That's good advice DebG - take out a third of the old stems when it's finished flowering. Next year after flowering do the same with another third of the old stems, and the following year do the same with the remaining one third. That way you'll have completely rejuvenated the shrub without losing any flowers.
A sprinkling of Fish, Blood and Bone each spring and it'll be a picture
