i have heard that grasses of that type seem to take advantage of poor soil..so if the soil is improved and heavily mulched you may find that it will eventually die out I hope so for your sake as that would be a lot of land to dig all the grass out of..(which I have to do here)
It would give a normal human mental abilities to rival mine. To think it is just a tiny ad:
