As we know virtually all the aquarium plants we buy are grown emersed so when we place them underwater the leaves die back to be replaced by new growth more suited to growing underwater underwater, hence the benefit of trimming or removing the leaves...
I was questioning the logic in trimming back a hardy established plant while in its emersed state?
I honestly don't know the answer but, I dont normally cut back my pot plant & stick them on the window sill, at least not until they have adjusted & grown.
