Absolutely right. We typically uproot all stem plants, trim the best part
off the top and replant the top. We toss the root end and do a little
surface vacumming in that area. This avoids the problem of unsightly "water
roots" and, I conjecture, stirs the top part of the substrate enough to
remove any waste material or alleochemicals generated by the plant,
preventing it from "poisoning" itself. Also, it will get replanted in a
slightly different spot where there has not been a concentrated "nutrient
uptake" by its roots. Sort of like crop rotation <g>.

We typically don't do this in crypt groves or with larger rosette plants.
They only get yanked every year or two. We just moved a large E. horemanii
in the 120g tank from "front and center" where it blocked our view to a
rear corner. Quite a job.
