You cut off the top portion which is the growing tip end, and plant the top portion as a new plant; the length depends upon what you want, but most people cut it down at the point where it begins to look scraggly. The lower portions of stem plants tend to look this way, even losing leaves completely, due to less light reaching them and the tops are closer to the light, growing toward light. The bottom portion you pull out and discard. This is done regularly to keep the stem plant at a specific general height.
On the Anarcharis, as I mentioned previously it prefers cooler water, room temp or lower even, so it will not be as fast growing as some other stem and floating plants.
