Toadstools: If you see too many of these cropping up on your lawn you could have problems

Even the toughest grass species are vulnerable to disease, and even the most attentive gardeners can find their lawns falling victim to fungus and other parasites. In fact being too attentive can even be detrimental, for example applying too many nutrients can upset the ecology of the soil and actually create conditions favorable to an attack.

The reason why just about any patch of grass is susceptible to disease is that the fungus and other nasties that cause problems are actually present in the soil at all times, it’s only when the conditions are altered that it opens the flood gates to allow the fungus to move in and really make its presence known. As mentioned this can be because of too many nutrients, but it can also be due a lack of nutrients, soil pH, and a climate unsuitable for the grass species.
