There used to be a good guy on there who worked in the lawn care profession. I was wondering if anyone knew anything about how to properly maintain a lawn. I do the fertilizer in the spring, remove weeds...etc. And my lawn looks nothing short of outstanding from April until now. Then it starts to die in patches, turn brown and some starts to actually rot a little bit. Right now my yard has a fair number of mushrooms growing in it. I'm wondering what the mushrooms mean and what I should be doing to take care of my lawn better? I did just pick up another bag of Scott's Turf Builder to put down, should I be using anything else? Would aerating the yard help?
