What not to do to your yard

I usually fertilize the grass in the spring and the fall. I'll put down some grass seed during those times too, and my yard looks pretty good. This year I waited a little late to put down the spring fertilizer (Memorial Dayish) and the stuff I bought at Home Depot was more like hot weather fertilizer. I decided I would put some more down on the 4th of July, and the good news is my lawn is thick and green. The bad news is I have to mow every week regardless of rain and it clogs up my mower b/c it's so thick.
