Last year, I killed off my front lawn completely, and reseeded it
with several types of creeping red fescue. (mostly epic and boreal) I
usually don't spend much time on the lawn, and don't even water it, but
I did end up spending a good amount of time and money on it. (including
about $100 a month watering it to help it get established)
The main point was to create a low growing, low maintenance
experimental lawn that would supposedly only need mowed half as often as
While the creeping red fescue does seem to be meeting this criteria,
unfortunately, I did not notice that the "shade mix" grass seed that I
used had PERENNIAL rye in it, not the annual rye that I thought it had.
I was thinking that the rye would dye off, and the fescue would fill
in during subsequent years through the rhizomes.
Instead, what I ended up with is maybe 20% of the lawn that is fast
growing, light yellow-green coarse blades that are almost twice as high
as everything else in a week. In effect, it looks a lot worse than the
lawn I had before I tried all of this.
Is there anything I can do to kill off the perennial rye that is
mixed in, without killing off all of the red fescue? I really don't
like the perennial rye, but also don't want to completely start over
