Weed Prevention in Dwarf Mondo Grass
I planted some dwarf mondo grass that is doing a pretty good job of spreading. Last spring and summer though I got lots of broad leaf and grassy type weeds in it. In the areas that the mondo grass has become very dense its virtually impossible to manually pull them out.
Does anybody know of a way to kill this stuff without killing the mondo grass? I'm thinking of using a pre-emergent, but I don't want to do anything that will keep the mondo from spreading.
Any recommendations or experience greatly appreciated!
