We inherited a very old scraggly large rhododendron. It was never in
very good shape and we have done a lot to try to improve its health:
extra water during dry summers, added iron and added epsom salts,
special rhodo fertilizer. All to little avail.

Some photos of the poor quality lime green leafs and spotting can be
found he

Any assistance on whether we can do anything further to help this
plant would be appreciated.

You don't say where you are or what sort of soil you have? if you are in a
drier part of the country or your soil is unsuitable naturally then you will
never win. If you are in a good place for them then heavy watering (hose on
all day) and organic mulching may help as may hard pruning to encourage new
growth from the base, takes a few years for the plants to resume flowering
but does re energize them
