Rhododendron - help

[RobC]

I have a rhododenron that is desperately in need to some tlc (and pruning I think).  We moved in to our current house a couple of years ago and soon had  6 leylandii taken down as they were casuing alot of shade.  This has re-invigorated one of the rhododenrons but not the other.  The one that is still struggling is approx 2 metres tall and at least 2 metres in diameter.  It has produced one or two flowers this year.  It has grown mainly in one direction, and is very woody.  There branches are a tangled woody mess.  In its current state it is an eyesore.   What should I do?

Bit late now, but you can prune them down as low as a foot above the ground in spring. Try feeding with Miracleacid or some such ericaceous food.
