Do you guys have any advice on trimming plants? What different methods do you use? How important do you think trimming and thinning is?
I'm thinking of primarily long leaved plants such as hair grass or vallis, the type of aquascape I'm going for needs the background plants to be trimmed in a kind of v shape. Can you just cut vallis off at the desired height? Where does the leaf regenerate from. When I've grown vallis in the past it has grown up and over, sometimes round and round the tank itself, i.e very long if you held it upright.
What about other plants such as amazon swords, do you just cut them off at the base of the plant because once planted the leaves are hard to strip off.
