Why are you wanting to prune? Not usual to seriously prune the genus.

Previous question
If you mean a hard prune back into heavy wood, this really only works with deciduous Azalea's and the larger leaved Rhododendrons (all technically in the genus Rhododendron).
Do you know which type, variety names?
