I bet they were thinking about the fact that it would re-seed and insure an established grass in the ditch to prevent erosion.....BAD IDEA!! Like txboardog mentioned, they just planted a non-native wildlife attractant along the side of a very rural high-speed road in the woods. All this makes for is a recipe for disaster. I imagine that anytime now you will start to see dead deer on the side of the same road as does start looking for extra food so they can take care of their little ones. I bet they will be by to mow it soon too, which means next year you will just have a better crop
