I have recently laid a turf lawn and find I have a sizeable patch of fungi growing in it how do I get rid of it please.
I'm unsure whether you have one of the fungal diseases that affect lawns or you have mushrooms popping up. There are many products at your local garden or hardware store to address fungal diseases. Fungal disease may indicate overwatering or poor drainage so look for standing water or soggy soil. Here is more info: https://www.gardeningknowhow.com/lawn-care/lgen/grass-fungus.htm
