So your saying rip out the whole plant, cut and replant the tops?
Yes. With stem plants, I mean. Don't try this with an Amazon sword. g
Just cutting the top off a stem plant and discarding it, leaving the bottom, is
called "topping." It's not recommended for many stem plants like Cabomba; it
makes the plant straggly and unattractive.
