Smooth crabgrass is the reason I fired the professionals who were supposed to keep it at bay via chemical warfare. They failed. The yard is pretty much Digitaria ischaemum from one end to the other.
And – I am not kidding – after a day spending hours digging it up, I still see it every time I close my eyes. It gets burned into my retinas somehow.
So I came up with a strategy to ward off the demons. When I close my eyes and see crabgrass, I pretend it's fireworks.
