Yellow Grass

A typical sign that the grass has limited nutrition, especially Nitrogen, or limited water availability for healthy growth. This might also be a sign that the grass is starting to die out. It may attempt to set seed as a survival technique. A lack of adequate aeration, especially under waterlogged or wet conditions, can also produce a grass which is yellowing. Nematode damage can also result in turf yellowing; something which is called Yellow Patch.
