I have a 150 foot draining ditch that is filled with weeds and underbrush. It is impossible to mow and nearly impossible to weed eat. It looks even worse in the winter when the weeds die
and the clay dirt shows through. I have decided to line it with Tiger Lilies to make the ditch more attractive as well as protect it from erosion. Should I spray the whole thing with roundup before planting the Lilies or plant the Lilies amongst the weeds and let them naturally choke the weeds out?

It looks like the Joe Pye weed prefers moist soil. My drainage ditch often becomes bone dry
when there is little rain or when it is extremely hot so it may not do well for me. I like the idea of planting the tiger lilies along the outer edge of the ditch but I really need to get the weeds in the ditch under control. Is there a fast spreading ground cover that I can use that would tolerate dry conditions and getting wet occasionally? I'm adding some images to show how bad the ditch looks.
