I try to minimize root disruption. I wash the plant and root ball with water and then plant in the viv. I don't remove all the soil from the roots though I have done that in the past with decent results. I've had good luck so far - most plants in our vivs are doing pretty well. There are a few pics in my gallery of what we have planted. I continue to experiment with plants and setups (working on vivs 7 and 8 now) and seem to be doing better with time.
