I'm lucky enough to have little blue stem and buffalo grass make up a lot of areas in my lawn. However it a lot of other areas, there is enough Bermuda mixed in for it to be a real pain.
I'm continually taking over lawn areas for raised beds and/or beds at ground level.
So, I'm constantly thinking about edging to use and looking for the ideal scenario. This thinking is complicated by the fact that in many areas, the beds tend to expand each year so I'm somewhat reluctant to put in something permanent.
So, what are everyone's thoughts? Inexpensive, durable and easy to install would be nice. Ability to get below ground level to stop the underground running is pretty imperative.
