia and mouthwash to the mixture and shake well so all the ingredients can mix. The ammonia will break down into nitrates which will feed the lawn, and the mouthwash will kill bugs and grubs because of its alcohol content.

Attach the garden hose to the hose-end sprayer and spray evenly over the lawn in either early morning or evening. The lawn feed should be used every three weeks during the summer months or when there has been little rain.
