My neighbor waters his lawn late at night like an idiot. I planted new grass and had many seedlings. They recently started dying over near his side of my yard (looks like rotting grass). I put down some bayer advanced fungus control, but I don't know that will do anything. Temp recently dropped a whole lot in the past few days. Was in the upper 80s prior, now upper 70's and about 50 degrees at night. Will that be enough? Is there anything I can do? Thanks!
