Problem with my Rhododendron - Knowledgebase Question

My Rhododendron is looking pretty bad lately. Brown spots on leaves, wilted leaves, etc. The flowers bloomed earlier this year but died and turned brown really quickly. Anyone have any suggestions on how I should treat the plant?

I've attached a couple photos. Thanks!

It could be suffering from drought. Has it been through a dry summer? Lack of moisture one year may result in fewer or poor flowers the following year as the plant needs water to help form buds .Rhododendrons can also show the symptoms as you described if they have been exposed to wind too.
Remove any damaged parts of the plant and clear up debris underneath it.
Is your soil acidic? Rhodos need a low PH to survive, and prefer rain water to tap water if possible.
A Spring feed next year with a fertiliser specifically for acid-loving plants should help.

Good luck

Mine looks like that, would it be beneficial to cut it back? Mine doesn't get a lot of sun
