I do the same with Cabomba. Mine tends to generate an abundance of new
stems out of the substrate and I can then cut out the old stem if it gets
ugly looking.

I do that, too, if I want to propagate it. But I find it tends to make the
Cabomba straggly. If you don't top it, it gets much thicker, with that nice
"bottle-brush" look.
