lawn turning brown
hi, i've been having this problem for years. i plant grass seed twice a year along with fertilizing twice a year. the grass initially looks great and then turns brown and dies. it seems to be worse on the more shaded side of the lawn. that side had some moss problems. which i used moss killer . i was wondering if i am overseeding or if the mower is killing it. i kind of don't think that it is the mower because it is more on one side of the lawn. any ideas?
