I am happy to report that I have some new root growth. One of the existing roots has "branched off" part way down its length and I now have about an inch of new growth. I was hoping some new roots would grow from the plant itself, as all the few remaining roots are attached on one side making the plant very unsteady... but at least it's something. No new leaves, but I expected the roots to come first anyways. Hope this is a good sign!
