Even though the unsightly weeds may not actually kill the grass you have, you no doubt still want to get rid of it. According to the article, “How to Kill Moss,” at e-how, moss can be caused by a variety of factors, including unsuitable types of grass, drought, improper mowing, other cultural practices, a poor pH balance in your yard, too much shade, a lack of fertilizer, poor drainage, and an accumulation of thatch. Like all weeds, moss takes advantage of bare areas in your lawn. If you have moss, you have an unhealthy lawn. You will want to overpower the moss, if you want to strengthen your lawn.
According to the article, “Moss Control in Lawns,” at WSU, there are a variety of products that can be used to kill moss. These include products that have ferrous ammonium sulfate. Some of them include Moss-Out, Rid-Moss, and Moss-Kil. Safer’s, or other algae and moss killing soaps, may also be used. These products are safe for the environment. If you use the products, you will actually be using sulfur and iron, which are essential ingredients for grass. They also improve the color in grass.
You should know, however that killing moss is not enough. You will also have to work to solve the problems that caused it in the first place, or it will reappear. You do first need to kill the moss. Your next step is to detach and rake out all the dead moss. After that, you need to add new grass seed to the bare areas.

This will not only kill moss, it will also prevent it from returning.
