You are welcome kloof.
Producing flowers and seeds can really take it out of a plant, especially if it is not very vigorous to start. What I do with my azaleas is wait until the flower either drops off or will come away with the gentlest of pressure.
This leaves a stem, a swelling which is the forming seed and a long thing like an aerial. I then cut through the stem bit, being careful not to cut into the wood as Tambo says unless you want to prune at the same time, with a delicate pair of bonsai scissors. I also sprinkle dried blood and bonemeal on the surface of the soil and water it in with a dilute mix of Miracid and rainwater.
If you do that you should see a healthier plant but it may be a dwarf species and may not grow very large anyway.
