Potassium salt from fatty acids is known to kill different types of moss, according to Garden Guides. Zinc is another moss killer, and it comes in different forms such as zinc-copper sulfate and zinc chloride. One particular zinc-based solution is zinc chloride at a 13 percent concentrate in powder
Alleviating damp, shady conditions and physical removal of moss are natural ways to kill it. Moss grows in yards as a result of moisture, shade and poorly maintained lawns.
Low-altitude pikas survive by eating moss, but very few other animals can do so because moss is a very poor-quality food, says National Geographic.
