Sassafras Propagation???

My vacation is winding down. Three weeks on the shores of Lake Michigan. Perfect.

We have been working on erosion control during this vacation. We put down straw blankets over a fairly steep slope that needs stablization. I will throw down some rye seed before we go, and there is already some Sassafras coming in. My goal is to stabilize the soil enough so that the native plants will seed in. I may want to help that along, however.

Does anyone know how to propagate Sassafras? I am from Zone 4 world where we don't have the beautiful Sassafras, but would love to help it along on our sloped area.

Thanks to all (or anyone) who read this blog.
