Despite all our best efforts, a lush Spring lawn almost always turns brownish-green by the end of the Summer. Bummed by the sight of a less than luscious yard? Keep in mind that a brown lawn is not a dead one — most grasses go into a Summer-dormancy as result of the extreme heat and dry temps in late July and August. A dead-looking lawn is no longer a sign of a green thumb gone wrong, instead it's a commitment to the environment. In fact, folks who are looking to keep their water usage down will intentionally let a lawn brown out in August. So don't fret if your lawn looks neglected during the dry, hot months, come September new life should spring back into the grass and it will go green again.
