There are several types of fairy ring – most are not harmful, just unsightly. A well-fed lawn can mask the evidence of an un-harmful fairy ring. A grade one fairy ring is a problem disease and control is difficult – usually the removal of the lawn and re-turfing is the only remedy. Good feeding, scarification and aeration can prevent their occurrence.
Mushrooms / Toadstools
Toadstools are not harmful to the lawn (unlike fairy rings). Long periods of rainy weather may lead to the growth of mushrooms in your lawn. To remove; hand pick the heads away wearing gloves and brush the area with a besom broom to prevent sporing which leads to infestation.
Red-thread shows as light brown spots on the turf which have a reddish appearance. It is a fungal disease and occurs mostly during or after very wet weather usually during the summer and autumn months. Regular LawnHopper® treatments as well as annual scarification and aeration can help prevent the occurrence of red-thread.
Lichens thrive in poorly drained lawns and are often found under the shade of over-hanging trees. Lichen appears as a blackish leaf-like structure that grows through turf. Aerating the lawn each winter helps with surface drainage.
Fusarium Patch / Snow Mould
This becomes apparent in autumn and spring where brown patches appear with the edges covered in pink or white mould. It can be found particularly on poorly drained lawns. It is sometimes very noticeable after snow thaws. Annual aeration can help with this problem as it helps relieve compaction.
