mushrooms in front yard lawn

My front yard is a disaster with mushrooms in the lawn area and most of the proper grass has been replaced by feral grasses and weeds. Please provide the steps to rectify the situation. Thanks…

Mushrooms in yard, lots!!!

live in niagara peninsula, st. catharines, very similar climate to toronto, have heard I can use potassium bicarbonate to kill them, was going to start in the spring, how much do I use, and where do I get it from?…
