We’ve written previously about beer as a compost starter.
Believe it or not, leftover beer also makes a handy spot-fertilizer for your yard, and it’s purely organic, since it’s the yeast in the beer that does the job. This works best for home-brewed beer, since you end up with a thin layer of yeast on the bottom of each bottle, but it works with commercial beers too. Just collect any dregs in a plastic gallon jug; a milk jug works fine. Once you have enough, you can transfer some to a sprayer bottle and spray the solution on places in your yard that have turned brown or aren’t growing well. The beer fertilizer will help the affected grass grow back in more fully. You can use it in your garden too, but it might not be as effective as other liquid fertilizers.
