Lawn Fungi

[hazelcs]

hi my husband is driven mad to find after laying a new lawn last year that it now has mostly "silver birch" type fungi growing in various patches. As the new grass is actually in the driest part of the garden you would think least chance of a mould growing as not damp. Any ideas?

I can't picture the 'mould' you describe but have you tried using a lawn weedkiller on it.

I also cannot picture the mould,Have you got a Silver Birch tree near by which has been cut down.If you have rotting roots under the lawn you will get various types of fungi growing through it.Weed killer will not help,the only way is to dig down and remove the rotting roots.

However if that is not the case you could try Armillatox available from garden centers,it will not damage the grass if you follow instructions correctly.

Fungus is mostly lichen - Armillatox will kill it off.

No silver birch trees growing anywhere near but a number of larger shrubs - some about 20 odd years old - so their roots could be spreading away under the grassed area at the front but not so at the rear of the house.
Local garden centre's advice is to loosen up the soil by spiking and then brushing in lawn sand/ If we sort the soil then that will stop giving the lichen/fungi the soil they like. Work done so now it's a case of wait and see. Thanks for the various responses.
