How do I divide overcrowded dymondia?

This plant will benefit, substantially, from dividing when it gets over-crowded. What you will want to do is dig up as much as possible, shaking the dirt out. Split them up by pulling them apart from one another. Plant half back in to the original area and the other half wherever else you want them. Make sure to water-in everywhere you plant to set the roots back in the soil properly.
