Why does my lawn still get moss?

Moss is part of our climate, the amount of spores differs each year. To reduce the moss we need to remove the conditions it likes to grow in as much as possible. It needs moisture to grow in, so good drainage is a must. It enjoys shade so creating as much light as possible is benificial. It will grow where the grass sward is thin and weak, so healthy grass is important. The biggest culprit in encouraging moss is the mower! Cutting too short, especially in the autumn, and scalping high points will always increase the moss content. Regular aeration and scarification to remove and control thatch are also very important.
