Lay down aged cow manure as a top dressing over recently mowed grass. Use bagged commercial aged manure or buy from a reputable bulk dealer. Manure can be used to top dress grass once or twice a year, with the first application in the early spring and the second in the early fall.
However, unlike cow manure, you canât buy it bagged. Although horse manure breaks down faster than cow manure, it still should be well composted before using it on a garden during the growing season. Manure from sheep and goats is easy to handle. Sheep and goats produce better manure than cows and horses.
