Fifty or so inches of rain in just a few days is enough to turn any lawn into a soggy mess. And if poor drainage has left puddles where there ought to be tufts of grass, you might just have a new outdoor project on your hands.
Never mind that grass isn’t meant to live under water for days on end. It’s also not meant to be a filter for all kinds of toxins – hydrocarbon contamination or even sewage – that floated in with floodwaters.
Zach Buchanan, operations manager at Buchanan’s Native Plants, said Hurricane Harvey’s heavy rains and floodwaters will stress virtually every lawn and landscape. How they react to that stress will vary.
So keep an eye on your yard, document when changes happen and how quickly they spread.
