We have talked about turfgrasses and erosion before, but two weekends ago I was on the Gulf Coast and was able to witness this in practice one again.
Along the Gulf Coast a simple but important grass grows - Sea Oats. Sea Oats can tolerate the salty spray from the ocean and they have dense root systems. This makes them perfect for preventing erosion on beaches. The grass grows mostly on sand dunes and is a protected species in some areas. In fact, the sea oats we saw were completely fenced off and there were warning signs cautioning visitors against disturbing the plants.
All of that, for a Monocot.

Then I used my Felco hand pruner to cut off last years growth about 6-8" high.
Since, I only have three, this was not a problem. If I had a lot of grasses, I would use a hedge trimmer. A hedge trimmer makes the job go really fast!
