I mow lawns, but don't do any commercial fertilizing. I fertilize my own personal lawn. The lawn had been looking great all year. I have been using a Vigoro Fertizer 5 step fertizing program and have applied the early spring, late spring and early summer treatments so far. The last couple of weeks the lawn is getting spotty with weeds and or grab grass, I am not sure. (see photos) Does anyone have any ideas of what is going on what it is and what I can do about it? Can all the rain we've been gettin in the Northeast have soming to do with it? Thanks in advance for any help.
