I dont do any fert. but all of my accounts have brown patch and I was wondering will it just go away in the spring/summer? Most of my customers have fert. companies service them, but they are all asking what will become of there lawn in the summer? In one subdivison all of the sprinkler systems are junk and are leaking all of the time, I inform them of the problem, but they dont seem to care. Anyways the point of this is will brown patch do damage to their lawns...All of them are st.aug.
