I've bin cutting sod for 4 years now at this one stop.The guy likes it cut hi, 5 inches tall. He pumps it with water every day and feeds it every 2 mouths... He has the greenest yard in the neighborhood. What i want to know is, will this cause any problems with the life of the lawn? I noticed this year , there were more mushrooms and weeds in the lawn. Could cutting it so hi cause these problems? remember i bag this lawn!
