I had the same experience as you the first time around and rotted a few bulbs. I believe you are better just cutting off any roots that come on a dormant bulb because all of the white new growth I have witnessed on my S.A. Amaryllids has been a new shoot from the plate, while all of the root remains that came on the bulbs either rotted off with moisture, or dessicated. If the bulbs are showing any rot, I would clean them up and let them air out in the driest place you can put them for a few days, or until it dries over. If your Boophane is showing fresh white root growth that you pulled out, just gently dig a long hole and do your best to drop the root in without breaking it. It should be fine, and now you know your bulb is in cycle!
Goodl luck.
The H. albiflos I have are seedlings and don't seem to mind being watered all the time, but I haven't tried acclimating a dug bulb. They seem to be pretty bullet proof compared to many others.
