You Should Probably Wait Until After Storms Pass to Cut Your Grass, and Here’s Why
Last year, a few days before Tropical Storm Barry came through Acadiana, I was cutting my grass and thought "Ya know, I wonder if I should wait...maybe the taller grass might help hold back water". Well, I figured I was crazy because I am but, as it turns out I was actually kind of on to something.
The Facebook page The Urban Naturalist says that indeed, longer grass can possibly help you to avoid potential flooding. They say that "If everyone waited to cut the grass until after, we could potentially hold a lot more water in our soil by letting nature help us out."
This makes sense to me. Also, it can help to keep the drains a little emptier and free of yard clippings.
So if you've been stressing with your storm prep wondering when you'll find the time to get the yard done, don't sweat it. Leave it long!
