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.

I haven't even seen improvement of it with densely planting, but maybe it's just the particular plants I'm growing.

The type of plants definitely plays a role. Like rotala blood red will send out roots a lot more readily compared to rotala wallichii. Trim duration also plays a role as well; the more mature the stems are, the more likely they are to send roots out. I probably see fewer instances of aerial roots showing up because I tend to uproot and replant every 2-3 trim cycles, or about once every 1.5 months for fast growers. like Rotala blood red.
