Fairy rings, also called elf rings or pixie rings, are practically large rings of mushrooms that appear and thrive on lawns. The appearance and the growth of the rings is favoured by the presence of excessive moisture, then, when the fungus reaches a certain size, it starts releasing a nutrient-rich substance that leads to the excessive growth of the grass surrounding the mushrooms. The phenomenon looks strange, but it is relatively easy to get rid of – here are some tips:
- A suitable fungicide – natural control for the problem does not exist, but there are many efficient fungicides available. Most of them need to be dissolved in water, then the mix should be applied on the affected lawn area. The process should be repeated as needed, until the white mushrooms disappear and the thickness of the turf also returns to normal;
- Prevention and care – the fungus grows in moisture-rich areas, therefore limiting the amount of moisture on the soil surface will create an unfavourable environment for the mushroom. Excessive thatch absorbs moisture and keeps it in as well, so make sure to remove it thoroughly. Aerating the lawn also helps a lot, so make sure that the soil on your turf is never compacted.
