When your lawn starts looking brown, spotty or full of weeds, that could mean it needs some fertilizer. There are many types of synthetic fertilizers for lawns, but if your children and pets like to play on the grass, you should think twice about dumping chemicals in your yard. Grass needs nitrogen-rich soil in order to thrive, and making your own organic lawn fertilizer is a much safer way to get the lush green lawn you want.
Put 2 or 3 lbs. of manure into a burlap sack, and tie it shut with a rope. The manure can be fresh or composted, but it must come from a grazing animal like a cow, sheep or horse.
Fill a large bucket with warm water, and place the burlap sack in the water. Set the bucket in a sunny place for at least one week.
Take the sack out of the water when the water is dark brown and cloudy. Hold the sack over the bucket until all the water drains out of it. Dispose of the manure.
Dilute the manure tea before applying it to the lawn because it is a very nitrogen-rich solution that can burn your grass if used full strength. Use about 1 cup of manure tea to 1 gallon of water. Mix the tea and water in your sprayer.
Spray your manure tea mixture over your entire lawn before watering. Use enough solution to soak all your grass.
