Dividing Ornamental Grasses

As we approach the Second Annual Great Flatbush Plant Swap, I'm hoping to post some tips on how to divide perennials to bring to the event. Now is the time to do it, as foliage has just emerged, plants are actively growing, and most will recover quickly from any perceived insult of being lifted out of the ground and ripped into pieces.

I have to do with this with perennials in my gardens, so I'll use them as examples. Today I divided one of my larger grasses.
