Old, unkempt hibiscus
We recently moved into a house that is surrounded on two sides by hibiscus plants. The house was unoccupied for some time and the hibiscus are fairly ugly and old looking. They really only have new growth on the very ends of branches and the branches are long and spindly. Many of the branches are covered in moss and such.
Is it possible to get these to be beautiful again by pruning? Or should I chop them off and see if they'll regrow? Or perhaps just dig them up and replant with young hibiscus plants?
