Toadstools in lawn
By Charles

Having had our garden landscaped with new lawn turf laid we find patches of small toadstools growing through. There was no such growth in that area pre new turf ( previous turf was > 10 years old ) and, as far as we know, no trees under the turf. How can I treat the fungus without excavating the lawn is there a top treatment that won't damage the new lawn?

You seem to have imported some mycelium along with the turf...could be a big problem ...or a small one if you've caught it early enough. I concur with Funky dunky, good luck.

There are many types of toadstools capable of growing in turf, the usual cause is buried organic debris and removing this will often eliminate a small patch. If you've got something like a fairy ring then its more of a problem and the only real answer is to remove the turf and topsoil to a depth of 1ft. The excavation should also extend 1ft beyond the inner and outer edges of the ring and all earth moved well away from the lawn taking care not to spill any. Fill with clean topsoil and re-turf. But if its only small patches you should not have to much of a problem.
