Is your question if lawns can brown out from too much daylight? Because they certainly can, and e.g. in South Korea they were brown most of the summer. (in reality, it's probably more a mix dry, warmth and light).
Sure, but would daylight savings be the cause?
Are you missing that the quote is from a sentence listing example complaints and not actual affects of daylight saving?
I refuse to believe that people actually though the government was literally altering time itself.
