Cambomba roots from nodes

[Akshay]

Hi all
My Cambomba sometimes develops these roots from the nodes.
Rotala H'ra does it too, but not as aggressively as the Cambomba.
Any ideas why this happens?

Completely normal and is one of the maintenance requirements if you want to keep it as sexy as @GreggZ does. Some folks say more nutrients at the sub can help, and this may be the case, but haven't noticed it myself.

One of the reasons you'll see it happen is lack of form compaction. If there's too much space around the bush, they send roots more frequently, and the stems tend to lean. Planting density helps a lot. That being said, I don't think there's any real way to prevent this other than trimming and replanting densely.
