Pruning
Opinions differ concerning how much pruning the shrub needs. The University of Missouri Horticulture Department suggests minimal intervention, so long as the plant has enough room to develop, up to a maximum height of and a potential "spread" of . Others suggest more active intervention to encourage development of new flowering branches and buds, with decisive pruning immediately after flowering.
