I have one account whos backyard is outragious! I cut it on a 10 day schedule. Her front and side are normal growth but the back yard will grow a foot in 10 days. I just went out to cut it today after the long winter. The front grass grew about .5" and the back was literally 3ft in some spots. The back is mainly weeds. She does have a dog back there which leaves me to believe he is fertilizing the lawn. I dont want to lose her because I also have her daughters lawn. Is there anyway to slow down the growth to make it easier on myself and not harm the dog?
