southern MN | Your goal is to not kill established grass, if I am reading right.
Liberty will hurt grasses pretty good in the high heat and humidity of mid summer. It is not a good grass killer tho, can’t rely on t all the time.
In the cool of spring, I would think it would bleach out a waterway, but not kill it outright.
So..... I’m scared to answer the question.
I would rather not drive right through a waterway with Liberty.
I wouldn’t be afraid of drift or catching corners of it in a cool spring application at all.
