Thanks again Stan!
I performed the "surgery" today, but it was more of a butchering rather than a surgery! I ended up breaking off two of the longer sprouts, and was left with just one sprout after I put some fresh nutrient rich (including peat moss) top soil along the one side of the rhizome.
After I got rid of most of the predominantly clay soil along half of the rhizome, I replaced the clay with the fresh top soil, and watered with miracle grow. The leaves of the smaller sprout that was left were already starting to turn green an hour or so after watering them. Hopefully, breaking off the two bigger shoots will help the rhizome focus on root development and growing into that fresh top soil I added along side of it.
Hopefully I didn't kill it either!
Of all the plants for this to happen to, I'm glad it was the Cascade though... from what I've heard they are the most resilient and easiest to grow. Time will tell though...
