Worried about Rhodo getting huge
Please forgive this silly question but I know absolutely nothing about most shrubs and trees. We recently moved into a new home in which we had to plant the lawn as well as the beds. My father, who loves to garden came over with a white Rhododendrom and planted it into the front bed against the house. We have a beautiful window about 2 feet above the shrub. My father tells me this can never be pruned, which concerns me. We moved form a house that had massive overgrown rhodos that I hated. I really don't want a huge shrub in front of my house, much less covering our picture window. Is my Dad mistaken? Can we prune this before it starts to grow out of hand? If so, when is the best time to do it? I'd really appreciate any and all help.
